The Illuminating Engineering Society of North American (IES) has issued a new document: IES Approved Method for the Characterization of LED Light Engines and LED Lamps for Electrical and Photometric Properties as a Function of Temperature, LM-82-12.
The purpose of the document is to establish consistent methods of testing and data presentation for ease of interpretation and comparison, which will assist luminaire manufacturers in selecting suitable LED light engines and integrated LED lamps for each luminaire product.
This approved laboratory method defines the procedures to quantify the performance of LED light engines and integrated LED lamps as a function of temperature. LM-82-12 is listed at $25 ($17.50 for members). Click here to learn more.
