LED lowers system costs to meet DLC 4.0
Claimed to deliver lower system costs for high lumen, high efficiency applications designed to meet the new DesignLights Consortium (DLC) 4.0 Premium requirements, the XLamp MHB-B LED uses key elements of Cree’s SC5 technology.
The ceramic LEDs combine high light output, high efficacy and high reliability to enable high lumen LED designs that are not possible with mid-power LEDs. It delivers up to 931lumens at 85 degree C and 13 per cent higher LPW than the MHB-A LED in the same 5.0 x 5.0mm package. This allows lighting manufacturers to increase performance for existing designs without any additional investment.
It enables designs that use significantly lighter and smaller heatsinks than designs based on mid-power LEDs, says the company. For example, a high-bay reference design built with the LEDs delivers 24,000lumens and more than 130LPW system efficacy at 44 per cent less weight and 36 per cent smaller diameter than comparable high bays based on mid-power LEDs. They have LM-80 data available immediately, delivering reported L90 lifetime projections of 60,000 hours at 105 degree C. The reference design demonstrates a cost-effective way to meet all of the DLC 4.0 Premium requirements for high bay luminaires.
The LEDs are available in 2,700 to -6,500K with high CRI and multiple voltage options. Product samples are available now, and production quantities are available with standard lead times.
