LED FAQ & Resources Guide

LED Lighting Programs

CSA Group Seattle is a NVLAP ISO 17025 accredited laboratory dedicated to providing LED testing and measurement services and products. There is a great deal of confusion in the LED testing and measurement market. Many customers are curious about which types of tests are needed for their LED devices, from LEDs to Luminaires and Lamps. We’ve combed the documents provided by the U.S. Environmental Protection Agency’s ENERGY STAR® program to create this LED Testing FAQ to answer our customers most frequent questions about test, measurement, and ENERGY STAR® certification.

LED Testing FAQ

If you have an LED product that does not fall into one of the ENERGY STAR® categories, it likely falls under a DLC category. Give us a call at 425-605-8500 and we can help you figure out which one applies to your product.

Integral LED Lamp Certification

CSA Group Seattle provides Integral LED Lamps certification. There is a new specification document, ENERGY STAR Solid State Lighting Luminaires V2.1, effective October 1, 2017. All products tested under older specifications will lose their ENERGY STAR certification status on September 30, 2017. For the most up-to-date specifications, visit ENERGY STAR.

ENERGY STAR Lamps V1.1 scope is limited to lamps with integrated ballasts and drivers intended to be connected to the electric power grid with the following ANSI standard base types:

  • E26
  • E26d
  • E17
  • E11
  • E12
  • GU24
  • GU5.3
  • GX5.3

The scope is also limited to lamps with rated nominal operating voltages of 120, 240 or 277 VAC, or 12 or 24 VAC or VDC.

Integral LED Lamp Certification are the result of measuring output for Lumen Maintenance under IES LM-80-08. This can be a lengthy process as the test period lasts 6000 hours. Early Acceptance applications may be submitted after 3000 hours if there is qualified LM-80 data and ISTMT test results for the LEDs used in the lamp that meet or exceed the standard.

The CSA Group Seattle LED test & measuring laboratory is fully equipped and certified under ISO 17025 to perform IES LM-80-08 or IES LM-79-08 measurements needed for a customer to submit a report to an ENERGY STAR Certification Body (CB). CSA Group, Orb Optronix’ parent organization is a current ENERGY STAR CB.

Luminaire & Light Fixture Certification

CSA Group Seattle provides Luminaire & Light Fixture Certification. The current specification documents for ENERGY STAR Luminaires Version 2.0 went into effect June 1, 2016. Directional and non-directional luminaires have many different requirements. It is very important to know which category of luminaire will be tested.

ENERGY STAR Luminaires v1.2 mainly covers residential grade luminaires. It also includes some commercial grade luminaires such as:

  • accent lights
  • downlights (excluding troffers or linear forms)
  • under cabinet task lighting
  • portable desk task lights
  • separable or inseparable SSL luminaires

A few classes of commercial grade lighting are specifically not covered:

  • outdoor lighting (e.g. commercial street and area, wall packs, canopy)
  • high bay
  • recessed troffers or other types employed of general office illumination
  • adapters
  • converters

Luminaire Lumen Maintenance Qualification

CSA Group Seattle provides Lumen Maintenance Qualification. Option 1 (Component Performance): if using LED packages / modules or arrays including those incorporated into LED light engines or GU24-based integrated LED lamps which have passed IES LM-80-08 testing then the applicant must demonstrate that those LED operate at or below the LM-80 tested temperatures when operated in situ (that is, under normal operating conditions). This is done with an ISTM test (ISTMT).
The LM-80 tested LEDs used must meet the following L70(6k) rated lumen maintenance life values, in situ:

  • L70(6k) ≥ 25,000 hours for residential indoor
  • L70(6k) ≥ 35,000 hours for residential outdoor or commercial

The L70(6k) compliance must be documented with a TM-21 lumen maintenance life projection report.

The luminaire passes the Lumen Maintenance Qualification requirement, if:

  • In the sample luminaire, the in situ TMP LED temperature is less than or equal to the temperature specified in the LM-80 test report for the corresponding or higher drive current, within the manufacturer’s specified operating current range.
  • The drive current measured in the luminaire is less than or equal to the drive current specified in the LM-80 test report at the corresponding temperature or higher.
  • The TM-21 lumen maintenance life projection report projects an L70 meeting or exceeding requirements.

Option 2 (Luminaire Performance):

For directional luminaires the applicant demonstrates compliance with the lumen maintenance requirement by submitting an LM‐79 photometric test data report for the entire luminaire, comparing initial output (time = 0 hours) to output after 6,000 hours of operation (time ≥ 6,000 hours) (when operating in accordance with UL 1598-2008).

The test report must demonstrate an L70 lumen maintenance of at least 91.8% at 6,000 hours (residential indoor) or at least 94.1% at 6,000 hours (residential outdoor and all non-residential) when operated in situ.

For non-directional luminaires, LED light engines, or GU24-based Integral LED Lamps, the applicant demonstrates compliance with the lumen maintenance requirement by submitting LM-82 test data, comparing initial output (time = 0 hours) to output after 6,000 hours of operation (time ≥ 6,000 hours) (when operating in accordance with UL 1598-2008).

During initial and final LM-82 measurements, Tb temperature shall be controlled to match Tb temperature measured when source is operated in situ.

The test report must demonstrate an L70 lumen maintenance of at least 91.8% at 6,000 hours (residential indoor) or at least 94.1% at 6,000 hours (residential outdoor and all non-residential) when operated in situ.

What is TM-21?

TM-21 is a calculation which extrapolates previously collected LM-80 data to predict the extended effects on a given device over time. TM-21 is available for review at www.energystar.gov. Energystar.gov also offers a TM-21 calculating spreadsheet.

Mark Hodap, Senior Application Engineer at Philips Lumileds released a U.S. Department of Energy power point deck in 2011 explaining TM-21:

TM-21 What it is, and why it is important

  • IESNA TM-21 (Technical Memorandum) specifies how to extrapolate the
    LM-80-08 lumen maintenance data to times beyond the LM-80 test time.
    For example: EPA ENERGY STAR® Manufacturer’s Guide requires L70 of
    25,000 or 35,000 hours.
  • TM-21 is important because it is referenced in the EPA ENERGY STAR
    Guides, and customers generally are concerned about getting ENERGY
    STAR approvals for their products.
  • It is also important as it creates a common playing field for LED competitors
    to specify lumen maintenance behavior for their white LED products
    intended for illumination applications.

What Is DesignLights Consortium (DLC)?

A large variety of LED lamps and luminaires are covered under the ENERGY STAR lighting program, but they don’t have all products. The DLC (DesignLights Consortium) runs the Qualified Product List (QPL) that is similar to ENERGY STAR but covers commercial products. It has quality and performance standards that are required to put products on the list. The list is used by utilities, states and regional energy efficiency programs in the U.S. and Canada. The performance standards and testing required are very similar to those for ENERGY STAR.

LED Lighting Programs Regulation And Resources Guide

How do I submit data to ENERGY STAR®?

ENERGY STAR is the voluntary labeling program administered by the US Environmental Protection Agency (EPA). Since 1992, ENERGY STAR has been guiding consumers toward products that are more energy efficient. As technology changes, ENERGY STAR revisits its requirements.

CSA Group Seattle provides EPA-recognized laboratory reports that are ready to be submitted to an ENERGY STAR Certification Body (CB) for approval.

ENERGY STAR provides guidance for LM-80 Lumen Maintenance Testing.

What is the LED Lighting Facts® Label Program?

The LED Lighting Facts Label is a program provided by the U.S. Department of Energy. The label is printed on the packaging of new LED-based lighting products and provides an easy-to-read summary with visual representations of overall energy efficiency measures such as Light Output, Watts, Efficacy, CRI, and CCT on any participating LED Lighting Product. These measurements must be taken by an accredited lab and manufacturers must take the Lighting Facts pledge to use the label. Orb Optronix is qualified to produce reports that meet the DOE requirements for the LED Lighting Facts program.

What is the DesignLights Consortium® Program?

The DesignLights Consortium (DLC) program was created to ensure that LED based lighting for commercial applications meets high-quality, high-performance standards through testing and verification by accredited labs like CSA Group Seattle Seattle. Tested products that are accepted to the DesignLights Consortium Qualified Products List are eligible for rebates and other incentives.

What is the California Energy Commission Title 24?

The California Energy Commission has specific energy conservation requirements within Title 24 of the State’s Building Better Efficiency Standards. Most of these requirements are for the assistance of sign manufacturers who must demonstrate compliance with Title 24.

What is Joint Appendix 8 (JA8)?

Joint Appendix 8 is an appendix to CEC Title 24 which went into effect January 1 2017.  It is the only standard currently which address flicker.  It is more restrictive then the energy star standards for lighting.

CSA Seattle is a 17025 NVLAP accredited lighting laboratory which has also been approved by the California Energy Commission to test solid state lighting products to the new 2017 Joint Appendix 8 (JA8) lighting performance requirements.
