Orb Optronix, a trade name of the CSA Group

Orb Optronix is a NVLAP ISO 17025 accredited laboratory dedicated to providing LED test and measurement services and products. There is a great deal of confusion in the LED test 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 for answers to our customers most frequent questions about test, measurement, and ENERGY STAR® certification.

What do I need to do to certify my Integral LED Lamps (Light Bulbs) with ENERGY STAR?

What do I need to do to certify my Luminaires (Light Fixtures) for ENERGY STAR?

What are my options for Luminaire Lumen Maintenance Qualification?

What is TM-21?

What is DLC and do I need to be on their list?

What do I need to do to certify my Integral LED Lamps (Light Bulbs) with ENERGY STAR?

There is a new specification document, ENERGY STAR Lamps V1.0, that will take effect September 30, 2014. Testing of LED lamps may be done under the old specification, ENERGY STAR Integral LED Lamps V1.4, until May 30, 2014, but all products tested under the old specification will lose their ENERGY STAR certification status on September 30, 2014.

ENERGY STAR Lamps V1.0 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, and 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 Lamps can be measured for Lumen Maintenance under IES LM-79-08. 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 Orb Optronix 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.

What do I need to do to certify my Luminaires (Light Fixtures) for ENERGY STAR?

The current specification documents for ENERGY STAR Luminaires Version 1.2 went into effect December 21, 2012. 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 and 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, or converters.

What are my options for Luminaire 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 L70(6k) compliance must be documented with a TM-21 lumen maintenance life projection report.

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.

What is DLC and do I need to be on their list?

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.

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