Luminus Breaks the $0.10 per mW Barrier for UVC LEDs

Luminus Devices launched its newest UVC LED, the XBT-3535, with performance ranging from 50 mW to 80 mW in the 275-285 nm range. With the global need for disinfection and sterilization devices increasing, the price-performance combination of the XBT-3535 will allow companies to quickly bring novel and affordable solutions to market.

The germicidal effectiveness of UVC LEDs against E-coli, MRSA and a variety of pathogens has been well documented. UVC LEDs with wavelengths less than 280 nm are shown to be as or more effective than mercury lamps for disinfection and sterilization. However, performance, cost, and lifetime have been, in some combination, the factors slowing adoption of UVC LEDs.

Luminus addressed that the new products have median lifetime of over 10,000 hours under normal operation. Featuring increased power output, these UVC LED devices minimize the number of LEDs used in disinfection systems, and pricing in volume has been reduced to a level below US$0.10/mW. These factors make the large-scale deployment of UVC LEDs practical and accelerates the phase out of mercury lamps.
