Cree Inc of Durham, NC, USA has introduced its XLamp XM-L2 LED, which delivers up to 186 lumens-per-watt at 350mA, 25°C. Built on Cree's SC3 Technology next-generation LED platform, which leverages the firm's silicon-carbide technology, XM-L2 LEDs double the lumens-per-dollar and deliver 20% more lumens-per-watt over the original XM-L LED, says the firm. The XM-L2 LED delivers 1198 lumens at 116 lumens-per-watt efficacy at 3A, 25°C.
Designed for very-high-lumen applications, such as indoor, high-bay and outdoor lighting, XM-L2 LEDs are compatible with existing XM-L LED designs and leverage the 5mm x 5mm XM footprint, which allows customers to incorporate the XM-L2 LEDs into existing XM LED designs.
"The XM-L2 LED efficiently delivers hundreds of lumens per LED, allowing us to significantly reduce the number of LEDs in our designs," said Steve Walczak, director of engineering, Sternberg Lighting. "By using fewer LEDs, we can simplify design and production, ultimately reducing cost without sacrificing light output or quality for our end customers."
Characterized at 85°C, the XM-L2 LED is available in 2700K to 6200K color temperatures and offers minimum CRI options of 80, 85 and 90. Additionally, since the XM-L2 LED is a successor product to XM-L LEDs, the application of ENERGY STAR qualification requires only 3000 hours of XM-L2 LED LM-80 data, instead of the normal 6000 hours. The XM-L2 LED is also UL-recognized and features a level-4 rating.
XLamp XM-L2 LED samples are available now, and production quantities are available with standard lead times.
