The XLamp XHP70.2 LEDs is the next generation of Extreme High Power LEDs that deliver the lowest system cost through the best lumen density, reliability and color consistency...

Leveraging key elements of Cree’s SC5 Technology Platform, the ceramic MHB-B LEDs combine high light output, high efficacy and high reliability to enable high lumen LED designs that are not possible with mid-power LEDs. The MHB-B LED delivers up to 931 lumens at 85°C and 13 percent higher LPW than the MHB-A LED in the same 5mm x 5mm package, allowing lighting manufacturers to quickly increase performance for existing MHB designs without any additional investment.

The MHB-B LED enables designs that use significantly lighter and smaller heat sinks than designs based on mid-power LEDs. For example, a high-bay reference design built with MHB-B LEDs delivers 24,000 lumens and more than 130 LPW system efficacy at 44 percent less weight and 36 percent smaller diameter than comparable high bays based on mid-power LEDs.

Built on Cree’s industry-leading high-power ceramic technology, the MHB-B LEDs have LM-80 data available immediately, delivering reported L90 lifetime projections of 60,000 hours at 105°C. The reference design demonstrates a cost-effective way to meet all of the DLC 4.0 Premium requirements for High Bay luminaires.
