143 lumens per watt from new LED

New XP-E2 LEDs provide about a 20% boost in brightness compared to the older XP-E devices they are meant to replace. Developed by Cree Inc., they are rated to provide up to 128 lm/W at 350 mA, 85°C or 143 lm/W at 350mA, 25°C in cool white (6,000K).

The LEDs are built using Cree's SC3 technology which uses a silicon carbide base. The XP-E2 LEDs use the same XP footprint (3.45 x 3.45 mm) and are optically compatible with all XP LED designs, including XP-E and XP-G LEDs.

The XP-E2 LEDs target high-lumen applications that range from indoor and outdoor lighting to portable and lamp retrofits. Cree says luminaire makers seeking Energy Star qualification will have access to specification and performance data, including LM-80 reports. XP-E2 LEDs succeed the original XP-E LED for LM-80 data – accelerating qualification of luminaires using just 3000 hours of LM-80 data, instead of the normal 6,000 hours.

Cree XLamp XP-E2 LED samples are available now and production quantities are available with standard lead times. XP-E2 LEDs are available in 2,700K to 7,000K color temperatures with minimum CRI options of 70, 80, 85 and 90.
