GREEN ISLAND, N.Y. & DÜSSELDORF, Germany & NEW YORK--(BUSINESS WIRE)--Asahi Kasei, a diversified Japanese multinational company, 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 lifetime1 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) (Figure A) 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 (Figure B), demonstrating the organization’s commitment to providing amble characterization data under various test conditions to aid in our customers’ designs. The VEKTREX system enables Crystal IS to perform lifetime testing of large quantities of LEDs at multiple temperatures and driving currents.
“Klaran LA's lifetime performance is the result of Asahi Kasei product innovation using the Crystal IS proprietary aluminum nitride substrate and reinforces the company mission to replace low-pressure mercury lamps in consumer and industrial applications that depend on reliable and effective disinfection performance,” said Eoin Connolly, President and Chief Executive Officer of Crystal IS. "We want the Crystal IS name to be synonymous with quality, reliability, and a commitment to real disinfection products that improve life and living around the world. Our rigorous testing on thousands of Klaran devices and ISO 9001 quality system provide the data-driven proof of the reliability and performance of our Klaran products."
1 L70 lifetime refers to the point in time when an LED produces 70% of its initial light output.
The Klaran product line leverages the unique properties of Crystal IS' Aluminum Nitride to provide premium germicidal UVC LEDs and associated modules to treat water, air, and surfaces for healthcare, consumer appliances, and commercial water treatment. As the leading choice for the world's top appliance and equipment manufacturers, Klaran offers an international, award-winning team of application engineers to provide hands-on support for prototyping, testing, and validating its UVC LED solutions.

About Crystal IS
Crystal IS, an Asahi Kasei company and ISO 9001:2015 certified, is a pioneer in developing and commercializing Aluminum Nitride substrates. Aluminum Nitride's wider bandgap capability means that devices grown on Aluminum Nitride can more effectively (technically and economically) emit at the deeper ultraviolet (UVC) wavelengths than devices grown on sapphire. As a result, Crystal IS products produce high-performance UVC LEDs for environmental monitoring and disinfection in various applications that enhance and sustain life and living worldwide.
