CSA Group Seattle’s Electrical Thermal Optical LED Characterization Service (ETO) provides complete Electrical-Thermal-Optical data over your choice of input electrical and thermal conditions. In order to design systems that utilize high power LEDs, the light output characteristics (color and flux) must be known as a function of temperature and electrical input characteristics. Users of this service then can make fundamental design decisions regarding LED selection, thermal management, luminous efficacy, and more. High power LED manufacturers are currently specifying optical output of their LEDs under short single current pulse conditions. Today’s high power LED specification sheets generally assume that the junction temperature is equal to the ambient air temperature of 25°C. Although these tests are easily repeatable, they are not particularly useful to engineers designing LEDs into illumination and display products. The decrease of luminous flux and shift in wavelength as temperature rises is highly variable and depends on the properties of LEDs. NIST’s Optical Technology Division (OTD) is conducting research to address this important issue and recommends LED characterization be performed under TEC Control. This information is necessary when designing robust LED-based products with specific desired light output and lifetime characteristics. LED integrators can now accurately and completely characterize the Electrical Thermal Optical properties of LEDs using CSA Group Seattle’s services to solve these complex product development challenges.

About LED Eye Safety Testing Can Light Emitting Diodes (LED’s) used in today’s consumer electronics cause eyestrain, headaches, and increased risk of eye damage? Research is increasingly proving these hazards to be of concern, which is why LED Eye Safety Testing is used to determine if there is a blue light hazard. Consumers are regularly exposed to narrow spectrums of intense LED light. This is especially true of white LEDs because they include more blue light emissions, making this is a concern for LED product manufacturers and consumers alike.

• SeriesCEC Title 24 Joint Appendix 8 (JA8) Testing

Title 24 2016 is California’s building energy efficiency standard. All lighting installations in new or existing buildings which require a building permit must be compliant to this standard. JA8 and JA10 are appendixes to Title 24 which specifically reference high efficiency lighting including LED lighting. In some cases JA8 and JA10 are more demanding than ENERGY STAR® standards. CSA Group Seattle is a 17025 NVLAP accredited lighting laboratory approved by the California Energy Commission to test solid state lighting products to the new 2017 Joint Appendix 8 (JA8) lighting performance requirements. We test and measure LED lighting luminaires and lamps to evaluate if they meet or exceed these and other requirements: Initial Efficacy of ≥ 45 lumensWatt Power Factor ≥ 0.90 Start time ≤ 0.5 sec Correlated Color Temperature (CCT) ≤ 4000 or 3000 Kelvin depending on luminaire type Duv of ≥-0.0033 and ≤ +0.0033 Color Rendering Index (CRI) ≥ 90 Color Rendering R9 (red) ≥ 50 Ambient or elevated temperature test for rated life, lumen maintenance, and survival rate (must have LM-80 data for LEDs) Rated Life ≥ 15, 000 hours Minimum dimming level ≤ 10% 6, 000 hour lumen maintenance ≥ 86.7%, or TM-21 Projected Time to L70 ≥ 25, 000 hours Dimming control compatibility – At least one type must be listed Flicker to JA10 – At least one type must be listed Audible Noise ≤ 24 dBA @ 100% and 20% light output – At least one type must be listed Marked in accordance with JA8.5 As part of your photometric performance test suite our CEC approved lab will prepare a Title 24 JA8 formatted report showing your performance compliance to all applicable JA8 and JA10 requirements. Passing lights can then be registered on the California Energy Commission (CEC) database by submitting report.
