New high-power LEDs deliver lower system cost

Mouser now stocks the Cree XLamp MHB-B LEDs. These new high-power LEDs enable designers to more effectively deliver lower system costs for high-lumen, high-efficiency applications designed to meet the new DesignLights Consortium (DLC) 4.0 Premium requirements. The LEDs incorporate key elements of Cree's SC5 Technology platform to combine high light output, high efficacy and high reliability to enable high lumen LED designs that are not possible with mid-power LEDs. The LEDs deliver up to 931 lumens at 85C and 13% higher lumens per watt (LPW) than the MHB-A LED in the same 5mm × 5mm package, allowing lighting manufacturers to quickly increase performance for existing MHB designs without any additional investment. The 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 these LEDs delivers 24,000 lumens and more than 130 LPW system efficacy at 44% less weight and 36% smaller diameter than comparable high bays based on mid-power LEDs. Built on the company’s high-power ceramic technology, the LEDs have LM-80 data available immediately, delivering reported L90 lifetime projections of 60,000 hours at 105C. The LEDs are available in colour temperatures ranging from 2700K to 5000K and colour rendering indexes (CRI) of 70, 80, and 90.
