Cree has expanded its CR series to include full definition CR4 and CR6 downlights to replace incandescent 4- and 6-in. recessed downlights. Featuring a warm-white 2700K color temperature, dimming and better than 80 CRI, the LED downlights use 20 to 30 percent less energy than CFLs. The CR4 delivers up to 575 lumens and the CR6 up to 625 lumens. Both are dimmable to 5 percent.
