At LightFair, I enjoyed a product demo from Cree LED. Their booth emphasized their latest color LEDs, as well as their RGBW packages. The big splash was their recently released XLamp® Element G (XE-G) LEDs. The XE-G line includes 9 direct emission colors and 8 phosphor-converted (PC) colors. With 17 colors and a full portfolio of white options (6500K-2700K; 70-90 CRI), the new XLamp XE-G LED family delivers industry-leading output/efficiency, in a small form factor.
Equally interesting were the RGBW LEDs, the XLamp XM-L Color Gen 2 LEDs. They enable high output, up to 1,400 lumens, and color mixing for directional RGBW luminaires. The XM-Ls do all of this in a tiny 5.0 x 5.0 mm package. The XLamp XM-L Color Gen 2 LEDs feature the smallest possible distance between LED die, creating a small optical source for excellent optical control and efficient color mixing. Gen 2 also includes a new High-Intensity version that further reduces the optical source size for even greater levels of optical control.
