LED Color Stability: 10 Important Questions
This April 15, 2014 webinar examined the causes of color shift, and took a look at existing metrics used to describe color shift/color stability in LED lighting. The lumen maintenance lifetime of many LED products is 25,000 hours or more, but that doesn't mean products are guaranteed to perform the same over that time. One thing that could change is the color of the light, or chromaticity. Presenters Michael Royer of Pacific Northwest National Laboratory, Ralph Tuttle of Cree, and Chad Stalker of Philips Lighting answered questions concerning established tolerances for color shift, current standards that apply to the measurement of color shift, and plans for new methods and/or standards for projecting color shift in the future, among others.
