Studio T+L's Jason Livingston will be presenting Understanding and Applying TM-30 to the New Jersey section of the IES on Tuesday, March 19th. If you're interested in attending you can register at http://www.iesofnj.org/TM3015.html.
Like other lighting technologies, the color or chromaticity of light emitted by an LED can shift over time. To address the challenge of developing accurate lifetime claims, DOE, together with the Next Generation Lighting Industry Alliance, formed an industry working group, the LED Systems Reliability Consortium (LSRC). A new LSRC report, LED Luminaire Reliability: Impact of Color Shift, focuses on chromaticity. The purpose of the new report is not to define limits for specific applications, but rather to enable a better understanding of how and why color shifts, and how that impacts reliability. Download it and take a look.
