Asahi Kasei and subsidiary Crystal IS have released lifetime characterization data after more than 10,000 hours of testing its Klaran LA UVC LED, which supports a projected L70 lifetime of 25,000 hours. This advancement retains true disinfection with a refined wavelength optimal for germicidal efficiency, with a lifetime exceeding low pressure mercury lamp technology, promoting the transition to non-mercury/non-ozone generating devices. The characterization data on its Klaran LA UVC LEDs was released to assist partner companies in water, air, and surface treatment to take full advantage of its UVC LED capabilities in their designs.

This data shows how a set of Klaran LA LEDs operating with a Junction temperature of 53°C (soldering point temperature of 35°C) would have a projected L70 lifetime value over 25,000 hours. This data was observed on the Crystal IS in-house VEKTREX Integrated Thermal Control Systems, demonstrating the organization's commitment to providing amble characterization data under various test conditions to aid in customers' designs. The VEKTREX system enables Crystal IS to perform lifetime testing of large quantities of LEDs at multiple temperatures and driving currents.
