A.L.P. LexaLite® Announces LM-79 Capability
Niles, IL. – Aug. 18, 2010 – The experts on A.L.P. Lighting Components, Inc.’s LexaLite® brand engineering team are now performing absolute goniophotometry per the requirements of LM-79. This testing, conducted in the company’s Charlevoix, MI facility, includes efficacy (lumens per watt) as well as traditional distribution and intensity measurements. In cooperation with another local lab, it can also address the color requirements of LM-79 (CRI and CCT).
While today only LED fixtures are subject to the LM-79 protocol, some experts already perceive the benefits of testing induction and linear fluorescent fixtures using absolute photometry as well. Any light source that is subject to significant variations in lumen output between ambient and operating temperatures can be tested using absolute photometry. Absolute photometry eliminates misleading fixture efficiency results from temperature sensitive lamps by providing the comparable metric of lumens per watt. An example is a T5 fluorescent fixture that may show efficiency near 90 percent, when perhaps 15 percent of this is the thermal effect of the lamp putting out 15 percent more lumens at operating temperature versus ambient temperature.
