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.
Integral LED Lamps can be measured for Lumen Maintenance under IES LM-79-08. This can be a lengthy process - unless there is existing qualified LM-80 data, the test period lasts 6000 hours. Early Acceptance applications may be submitted after 3000 hours as long as there is existing, qualified LM-80 data and photometric test results that meet or exceed the standard.
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.
Current specification documents are ENERGY STAR Residential Light Fixture V4.2 and Solid State Lighting Luminaires V1.3. However the EPA has asked labs to stop using these as of Sept, 15th 2011. The new Luminaires Version 1.1 specification went into effect April 1, 2012. These are specifications which fall under the general Luminaire Program Requirements v1.1. Directional and non-directional luminaires have many different requirements. It is very important to know which category of luminaire will be tested .
Not covered by ENERGY STAR Luminaires v1.1: Outdoor lighting (e.g. commercial street and area, wall packs, canopy), high bay, recessed troffers or other types employed for general office illumination, adapters or converters.
Option 1 (Component Performance): if using LED packages / modules or arrays 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), and must meet all three of the conditions below:
The luminaires pass the Lumen Maintenance requirement if:
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 94.1% at 6,000 hours (residential outdoor and all non-residential) when operated in situ.
For non-directional luminaires, LED light engines, or Integral Lamps using the new GU24 standard socket, 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 94.1% at 6,000 hours (residential outdoor and all non-residential) when operated in situ.
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.
