4. 4 LANDSCAPE HAWAII JANUARY | FEBRUARY 2015 Hawaiiscape.com 5THE VOICE OF HAWAII’S GREEN INDUSTRY PRESIDENT’S COLUMN Take a stand. The legislative season has begun and if this year is like past years, you can expect legislative bills on native species, invasive species, herbicides, and a surprise or two. These three areas are areas of change in our state and our industry. Taking a stand is as easy as visiting the state legislative website and completing a simple form. Make it a goal to spend 10 minutesto testify on at least one legislative bill that will affects you. Where do we stand as the landscape industry on these issues? Native species. We encourage the use of native species. We support native plant horticultural research and funding to increase the number of native species that will thrive in the urban environment. It is difficult to support bills requiring the mandatory use of native species until more native species are available. Invasivespecies. We support the prohibition of the use of invasive plants that have more risk then benefits as determined jointly by conservationists and industry professionals. We encourage the use of the weed risk assessment to assist in making informed plant decisions for the greatest environmental benefit. We support better bio security to prevent invasive pests from entering the state of Hawaii. Insecticides and herbicides. We support the use of chemicals as part of an integrated pest management approach to manage landscapes & pests that would otherwise be unmanageable.

6. 6 LANDSCAPE HAWAII JANUARY | FEBRUARY 2015 By Matt Lyum and Janine Mori LICH Field Trip Installation What’sNewfor2015? THE VOICE OF HAWAII’S GREEN INDUSTRY Hawaiiscape.com 7 A t the LICH post-conference field trip on Octo- ber 10, 2014, a group of industry professionals visited a unique, “behind the scenes” tour of 5 great properties within the “resort” theme of the conference. Matt Schirman of Hui Ku Maoli Ola started us off at Turtle Bay. He described the challenges of installing 565 tons of river rock and equal amounts of soil and plants on a living roof. The Turtle Bay Resort “green roof” project includes three roofs totaling approximately 50,000 square feet. A combination of native groundcovers - mau‘u ‘aki‘aki, Carex (carex wahuensis), and nehe (melanthera integrifolia) — and three colors of river rock were used to create a “living” work of art that is visible from the guest rooms and elevator core above. Janine Mori, of Walters Kimura Motoda was the landscape architect. She describes her project. “The natural beauty of the North Shore, especially the ocean, served as the inspiration for the design. At the east roof which consists entirely of river rock, the mauka portion represents clouds and waterfalls, which then transitions to intertwined curvilinear bands representing a stream. The 18,000 square foot north roof, which includes 4,400 square feet of planting along the building, and river rock closer to the ocean, is meant to resemble the water lapping along the shoreline. The12,360 square foot west roof is entirely planted, and incorporates the same style of curvilinear layout as the other roofs, representing a wave motif. Plant selection was based on Hui Ku Maoli Ola’s experience with native plants, and trial plantings that were done on-site. While the plants are predominantly green in color, the different shades, textures and growth habit provides subtle contrast in keeping with the Resort’s concept of balancing nature, Hawaiian culture and contemporary style. Two areas for herbs and vegetables are also provided as part of the Resort’s farm-to-table initiatives.” After a scenic drive overlooking 10’+ surf, we left the tranquility of nature into the hustle and bustle of Waikiki. Passing by throngs of tourists (and a few rum- maging homeless), the Starwood Resorts’ beautiful landscaping was like an oasis in the urban jungle. Randy Liu gave a walking tour or the Sheraton Waikiki, the Moana, The Prin- cess Kaiulani and the iconic Royal Hawai- ian Hotel. A true, behind the scenes tour, we visited the basement office, traveled in the tunneled corridors of the hotel, and even got to eat a Hawaiian Buffet in the employee cafeteria! Randy described the Starwood branding and how the landscape design played into each experience. The tour got up close and personal to the Moana’s historic Indian Banyan (ficus ben- ghalensis) that has struggled through several damaging renovation projects since it was first planted in 1904. Maintaining lush tropical plants in the coastal environment, Randy’s staff has to also overcome heavy foot traffic and other problematic logistical challenges as well. We could not even access the entire landscape (or take a private group photo) due to the numerous weddings competing for lawn space! Matt Lyum is Owner of Performance Landscapes and Director of LICH.

This year marks the 15th season of certification testing in Hawaii. Three hundred fifty-two landscapers have been certified during that time. Most certi- fications have been awarded for either Turf or Ornamental Maintenance, and many hold certification in more than one module. There are seventy-four LICTs in Irrigation and twenty-eight LICTs in Softscape Installation. Twelve landscapers in Hawaii hold certification in all four modules! PLANET certification raises the stan- dards of our profession by recognizing proficiency in the landscape workforce and upgrading the status of individual landscape professionals. Certification provides employers and the public with a means of identifying qualified landscape professionals. Many landscapers have pur- sued certification for these reasons alone, but some individuals and companies were further motivated to seek certification when the Department of Transportation required the presence of LICTs on the job when submitting bids on highway maintenance in Honolulu County. I think it would be a boon to our industry if Landscape Architects were to suggest LICTs on the job for companies doing installation work throughout the state. But, to see that idea become a reality, we need to have more landscapers certified in Softscape Installation. To that end, LICH will be offering the Softscape Installation test this year in Kona for current LICTs. If you are currently certified in Orna- mental Maintenance, the Softscape Instal- lation test is relatively short. You would need to take two written tests: Softscape Plan Reading and Softscape Horticultural Principles. The field test would consist of only three problems: Sod Installation, Plant Layout and Rototiller. For those certified in (only) Turf Maintenance, you would take the same written tests, the same three field tests with the addition of Plant ID and Tree Planting and Staking. Keep watching the LICH web site www.hawaiiscape.com and this magazine for more information and discussion. I encourage you to give strong consider- ation to add Softscape Installation to your certification qualifications. Get Certified; Be Outstanding in Your Field!

According to Dan Jaeger, Vice President of HRC the green roofing project covered approximately 60,000 sf of the hotel’s lower flat roof areas and included a landscape mix of river rock and gardens consisting of mostly native Hawaiian seashore plants. “The combination of the project size, its intricate design, sustainable elements, and the sensitivity to provide a serene and inspiring view for the resort’s hotel guests make this project unique in comparison to other resorts in Hawaii and around the world.” Segments of the project installation included Single-ply installation, design work and installation of green roofs and rocks, along with skylight removal and replacement According to Scott McCormack, Vice President of Real Estate for Replay Resorts and Turtle Bay Resort said, “With the recent installation of the solar PV system atop the 450-room Turtle Bay Hotel, these conservation projects complement our efforts to be more ‘green’ with our operations, as we fulfill our vision for a more sustainable future of Turtle Bay Resort while contributing to the State’s goal of reaching 70% energy independence by 2030.” Turtle Bay Resort initiated the green roof project to replace outdated roof system, improve its energy efficiency, reduce green- house gas emissions, while also enhancing guest room views. The green roof materials included a layout design of river rocks in various colors and shapes. Native Hawaiian species planted include Mau’u’aki’aki (sedge), Nehe (vine) and ‘Akulikuli (short succulent grass). Other low maintenance plants used are Carex (longer, bright green grass) and Sedum (a hardy flowering plant). Two herb gardens, 6 ft x 18 ft were also planted near the roof elevator areas for easy access provide fresh local herbs and produce used by the hotel’s restaurants as part of the resort’s farm-to-table emphasis. An irrigation system tied to moisture meters was also installed to conserve water. The new low roof design is a col- laboration of Division Seven Consulting of Hawaii, Inc. (Consul- tant overall), Walters Kimura Motoda, landscape architect and architect Robert Alexander Lazo. Hui Ku Maoli Ola contributed to some of the vegetative and rock garden design. Commercial Roofing & Waterproofing Hawaii, Inc. (CRW) was named the general contractor and its Vice President, Larry Young, oversaw the project since work began in August 2013. The project’s first task was to remove three layers of roofs that were installed one on top of the other (red cinder rock over two layers of BUR over eight inches of spray foam roofing). The existing red cinder rock roofing was salvaged for reuse in other areas of the resort. In addition, there was approximately 50 sq yds of dirt, 3 ft deep that was removed discretely in 5 gallon buckets with no disruption to hotel operations or trace on the premises. HRC discovered struc- tural corrosion and the metal deck substrate was replaced. Accord- ing to Jaeger, the entire removal process spanned over 6 months. A goal of this lower roof project was to provide an aestheti- cally pleasing view to enhance the hotel guest experience while maintaining a natural ambience that blends with the surround area. This project was a 100% Firestone Roofing product project for Turtle Bay Resort, including a Multi-Layered Green Roof over Single-ply Thermoplastic Polyolefin membrane, water-based bonding adhesive, 5/8” DensDeck, IsoStick Adhesive,Tapered Insulation and V-Force Vapor Barrier with water-based primer applied to the existing lightweight concrete. Standing Seam Metal Roofs were also installed. Approximately 500 tons of stones were used to fill the design of the green roof. The stone were specified to meet rooftop wind ratings. The loading process took approximately 90 days to complete using a HRC 10-man crew. One pallet at a time was de- livered to the loading site and then hand carried up to the roofs. Four hundred (400) Standing Seam Roof panels were care- fully installed using HRC’s 3-man crew per panel. The Standing Seam Roofs can now be found covering both the Resort’s Spa and Pa‘akai Restaurant.

According to Dan Jaeger, Vice President of HRC the green roofing project covered approximately 60,000 sf of the hotel’s lower flat roof areas and included a landscape mix of river rock and gardens consisting of mostly native Hawaiian seashore plants. “The combination of the project size, its intricate design, sustainable elements, and the sensitivity to provide a serene and inspiring view for the resort’s hotel guests make this project unique in comparison to other resorts in Hawaii and around the world.” Segments of the project installation included Single-ply installation, design work and installation of green roofs and rocks, along with skylight removal and replacement According to Scott McCormack, Vice President of Real Estate for Replay Resorts and Turtle Bay Resort said, “With the recent installation of the solar PV system atop the 450-room Turtle Bay Hotel, these conservation projects complement our efforts to be more ‘green’ with our operations, as we fulfill our vision for a more sustainable future of Turtle Bay Resort while contributing to the State’s goal of reaching 70% energy independence by 2030.” Turtle Bay Resort initiated the green roof project to replace outdated roof system, improve its energy efficiency, reduce green- house gas emissions, while also enhancing guest room views. The green roof materials included a layout design of river rocks in various colors and shapes. Native Hawaiian species planted include Mau’u’aki’aki (sedge), Nehe (vine) and ‘Akulikuli (short succulent grass). Other low maintenance plants used are Carex (longer, bright green grass) and Sedum (a hardy flowering plant). Two herb gardens, 6 ft x 18 ft were also planted near the roof elevator areas for easy access provide fresh local herbs and produce used by the hotel’s restaurants as part of the resort’s farm-to-table emphasis. An irrigation system tied to moisture meters was also installed to conserve water. The new low roof design is a col- laboration of Division Seven Consulting of Hawaii, Inc. (Consul- tant overall), Walters Kimura Motoda, landscape architect and architect Robert Alexander Lazo. Hui Ku Maoli Ola contributed to some of the vegetative and rock garden design. Commercial Roofing & Waterproofing Hawaii, Inc. (CRW) was named the general contractor and its Vice President, Larry Young, oversaw the project since work began in August 2013. The project’s first task was to remove three layers of roofs that were installed one on top of the other (red cinder rock over two layers of BUR over eight inches of spray foam roofing). The existing red cinder rock roofing was salvaged for reuse in other areas of the resort. In addition, there was approximately 50 sq yds of dirt, 3 ft deep that was removed discretely in 5 gallon buckets with no disruption to hotel operations or trace on the premises. HRC discovered struc- tural corrosion and the metal deck substrate was replaced. Accord- ing to Jaeger, the entire removal process spanned over 6 months.

A native of Reading, Pennsylvania, Da- vid Lingenfelser started as a meteorology undergraduate student at Penn State, but soon found that he was more interested in studying his high school hobby of rais- ing rare tropical plants. After transferring to the College of Tropical Agriculture and Human Resources at the University of Hawai‘i, Lingenfelser received his undergraduate degree and began his graduate work in 2012 in Dr. Leonhardt’s lab. Lingenfelser’s poster, “Polyploid initia- tion in Hawaiian tree species,” explained his research on developing improved ornamental trees and plants using various concentrations of oryzalin, a dinitroani- line herbicide which temporarily halts cell division. Applications of oryzalin can result in an extra set of chromosomes, which can in turn, change plant charac- teristics (i.e. thicker leaves, larger flowers, higher levels of chemical compounds, and sterility). The seven plants he used for his study were Schefflera actinophylla (octopus tree), Clusia major (autograph tree), Heritiera littoralis (looking glass tree), Thespesia populnea (milo), Calophyllum inophyllum (kamani), Jatropha curcas (jatropha), and Plumeria stenopetala. Varying amounts of oryzalin were applied to seedling meristems in the lab, and four of the seven species resulted in polyploid plants. The treatments did not work for autograph tree or kamani, as there were no changes in the number of chromo- some sets. For the four species in which the treatment succeeded, the resulting plants were awaiting outplanting to the field when Lingenfelser graduated. “I haven’t checked back to see if they have been outplanted,” said Lingenfelser. “This is a really long-term project, with the in-lab work and field work on trees that may take four or more years before we can see if they produce viable seeds, or if they need to be crossbred with other diploids so that offspring are also sterile.” That’s for the next graduate student. For now, Lingenfelser is concentrat- ing on his next project, a new job with the Hawai‘i Department of Agriculture, protecting Hawai‘i from invasive species. When asked if he was planning to return to Pennsylvania, he laughed. “No, I don’t like cold weather.” Student: Bishnu Bhandari, University of Hawai‘i at Mānoa College of Tropi- cal Agriculture and Human Resources Department of Plant and Environmental Protection Sciences (Dr. Zhiqiang Cheng, advisor). Masters student Bishnu Bhandari’s poster, “Trunk injection of systemic insecticides to control stem and leaf gall wasps, Josephiella spp., on Ficus microcarpa in Hawai‘i,” reported on prelimi- nary results observed during the first 14 months of this two-year research project. Ficus microcarpa, commonly known as Chinese banyans, are widely planted in Hawai‘i. In recent years, these important trees have been sickened by what arbor- ists and landscape industry personnel observed as an overabundance of pests that quickly attacked new leaves and stems of the trees. Although the leaf gall wasp (Josephiella microcarpae) that are attacking Chinese banyans have been present in Hawai‘i since 1989, a new stem gall wasp (Josephiella spp.) arrived and was found in 2012 attacking the already weakened trees. Earlier work by UH’s Dr. Zhiqiang Cheng found that soil drenches of insecticides were ineffective for controlling these stem and leaf gall wasps. In Sep- tember 2013, Bhandari joined Dr. Cheng’s lab and started work on trials to inject insecticides directly into the trunk of Chi- nese banyans on the UH Mānoa campus. With assistance from UH Landscaping and Arbor Jet, 45 trees were selected for the study - some used as controls (no insecticide treatment) and others injected with imidacloprid, emamectin benzoate, imidacloprid + phosphorus acid, or emamectin benzoate + phosphorus acid. The injections were made just once, with Bhandari conducting stem and leaf gall counts on new branches each month. Although the study is still ongoing, results after four months showed that all treated trees showed significantly less galls than the control. It appears that emamectin benzoate was more effective than the other treatments. In addition to ongoing monitoring, Bhandari will also conduct pesticide residue analyses for each of the treatments, which should help identify appropriate reapplication intervals. A graduate of Tribhuvan University in Nepal, Bhandari sees this as the perfect project. “Where I come from, banyans have cultural and religious importance,” said Bhandari. “I come from a farming family and I hope to someday earn my PhD and return home to Nepal. The opportunity to come to Hawai‘i, to be supported in my studies, and to do some important research is amazing.” Congratulations to our students and mahalo once again for a successful conference. The LICH poster committee looks forward to reviewing abstracts for the 2015 session.

Mulkern Photos: BY Brandon Au (Above) Scoops of soil for planting the coconut; (Right) Ceremonial coconut with honorary gold shovels Photo courtesy: Scott Kubo The uplit Keawe tree A rbor Day, founded by J. Sterling Morton, was first observed on April 10, 1872 in Nebraska. National Arbor Day is the last Fri- day in April, but Hawai‘i commemorates Arbor Day on the first Friday in November. To date, Hawai‘i has celebrated Arbor Day for 109 years and the Arbor Day Foundation has recognized Honolulu as a Tree City USA for 33 years. You can find out more information on the Arbor Day Foundation’s website at www.arborday.org. This year, The Mayor’s Arbor Day ceremony was held on Friday, Novem- ber 14, 2014, at Kawaikui Beach Park in East Honolulu. The Division of Urban Forestry (DUF), Department of Parks and Recreation, planted two Singapore plumeria trees and six coconut palms for this celebration. The design allows a clear view to the scenic beauty of the ocean from Kalaniana‘ole Highway and matches Hawaii Loa Ridge’s plumeria trees at the turnaround. Dignitaries and participants were de- lighted with a poetry reading and hula per- formances by students from Holy Nativity School. During their reading, the second graders stated that it takes 5 trees per person in order to provide enough oxygen. We definitely need to plant more trees! Two coconut palms were selected to be “planted” in honor of this Arbor Day. Traditionally, mulch would be shoveled as the final step in tree planting, but due to the risk of coconut rhinoceros beetle infestation, soil was used to complete the planting. Everyone, including the students, participated in shoveling a scoop of soil using ceremonial gold shovels. We thank the Deputy Managing Direc- tor, Georgette Deemer, who presented the Mayor’s proclamation designating November 14, 2014, as Holy Nativity School Arbor Day. These students will be the stewards of these trees as they grow. Also thank you to Michele Nekota, Parks Director; Jeannie Ishikawa, Parks Deputy Director; Jon Henington, Parks Public Information Officer; Tara Hamano- Hirohata, Regional Park Manager, Park Maintenance and Recreation Services; Cisco Martin del Campo, Honolulu Bo- tanical Gardens Recreation Specialist, and the staff of DUF. In the spirit of Arbor Day and with the necessity of growing our urban forest, more trees need to be planted for our health and well-being. Trees are coming soon to your neighborhood!

W hen we started in business in 1975 we wwere fortunate to develop a relation- ship with the Kuni- yukis who owned and operated Veteran’s Electric, distribu- tors for Nightscaping. The family was a fantastic resource and became personal friends. They also had strong ties to Bill Locklin, owner and lighting innovator for Nightscaping, who provided support for the Kuniyuki’s family business. With his manufacturing plant in Redlands, CA, Bill helped with the night lighting at Disney- land. When Veteran’s Electric closed, the Kuniyukis opened Dramatic Garden Lighting. As they had been so support- ive of us, we thanked them by providing them a landscape master plan for their new shop; unfortunately, the photo of our rendering doesn’t show the Nightscaping well lights we used to up light the trees. When talking about “the old days”, we would be remiss if we did not mention Sholem Klopfenstein. Although he’s no longer involved with Klopfenstein’s Light- ing Inc., the staff is very knowledgeable, and the company represents over 100 lines of fixtures and control systems. The company has grown since Sholem started in the garage of his Kalama Valley home that we landscaped. Today’s contractors have numerous sources, and it’s coincidental that most of them are located in the same area, Kalihi, such as Diamond Head Sprinkler and Kona Irrigation, and Hisco and Pacific Pipe are just down the road. These companies also offer many outdoor lighting products now. The greatest benefit is, along with irrigation seminars, they also give night lighting classes. You want to get on their email lists and look at their showrooms for specific information on products and classes. For consumers, City Mill, Home Depot and Lowe’s offer a variety of homeowner products. It is hard to choose from the selection available today. Hawaii is fortunate. We have a local manufacturer who distributes worldwide and is internationally acclaimed, Beach- side Lighting. I had the good fortune to meet Rick Benedict when he first opened in his 10’ x 10’ “world headquarters” in Ka- lihi, a couple blocks away from Dramatic Garden Lighting. I’m sure droves of contractors have helped him develop his line, but I like to take credit for the suggestions I made about corrosion and small parts that often got lost when changing light bulbs up in trees. He’s addressed every flaw I’ve found in competitor’s products. A lot changed with the advent of LEDs. Early light fixtures took advantage of incandescent bulbs used in the automotive industry. Then, there were the MR 16 lamps that I still refer to as the slide pro- jector light bulbs. They lasted forever and came in a variety of wattages and beam spreads, making them ideal for lighting a low spreading plumeria or a 50 foot coconut canopy and trunk. Wire sizing was critical, as voltage drop can be significant in longer wire runs. Today, we’re adjust- ing to using 3, 5 and 9 watt LED fixtures that may last longer than we live. Some things remain the same. Nothing beats a great design, good weatherproof wire connections and proper wire sizing. Warranties are always important when selecting a product line, since everything will need maintenance in the end. Kevin J.

Wire sizing was critical, as voltage drop can be significant in longer wire runs. Today, we’re adjust- ing to using 3, 5 and 9 watt LED fixtures that may last longer than we live. Some things remain the same. Nothing beats a great design, good weatherproof wire connections and proper wire sizing. Warranties are always important when selecting a product line, since everything will need maintenance in the end. Kevin J.

For Information call: 808-677-1580 or visit tensarcorp.com/EC_LandHI W ith the introduction of LED technology in the past 5 years, the installation side of landscape lighting has changed dramatically and for the better. Traditional landscape lighting at 12 volts was limited to load (wattage) and distance. Basic rule of thumb was 100 watts for 100 feet using 12/2 gauge direct burial cable. To extend cable runs, you would have to increase cable size as well as increase voltage from 12-13-14 or even 15 volts. This now requires using a volt meter to determine what the voltage would be at the 1st fixture knowing the voltage would be lower at the 2nd, 3rd, and remaining fixtures. This was called voltage drop, meaning lights closest to the transformer would be brighter due to receiving higher voltage then the fixtures farther away. Traditional incandescent and popular Halogen light sources operate off a filament wire coil. The higher voltage, the hotter the filament would burn, creating a brighter light. The opposite was true if you supplied lower voltage to the filament, lower temperature, lower light output and a warmer color would be produced. What does this all mean? The landscape lighting installers of the past were very challenged to deliver as close to 12 volts to each fixture or have varying colors and light outputs throughout their projects. Not to mention short life to the light bulbs creating maintenance issues and frequent call backs. Today, LED’s have made the installation process simpler, with virtually no voltage drop. Why ? LED’s operates through a driver that can receive a voltage range (9-18volts) and then supply the LED the correct current in a constant, stable man- ner. So no matter where on the Cable you place your landscape lighting fixtures, each LED has its own regulating (driver) device to operate the LED correctly and efficiently. No more need for voltage meters, especially for residential jobs when cable runs are typically under 250 ft. from the transformer. Using LED’s allows for 1000 ft. cable runs with a 12/2 cable. Using a 14/2 cable, 250-500ft are standard which were impossible with traditional light sources. The other key when using LED’s is wattage. LED’s operate at 1/4 to 1/5 the wattage of the traditional light sources. Meaning a 4 watt LED is equivalent to a 20 watt halogen, that’s 75-80% savings in wattage. This holds true for most LED light sources compared to traditional light sources. The lower wattage drastically reduces the resistance in the cable allowing for more fixtures and longer cable runs coupled with a driver controlling each LED fixture. This makes for a highly regulated system of great integrity. Long life LED’s have an average life rat- ing of 50,000hrs. This means at 6 hours per night, the LED lighting system can provide over 22 years of operation vs. the average life of 2,000-5,000 hrs from an incandescent/halogen light source. 10 times the life equates to 10 times or more not having to buy or replace the old light sources which could be in difficult places to get to such as water features, high ceil- ings, architecture, or specimen trees. The long life of LED’s has made life much better for everyone except lamp maintenance contractors. Replacing light bulbs is no longer an annual event like before. Transformers for LED landscape lighting: With 75-80% less wattage or load, large transformers are no longer needed. 60- 100 watt transformers are replacing 300 and 600 watt transformers of the past. There are definite savings recognized with smaller transformers. We still have all the great control options with timers & photocells. On the control side technology is advancing here as well.

16. 16 LANDSCAPE HAWAII JANUARY | FEBRUARY 2015 Hawaiiscape.com 17THE VOICE OF HAWAII’S GREEN INDUSTRY Cable for LED landscape lighting: As mentioned earlier, there is no need for thicker, heavier gauge, expensive cable anymore. 12/2 and 14/2 direct burial multi strand copper cable can support 95% of the projects of today. This is a great feature and again saves money in the LED system costs. Remember, cable can be as high as 25% of the job cost. LED Fixtures for landscape lighting: Retro fit or Integrated LED’s Both use the same housings that the traditional landscape lighting fixture uses. The only difference is the plug and play LED’s can retro fit into existing landscape lighting fixtures. However, it is highly recommended if retrofitting new LED’s into an existing fixture you replace the old socket with a new one to ensure solid contact and avoid arching. Both have their features and benefits. Retrofit LEDs are less expensive and very easy to replace or install in the fixture. Integrated or module LED fixtures are engineered for better performance and design to dissipate heat as well as keep water out of the fixture. The more light needed, the greater the chance you will need an integrated LED fixture. Applications for LED fixtures in landscape lighting: The LED fixtures today are very similar to the ones of past. Some can be smaller due to the physical size of the LEDs compared to traditional light Sources. LED fixtures can be used in all 4 types of applications for landscape lighting: Area, Path, Directional, and Specialty. Areas lights are used for larger perim- eters, they have greater light outputs (up to 30 ft. diameter coverage). They are great for driveways, highlighting groundcovers, pool decks, putting greens, and even stairways. Recommended spacing is usually personal preference; however most people prefer pools of light with a separation of darkness in-between to guide you out of the area or space safely. Over lapping lighting is used more for commercial applications to insure clear transition through the space. Spot lights use projection type LED’s like MR16, MR11, MR8 that produce a specific beam angle based on the LED reflector or lens to create narrower beam angles to spot or accent key objects in the landscape or hardscape. Spacing is determined by viewing angles and coverage of the object. For example, lighting a large canopy tree in the center of the yard will typically need 3 fixtures triangularly spaced from the base to provide equal coverage from all angles, that way the viewer can see the tree from any position. If the tree is linear (palm tree), 2 fixtures can provide full coverage. All LED Projec- tions light sources come in various beam spreads and wattages. For residential applications, 15-20 degrees are used for palm trees, 25-50 degrees for medium width specimen trees, and 60 degrees for wide, low level plant material such a Sago palms and Pigmy Date palms. Flood lights use Omni directional LEDs or LED strips & panels to provide wide angle output or flood lighting. Because the light outputs are wide angles, these types of fixtures are rectangular in shape allowing large amounts of light to exit the fixture. Washing walls, signs, hedges or even wide plant material is where these fixtures perform the best. Positioning Flood lights is a function of coverage of the object to be lit and mounting space. Never place fixtures into turf because of the required maintenance of watering, mowing equipment, and foot traffic. This can create high probability of damage or alignment issues to the fixture. It is best to mount within the planter space for better protection. Spacing is based on desired effects. Signs are normally washed evenly and framed with little spill light. Hedges can be done in a similar technique or again spaced with intermittent darkness between light. Flood lights are often mounted right at the base of the object to provide complete coverage without being in harm’s way. Specialty LED lights are usually for special installations or applications such as underwater, hanging, step light, brick , paver, BBQ, basket , putting green, bocce courts or decorative wall , ceiling or hardscape pedestals. Mounting these fixture types can be more challenging but still are a mainly a function of personal choice. The absolute beauty of LED landscape & hardscape lighting is the flexibility of the wiring system. Since the cable is not required to be buried, you can easily move fixtures into any desired location, creating the effect you want, and hiding the cable once complete. The above simple guidelines, added to the wonderful new technology of LED lighting, will provide stunning effects to all your projects. Safety, security, and most important, beautification are the great bi products of this lighting system. Once installed, you can relax and enjoy the system for years … but remember, things grow so maintenance is required to keep the system intact.

18. Hawaiiscape.com 19THE VOICE OF HAWAII’S GREEN INDUSTRY Technological Advances in Low Voltage Landscape Lighting The Low Voltage Landscape Lighting Industry has changed a lot since I started in 1985. It was thought that “Low Voltage” had a distinct advantage in landscapes. In theory, a 12-volt system was much safer in a landscape environment than a 120-volt system and their energy consumption was a lot less. The job of a fixture was to hold the bulb, and, it had to do it well. This meant that a fixture had to be moisture resistant and tough enough to last in an outdoor environment. Often, fixtures in the Hawaiian Landscapes simply did not last. The interaction of soils and salt air took its toll on many fixture manufacturers in this state. In fairly recent years, major manufacturers have incorporated the use of Brass and Copper to solve this problem. In addition some of those manufacturers have begun using high quality aero space zinc and aluminum materials along with advanced powder coating techniques. It is no longer hard to find manufacturers that offer the type of quality fixtures that we require at varying price points. In the past, many of the bulbs used in this industry came from the automotive industry. If you think about it, automobiles put out a lot of light as they made their way down dark streets at night. In addition we became very dependent on the taillights of the driver in front of us to tell us what they were doing or where they were going. So, why couldn’t we utilize this proven and dependable technology in landscape lighting? Imagine the low impact to our electric bill. Those bulbs put out a lot of light and only used a 12-volt source from a battery! One of the challenges was the fact that those light bulbs didn’t last long. They would burn out quickly. I remember after finishing a lighting job I would furnish my customers with a box of bulbs anticipat- ing burn outs in a relatively short period of time. I think at one point in time, a lot of the industry moved away from low voltage lighting for this very reason. Enter the era of the Halogen Bulb (lamp)! This was an era that in my opinion made tremendous changes to the Landscape Industry. Halogen offered us fantastic color control and long lamp life. Some Halo- gen lamps offered as much as 10,000 hours of life. Suddenly the industry comes alive again. Manufacturers also incorporated a number of reflective options that provided us with various beam spreads. This coupled with a choice of wattages provided the lighting designers with a lot of tools to create beautiful effects. I loved this part of my trade because it awakened a creative part of me that continues to evolve to this day! In Hawaii we have the perfect environment, plant pallet and now lighting equipment to create stunning nighttime themes within our own back yards! More of this to come in future articles. Back to the Halogen lamp. In its con- struction a halogen lamp is technically an incandescent light bulb. The biggest difference was the introduction of Halogen gas into the bulb. During the life of an incandescent bulb a filament burns and glows (this is what produces light). As it burns, black carbon is depos- ited on the inside of the bulb. After a certain time the filament gets thinner and thinner as more and more carbon leaves and eventu- ally the filament is too thin and breaks. The bulb no longer glows. At high heat (5000 degrees Fahrenheit) halogen lamps go through what is called the halogen cycle. The halogen gases in this phenom- enon of science re –deposits the carbon back on to the filament. This is how longer lamp life was achieved. Halogen lamps changed the industry so much that lighting geeks like myself no longer refer to them as bulbs. We now call them Lamps! Tech tip: Many people have asked me how to dim Halogen lamps. In a future article we will discuss the engineering of systems. But in an effort to address this particular question, It is important to note that Halogen Lamps need to run at a voltage of between 10.5 – 12volts. The act of dimming required the back- ing off of power below that 10.5 mark. When this occurs the lamp will begin to dim. However a few things occur. Firstly the color changes, often times turning yellowish. Secondly when a lamp is run below the rated voltage they do not burn hot enough to complete the Halogen cycle, therefore the lamp life is compro- mised. One thing that you can do to help with this is to occasionally run the lights at full power 10.5 – 12 volts, which will redeposit some of the carbon back onto the filament. The technological advances did not stop here. In recent years the use of LED’s (Light Emitting Diodes) have become very popular in our industry. Remember the halogen cycle? LED’s did not have this issue. They don’t have to run hot; in fact they are sensitive to heat. Soon a whole industry of lamp and fixture manufacturers started designing them into homes, offices, and hotels… One of the advan- tages was its ability to illuminate without generating a whole bunch of heat. In addition LED’s are very efficient. It is common for a 50-watt equivalent LED to utilize only 13.5 watts verses 50 watts and get the same light output. Today better energy efficiency can be realized through the use of LED technology. However as with every new advance- ment, there comes a whole new set of challenges. The light output from LED’s sometimes came out as a light blue and often times a very bright white. It didn’t look good on the plants, sometimes harsh and unnatural. So manufacturers incorporated different colored lenses to get color temperatures where they needed to be. Competition for business has also driv- en LED prices down. Unfortunately often, the way that this was accomplished was by importing LED’s from overseas and or from seconds from major manufacturers. This in some cases had put a bad taste in the mouths of the end users who often suffered with inconsistent light output and short life span. Remember: not every LED is a good LED. Don’t sacrifice price for quality. Today, the things that we regularly have in our hands and at the control of our fingertips is what is driving innovation in manufacturing. I am speaking of our smart phones and pads. In addition Smart Home technologies are beginning to become an asked for feature in many homes. While at the moment they are pricey, there will come a time when most home- owners will be able to enjoy the benefits of these types of systems. So hold on to your hats as this technology is already in the Landscape Industry and partner- ships with the smart home companies are being formed today. It’s the next level of control! Imagine for a moment, having the tools that will enable you to control the mood and effects of your or your clients very own back yard resort. Imagine having individual control of every single light on that property. Imagine being able to do this with an IPhone, Android or Pad. This is the kind of technologies that our Low Voltage Landscape Lighting Industry is headed for. In addition we have a myriad of options in lamps, fixtures and controls all enabling us to create what we never could in the past. As the industry grows, a landscape designer’s pallet extends to the night as landscapes come alive with the pallet of Low Voltage Landscape Lights! Now that’s Innovation! Don’t miss out on the experience of creating a livable and stunning nighttime landscape. Check out the new tools that are becoming available today at your local landscape supply store.
