The ENERGY STAR Lamps Specification V1.0 was finalized on August 28, 2013. To continue labeling products with the ENERGY STAR logo, all existing qualified lamps must be re-qualified by an EPA-accredited certification body to the new specification by September 30, 2014. This presentation gives you a thorough understanding of the key changes, scope and deadlines for compliance with the new specifications.

Timeline for Compliance
• Final version effective September 30, 2014
By this date, if lamps are not recertified to Lamps V1.0, they could
be taken off the ENERGY STAR website.
• Historically, ENERGY STAR program administrators tend to close off
submissions to old version ~9 months prior to effective date, to
enable all stakeholders to prepare for new requirements.
• Intertek Recommendation:
Partners or laboratories should not be testing to previous
versions as of December 2013 / January 2014.

Common Definitions – Omnidirectional
OLD
CFL categories = “bare” or
“covered”
NEW
Lamp that distributes light evenly
in all directions =
“omnidirectional”

Note:
common
type of CFL
9. www.intertek.com9
Common Definitions – Directional
OLD
CFL categories = “indoor
reflectors” or “outdoor
reflectors”.
NEW
Lamp that distributes light
primarily in one direction =
“directional”.

10. www.intertek.com10
Common Definitions
– Directional for PARs and MRs
OLD
• CFLs = N/A
• LEDs = confusion about
restrictions on beam angle in
definition and center beam tool.
NEW
• All standard Parabolic
Aluminum Reflector (PAR) and
MR lamps (either source) must
have at least 80% light output
with a solid angle corresponding
to a cone with an angle of 120°
(= 60° zone).
11. www.intertek.com11
Common Definitions – Decorative
• A lamp with a candle-like or globe-like shape or lamps with
purely decorative outside envelopes.
o Note: may include those with A–shaped envelopes also, or
lamps with candelabra bases.
(picture credit – Osram Sylvania)
12. www.intertek.com12
Common Definitions – Reported
• In layman’s terms, “reported” = “rated”.
• May be ratings that appear on packaging and/or marketing
materials.
• Per ENERGY STAR Directive 2011-05, reported values shall not be
more efficient than measured.
o “Efficient” defined as “Efficacy” = Lumens per Watt
13. www.intertek.com13
Common Definitions – CFLS covered by DOE
Regulations
• CFLS covered by DOE’s regulatory program = CFLs with
medium screwbases that are not reflectors or 3-ways.
• When testing to federal regulations* (EPACT, etc.) testing
must be performed by NVLAP accredited lab.
• Mostly comes into play with ratings (efficacy, lifetime,
rounding, calculations, etc.).
* Refers to 10 CFR Part 430 Appendix W to subpart B, which refers to Energy Star V2.0.
14. www.intertek.com14
Common Definitions – Standard Lamp
• A “standard” lamp is an incandescent lamp whose dimensional outlines
appear in an ANSI standard.
• Ex: A-lines, PARs, Rs, Globes, Candles, etc.
• Often known as the “replacement lamp” the energy efficient lamp is
replacing.
• Energy efficient lamps must declare a standard lamp equivalent. The
dimensions of the energy efficient lamp must fit inside the ANSI
dimensional outline for
• Overall Length - Min and Max (OAL and MOL) (includes base)
• Maximum Diameter values (where they exist)
• Decorative: within +/- 15% of nominal diameter if no ANSI outline exists
15. www.intertek.com15
Common Definitions – Certification Points
• “Early Interim” certification point refers to the earliest point a lamp
can be certified to carry the ENERGY STAR mark.
o For CFLs, this is at 4,000 hours (real-time)
o For LEDs, this is at 3,000 hours (real-time)
• “Full” certification point refers to the minimum point a lamp can fully
be certified to carry the ENERGY STAR mark. This point may be
longer for higher life ratings than minimums below.
o For CFLs, this is at 10,000 hours (real-time)
o For LEDs, this is at 6,000 hours (real-time, = 15K or 25K rated,
depending on LED category)
3,000 hrs LED
4,000 hrs CFL
10,000 hrs CFL
15,000 –
25,000 hrs LED
16. www.intertek.com16
Common Definitions – Temperature Restricted
• Lamps that are “temperature restricted” are:
o Omnidirectional lamps that are labeled “not for use in
enclosed fixtures” on the lamp and lamp packaging (or
similar language).
o Any lamps that are labeled “not for use in recessed
fixtures” on the lamp and lamp packaging (or similar
language).
• Critical to know this rating up front for life testing
temperatures.
17. www.intertek.com17
Common Definitions – Position Restricted
• Lamps that are “position restricted” are:
o Lamps that are only intended to operate in certain
positions (ex: base up, etc.).
o Lamps that are tested in Life Test Apparatus Option A or
Option B
Must indicate test position on packaging (or similar
language).
• Critical to know this rating up front for life testing apparatus.
18. www.intertek.com18
Common Definitions – Distribution
• Distribution testing captures both the intensity
of the light output and at the angle the light is
coming from.
• The intensity of light is measured in the unit
“candelas”.
• These candelas are grouped into vertical
“zones” and lumens are calculated using
formulas.

Biggest Test Changes – Distribution
OLD
•N/A for CFLs
•Required for LED
Directional and
Omnidirectional
NEW
• Required for all LED lamps
and CFLs** of PAR and MR
shapes
• CFLs omnidirectional and
decorative exempt
• Some directional lamps
have pass/fail criteria and
some are just to set up for
a different test such as
color-spatial uniformity.
**Lamps V1.0 states in section 9.5 that CFLs are exempt from the Luminous Intensity Distribution requirements.
However, all PAR and MR lamps (regardless of source type) are required to comply with 9.4 - Center Beam
Intensity, and this comes from a distribution test.

Dimming Note
There is a confusing note on page 19 of Lamps V1.0
that reads:
“For purposes of third-party certification, maximum lighting output, minimum lamp
output, flicker and noise levels shall be reported by the partner to the certification body
however documentation shall not be reviewed when products are certified or during
verification testing. “
On 9/19/13, the EPA clarified this to mean that the dimming data
can come from the partner (aka: first party) as long as it complied
with all the data required in the related sections. Certification Bodies
(CB) are to report this data, and only passing data will be accepted.
40. www.intertek.com40
Family Grouping – Allowable Variations
• Representative model and variant(s) must demonstrate correlation
as follows:
1. Input current and input wattage ± 10%
2. Power factor ± 5%
3. Maximum overall length (base changes not included) ± 5%
4. Maximum overall diameter ± 5%
5. Safety listing report includes descriptions of both variant and
representative model demonstrating identical construction
(except for allowed variations)
6. For LED lamps, average in situ temperature(s) of variants shall
be no higher than 2.5°C from representative model

In Summary
• As soon as possible, contact your certified body for a “Technical
Review” to sort family groupings and see what data will transfer to the
new Lamps V1.0 specification.
• Some new tests will be likely, and at a minimum, your product might
need to undergo the following tests:
o CFL Lamps:
New Lumen Maintenance and Life Testing if previously rated < 10,000 hours (or
omnidirectional lamp category may fall into elevated temperature category)
New Rapid Cycle Stress Test
Distribution Test for Directional lamps
New Dimming Tests (if rated)
o LED Lamps:
Distribution for Omnidirectional and Decorative categories
New Rapid Cycle Stress Test
New Dimming Tests (if rated)
Note: each CB will
determine
acceptance of
older data
