Philips Lumileds' new LUXEON 3535 2D has the highest efficiency in its class

LUXEON 3535 2D, which combines two LED chips in a package to enable reduction in LED count and cost of designing retrofit lamps, consumer downlights and diffuse industrial lamps. Best-in-class efficacy of 140 lm/W is achieved for cool white light at 4000K and minimum 80 CRI.

“This is an exciting breakthrough, because lighting designers can take advantage of a high lumen package with high efficacy while using significantly fewer chips per fixture,” said Rahul Bammi, VP of Product Management at Philips Lumileds. “For example, a 50W PAR20 lamp can be achieved using only 4 LEDs. Alternatively, a 40W A19 lamp that previously required 14 LEDs can now be created using only 6.”

The new mid-power LEDs are offered across a full spectrum of correlated color temperatures (2700K-6500K) with a minimum CRI of 80. Versions with CRI 70 for outdoor applications and CRI 90 for high end indoor applications are planned for future release.

The LUXEON 3535 2D line operates at 0.5 – 1W, delivering up to 130 lumen in the compact 3535 form factor. Rated at 100mA, the LUXEON 3535 2D can be driven up to a maximum of 200mA. The LUXEON 3535 2D supports ENERGY STAR® certification requirements up to 25,000 hours at 85°C and 150mA.
