LED maker Lumileds LLC of San Jose, CA, USA has introduced the LUXEON 2835 HE, which achieves luminous efficacy of over 200lm/W while providing high color consistency.

Expanding on the LUXEON 2835 Line, the new LED is optimized to deliver high efficacy and 2-step MacAdam ellipse color consistency in applications such as troffers and high-bay/low-bay fixtures. “The LED’s tight color point distinguishes it from other mid-power devices in its class,” says Sam Wu, product manager of Mid Power Products. “Design kits to 2-step MacAdam ellipse are available for the ultimate in color consistency for demanding lighting applications,” he adds. The LED delivers luminous flux of 36lm at 65mA drive current and 202lm/W, or 220lm when driven at 480mA (4000K and 80 CRI).

“LUXEON 2835 HE is ideally suited to troffers, downlights and lamps where fixture efficacy greater than 150 lumen per watt is paramount and LED count must be minimized,” says Wu. Lumileds says that its high-reliability design enables the LUXEON 2835 HE to deliver more light for smaller-profile, general lighting applications. Unlike many 2835 LED packages on the market, it is lumen-maintenance tested (LM-80) to 12,000 hours, ensuring lumen maintenance of 72,000 hours in the field (L70, TM-21 basis).

The LUXEON 2835 HE is available in a wide range of color temperatures and color rendering indexes (CRIs) of 70-90 to address a variety of general lighting designs. The LED is available immediately as a drop-in replacement for 2835 LED packages (2.8mm x 3.5mm) or can replace 5630 (5.6mm x 3.0mm) or 3030 (3.0mm x 3.0mm) mid-power sockets with similar optical requirements.
