Cree LED launches record-efficacy 228lm/W high-power LED

Cree LED Inc of Durham, NC, USA (a company of SMART Global Holdings of Milpitas, CA) has launched J Series 5050C E Class LEDs, which have what is claimed to be the industry’s highest efficacy for high-power LEDs of 228 lumens per watt (LPW) typical at 4000K, 70 CRI (color rendering index) and 1W.

The new J Series LEDs deliver what is reckoned to be up to three times the light output of competing 5050 LEDs at the same efficacy level. The LEDs are also designed with what is claimed to be superior corrosion resistance for the most challenging environments.

With the addition of the new E Class LEDs, Cree LED now offers four performance levels in the J Series 5050 LED portfolio to address most directional general lighting applications. Unlike other 5050s with asymmetric die layouts that reduce intensity through secondary optics, J Series 5050 LEDs feature optimized layouts that deliver peak intensities up to 12.5% higher than the competition, it is reckoned, as well as improved color-over-angle.

“The breakthrough performance of 5050C E Class LEDs enables substantial system cost savings through the reduction in optics, PCBs and chassis material. Up to 40% system cost savings and 57% reduction in size are possible when redesigning from a lower-performance 5050 LED to the 5050C E Class LED,” says David Peoples, VP of marketing. “To speed up the design-in process, 5050C E Class LEDs are compatible with optics designed for existing square LES [light-emitting surface] 5050 LEDs.”

Suitable for outdoor area, high/low-bay, roadway and indoor professional applications, the new 5050C E Class LEDs are available in 2200–6500K correlated color temperatures (CCTs) as well as 70, 80 and 90 CRI options for all CCTs.

Product samples are available now and production quantities are available with standard lead times.
