  • 3. www.intertek.com3 Our Heritage Caleb Brett founds a marine surveying business 1885 Thomas Edison establishes what is later renamed as the Electrical Testing Laboratories (ETL) 1896 Virginius Daniel Moody establishes Moody Engineering for construction and electrical engineering projects 1911 Intertek and Moody International join forces 2011 Intertek Today: Valued Quality. Delivered. Today
  • 4. www.intertek.com4 An Extensive Global Network • FTSE 100 company in the Support Services sector • Market capitalization at £5 billion • Revenue generation of over £1.7bn in 2012 100 More than countries 1,000 More than laboratories and offices 33,000+ people
  • 5. www.intertek.com5 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.
  • 6. www.intertek.com6 Included Products • In layman’s terms, products included in Lamps V1.0 are lamps that are intended to replace incandescent lamps. • Lamps contain integrated ballasts or drivers (Multifaceted Reflector (MR)-16 exempt). • Lamps intended to connect to common electrical grid: o 120, 240, or 277 Vac o 12, 24 Vac or Vdc • Includes lamps with following ANSI standard base types:  E26, E26D, E17, E11, E12, GU24, GU5.3, GX5.3 E26 E17 E11 GU24 GU5.3 “medium screwbase” “intermediate base” “candelabra base” “heavy 2 pin” “light 2 pin”
  • 7. www.intertek.com7 Excluded Products • Lamps that operate only on external power sources. • Linear LED tubes intended to replace fluorescent tubes. • Lamps not intended to tie in to electrical grid (i.e. solar only, battery only). • Lamps with bases not covered in ANSI standards and base types not listed on page 1 of Lamps V1.0. • Lamps incorporating power-consuming features which do not provide illumination (ex: audio, air fresheners).
  • 8. www.intertek.com8 Common Definitions – Omnidirectional OLD CFL categories = “bare” or “covered” NEW Lamp that distributes light evenly in all directions = “omnidirectional” (picture credit – Osram Sylvania and Rambus) 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”. (picture credit – Maxlite)
  • 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. (graphic credit IES LM-79)
  • 19. www.intertek.com19 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.
  • 20. www.intertek.com20 Distribution – Omnidirectional OLD • N/A for CFLs • Required for LED Omnidirectional • Candelas shall not differ from the mean by more than 20% in 0°–135° zone NEW • N/A for omnidirectional CFLs • Required for omnidirectional LED lamps • In same 0°–135° zone: 90% of the candelas shall not differ from the average by more than 25% and no single point shall vary by more than 50% • Vertical angles at 5° maximum • 5% or more lumens shall be emitted in 135°–180° zone
  • 21. www.intertek.com21 Distribution Graphic – Omnidirectional see page 24 of Lamps V1.0 – graphic credit EPA
  • 22. www.intertek.com22 Distribution – Decorative OLD N/A NEW • N/A for decorative CFLs • Required for all decorative LED lamps • No less than 5% of lumens shall be emitted in the 110°–180° zone • Includes globes
  • 23. www.intertek.com23 Distribution Graphic – Decorative (see page 24 of Lamps V1.0) – graphic credit EPA
  • 24. www.intertek.com24 Distribution – Directional OLD • N/A for CFLs • N/A for LED R, BR, ER, and K types. • Required for LED PARs and MR-16 lamps – used ENERGY STAR Center Beam Tool to calculate minimum required candelas. NEW • Required for all PARs and MR-16 lamps – uses ENERGY STAR Center Beam Tool to calculate minimum required candelas. • No requirements on zonal lumens (though there are some requirements in directional definition). • Needed as a pre-test for Color Angular Uniformity for other LED Directional lamps.
  • 25. www.intertek.com25 Biggest Test Changes – Rapid Cycles Stress Testing – CFLs OLD • CFLs: 6 samples • One cycle = 5-minutes- on, 5-minutes-off • Total number of cycles = ½ of rated life • 5 out of 6 samples must survive NEW • CFLs: 6 samples • One cycle = 5-minutes-on, 5- minutes-off. • For CFLs with a start time of ≤100 ms, total number of cycles = ½ of rated life, 5 out of 6 must survive • Others: total number of cycles = same as rated life or 15,000 cycles max, 5 out of 6 samples must survive
  • 26. www.intertek.com26 Biggest Test Changes – Rapid Cycles Stress Testing – LEDs OLD • LEDs: 10 samples • One cycle = 2- minutes-on, 2- minutes-off • Total number of cycles = ½ of rated L70 life • 9 out of 10 samples must survive NEW • LEDs: 6 samples • One cycle = choice of 2- minutes-on, 2-minutes-off or 5-minutes-on, 5- minutes-off • Total number of cycles = same as rated life or 15,000 cycles max • 5 out of 6 samples must survive
  • 27. www.intertek.com27 Life Test Temperatures – 25°C nominal • Lamps that are tested in nominal* 25°C ambient are: o Decorative lamps o Omnidirectional lamps < 10 W o Any lamps that are “temperature restricted” *CFLs tolerance on 25C = 15-40°C , LEDs tolerance on 25°C = 20-35°C
  • 28. www.intertek.com28 Biggest Test Changes – Elevated Temperature Life Testing OLD • For CFLs: only required for indoor reflectors • For LEDs: only required for directional and omnidirectional category ≥ 10W NEW • Required for all Omnidirectional lamps ≥ 10 W and all Directional lamps (any wattage) • Exempt: products that are “temperature restricted”
  • 29. www.intertek.com29 Option A – Elevated Temperature Life Testing – Recessed ICAT Cans • Self heating. • For omnidirectional lamps ≥ 10 W or directional lamps (any wattage). • For lamps with “position restriction” on packaging. • Sample size = 10 lamps base up.

  • 32. www.intertek.com32 Biggest Test Changes – Elevated Light Output Ratio OLD Required for indoor reflector CFLS only NEW • Required for all directional lamps that are not temperature restricted • Lamp shall maintain ≥ 90% of initial light output at 25°C ± 5°C when tested in elevated life temps • Can use Option A or B life apparatus, sphere, other equipment. Example: if at 25C lumens = 1000, at elevated temp, lumens ≥ 900 to pass
  • 33. www.intertek.com33 Biggest Test Changes – Color Angular Uniformity OLD • N/A for CFLs • LED Directional Lamps: o 2 horizontal planes 90° apart o 10° vertical increments o Quit at beam edge (=50% of center candelas) NEW • N/A for CFLs • LED Directional Lamps: o 2 horizontal planes 90° apart o 2° maximum vertical increments for beam angles < 15° o 5° maximum vertical increments for beam angles ≥ 15° o Continue over complete distribution pattern
  • 34. www.intertek.com34 Biggest Test Changes – Dimming Testing OLD • N/A for CFLs • Involved in Operating Frequency test only for LEDs NEW • All lamps rated or marked as dimmable • Maximum and Minimum Light Output on Dimmer • Noise on Dimmer • Flicker on Dimmer
  • 35. www.intertek.com35 Dimming Testing – Dimmer Sample Sizes • For lamps designed for phase cut dimming (alternations to the line voltage to the lamp): o 5 dimmers o From at least 2 different manufacturers o Representing various construction or consumer conditions o Ex: pre-set levels, forward-phase, reverse phase, rated 200W, rated 600W, etc. • For lamps designed for non-phase cut dimming: o Tested with all compatible dimmers listed on packaging o Packaging must include “*” and point to an “only compatible with…” statement
  • 36. www.intertek.com36 Dimming Testing – Other Information • Lamps are tested with 1 lamp as load and again with 4 lamps as load • 80% of tested lamp/dimmer combinations must pass • Dimming at maximum setting on a dimmer shall not drop more than 20% light output when operated without a dimmer • Dimming at minimum setting on a dimmer shall be no higher than 20% light output when operated at maximum dimming • Highest percent flicker and highest flicker index shall be reported • Noise shall not be above 24 dBA at 1 meter or less during dimming Ex: Baseline (no dimmer) = 1000 Lumens High Dim ≥ 800 Lumens to pass Low Dim ≤ (High Dim Lumens * 0.20) Lumens to pass
  • 37. www.intertek.com37 Dimming Tests – Visual Matrix – Most common dimmer configuration (phase cut) = 63 new tests Lamp No. Baseline (no dimmer) Dimmer #1 Dimmer #2 Dimmer #3 Dimmer #4 Dimmer #5 1 Light Output High Dim High Dim High Dim High Dim High Dim 1 Low Dim Low Dim Low Dim Low Dim Low Dim 1 + 3 lamp load High Dim High Dim High Dim High Dim High Dim 1 + 3 lamp load Low Dim Low Dim Low Dim Low Dim Low Dim 1 Flicker High Dim Flicker High Dim Flicker High Dim Flicker High Dim Flicker High Dim Flicker 1 Low Dim Flicker Low Dim Flicker Low Dim Flicker Low Dim Flicker Low Dim Flicker 1 + 3 lamp load High Dim Flicker High Dim Flicker High Dim Flicker High Dim Flicker High Dim Flicker 1 + 3 lamp load Low Dim Flicker Low Dim Flicker Low Dim Flicker Low Dim Flicker Low Dim Flicker 1 Noise High Dim Noise High Dim Noise High Dim Noise High Dim Noise High Dim Noise 1 Low Dim Noise Low Dim Noise Low Dim Noise Low Dim Noise Low Dim Noise 1 + 3 lamp load High Dim Noise High Dim Noise High Dim Noise High Dim Noise High Dim Noise 1 + 3 lamp load Low Dim Noise Low Dim Noise Low Dim Noise Low Dim Noise Low Dim Noise
  • 38. www.intertek.com38 What is Flicker? Flicker is a visible modulation of light output
  • 39. www.intertek.com39 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 see page 7 of Lamps V1.0 for more details
  • 41. www.intertek.com41 Family Grouping – Allowable variations Attribute Allowable Variation Additional Test Data Required for Variant Correlated Color Temperature (CCT) • Allowed to share data where only variation is phosphor • Representative model completes lumen maintenance and life testing • Efficacy • Lumens • Elevated Temp Light Output Ratio (if applicable) • Center Beam Intensity (if applicable) • Distribution (if applicable) • CCT, CRI • Color Angular Uniformity (if applicable) • Run-Up Time (CFLs only) see page 7 of Lamps V1.0 for more details
  • 42. www.intertek.com42 Family Grouping – Allowable Variations Attribute Allowable Variation Additional Test Data Required for Variant LED: Heat Sink Paint Color Lamp body color pigment (not type of paint or plastic) N/A LED: Beam Angle Allowed if beam angle varies due to secondary optics - changes in material not allowed • Distribution Data • Center Beam Intensity • Color Angular Uniformity Lamp Base (ANSI) Allowed N/A Decorative only: Envelope Shape Allowed as long as material and thickness is unchanged N/A Decorative only: Envelope Finish Allowed so long as material and thickness is unchanged • Lumen Efficacy • Lumens • CCT, CRI see page 7 of Lamps V1.0 for more details
  • 43. www.intertek.com43 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
