 Higher level of maintenance to the Facility Manager
» Status of lamp and ballast
 Greater flexibility to the Lighting Designer
» Change grouping via software
 Lower energy costs to the User
» Reduced power consumption
 Greater sense of control to the Occupant
» Individual control

Benefits for architects
 Ability to Mix and match
» All major manufacturers offer DALI-compliant lighting control devices which are
available for all kinds of light sources – offering freedom of choice
» Architects can combine lighting solutions from multiple manufacturers and use
different types of luminaires in one installation, allowing more artistic freedom

 Scene-based lighting
» Using different lighting scenes, the mood and function of rooms or areas of a
building, or even the character of a building itself, can be changed at the touch
of a button

 Meeting people’s needs
» Good lighting meets the visual, emotional and biological needs of the people
using a building
» Optimum conditions can be created by means of automated dimming and
switching, using daylight and occupancy sensors, for example

Source: DALI-AG

Benefits for specifiers
 Cost-effective
» Fewer components and simple wiring, systems offer intelligent scene-based lighting management at low cost
» Luminaires are grouped using software instead of hard-wiring allows changes to be made at any point up to the
commissioning stage purely by reprogramming, without the expense of redesigning or rewiring
 Versatile
» Replaces inflexible 1-10V analogue systems
» Control individual luminaires, light groups and networks
» Luminaires can be freely assigned to different groups to create flexible lighting scenes for workplaces, rooms, floors and
buildings
» Interoperable with all building management systems
» Lighting scenes can be configured, reconfigured, saved and called up again on a central computer, meeting changing
requirements with total flexibility throughout the system’s life
 Simple and intelligent
» Single interface for all types of electronic control gear (ECG) and lighting control devices
» Light fittings from any manufacturer and of any load type can be used in one installation, as long as they are fitted with
DALI ECG, removing the constraints created by proprietary systems
» Local lighting intelligence of the ECG, fewer controls are necessary for changing lighting scenes and even first-time
users can quickly learn to operate groups of lights

Benefits for installers and electrical contractors
 DALI is not only easy to install, but also extremely cost effective, saving both time and resources

 Wiring made simple
» Single-cable digital system
» Wiring is done using only a standard mains rated 5-core cable that handles power supply and DALI
communications, so no separate bus cable or special tools are required
» Offers complete freedom of topology, DALI avoids the wiring errors common with 1-10V systems
 Digital means simple and flexible
» There is no need to wire luminaires in groups
» The system is simply programmed and, if requirements change, it can be reprogrammed, thus avoiding
costly rewiring
» Switching relays are unnecessary because switching is done locally by the ballasts themselves
» DALI can easily be integrated into a building management system by means of a simple gateway
interface
» Testing, fault-finding and commissioning are simplified and time is saved thanks to central monitoring of
luminaire status

Source: DALI-AG

Benefits for building owners and facility managers

More Crestron GLB-DALI Ballast Product Details
 Digital Addressable Lighting Interface (DALI)
The DALI (Digital Addressable Lighting Interface) standard allows multiple ballasts to be
daisy chained using low-voltage wiring for power on/off and dimming control. Up to 64
ballasts can exist on a single DALI channel, each operating independently. DALI lighting is
optimal for applications that require granular control of each fixture, such as open office floor
plans and daylight harvesting in classrooms.

 Build-in Power Metering
Optional power metering tracks real time energy usage of each load, thereby delivering
statistics to help control energy costs. By analyzing real data, organizations can make
educated decisions regarding energy resources, which will have greater impact on the
bottom line.

 Protection
GLB-DALI ballasts feature End-of-Life Protection, are short and open circuit proof and have
an auto shutdown feature in case of lamp failure. GLB-DALI ballasts are feature protected
shut down against main input lower than 80 Volts AC and auto recovery starting from 95
Volts AC. GLB-DALI ballasts also feature warm start in every dimming position and overload
protection.
