The LEDs deliver up to 931 lumens at 85 degrees Celsius and 13 percent 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 LEDs enable 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 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 degrees Celsius.
The LEDs are available from Mouser Electronics in colour temperatures ranging from 2700K to 5000K and color rendering indexes (CRI) of 70, 80, and 90.
