Cree LED J Series® 2835 J-/N-Class Precision Dimming LEDs

Cree LED J Series® 2835 J-/N-Class Precision Dimming LEDs combine high efficacy and excellent value in a 2.8mm x 3.5mm x 0.7mm reliable package. The LEDs are optimized for low‑density lighting applications where high efficacy and smooth appearance are critical, such as downlights, troffers, and panel lights. Precision dimming provides a simplified approach to addressing the issue of unacceptable LED light output and hue variations when using low‑current dimming. Most solutions just control voltage, while Precision Dimming controls voltage and color rendering metrics, including CRI and TM-30 Rf.
