Lumileds

 

Lumileds announces the introduction of the LUXEON 2835 HE, which sets a new standard for efficacy in the mid-power LED market: the 4000K/80CRI variant achieves 202lm/W when producing 36lm at a drive current of 65mA.

The new LED, which extends the successful LUXEON 2835 line, is optimized for high color consistency as well as high efficacy. Color variation at the LED light source is limited to just a two-step MacAdam ellipse over the full operating-temperature range.

Lumileds’ high-reliability design also enables the LUXEON 2835 HE to be driven at high currents of up to 480mA, enabling lighting OEMs to produce a high light output from low-profile general lighting fixtures. At 480mA, the 4000K variant produces an output of 220lm.

Lumileds expects the LUXEON 2835 HE to be most popular in applications such as troffers and downlights, in which high efficacy is important and LED count must be minimized.

Unlike many 2835 LED packages on the market, the LUXEON 2835 HE is lumen-maintenance tested on the TM-21 basis to 12,000 hours, indicating L70 lumen maintenance of 72,000 hours in the field.

The new 28mm x 35mm LED is available immediately as a drop-in replacement for standard 2835 LED packages. It can also replace 5630 or 3030 mid-power sockets that have similar optical requirements to those of a 2835 LED.
