Crystal IS Announces Improvements to its Klaran® Line of Germicidal UVC LEDs to Provide 20% Higher Performance and Lower Cost

In addition to its existing Klaran 60 mW UVC LED, Crystal IS is adding a 70 mW UVC LED for immediate production use and an 80 mW engineering sample to its WD Series. All devices will take advantage of in-house production improvements which lower forward voltage and result in a tighter wavelength specification of 260 nm to 270 nm – the ideal germicidal range. Klaran WD Series devices will be priced under 15 cents per mW with supply agreement.

“The completed production and technology improvements fulfill the promise of Crystal IS’ proprietary Aluminum Nitride substrates- high yields of high output devices at deep UV wavelengths” said Eoin Connolly, VP, Product Management. “Klaran continues to focus and achieve key milestones which allow us to deliver the products, performance and price needed to meet the needs of global germicidal markets. Our rigorous testing, in-house microbiological facilities and ISO 9001:2015 quality system provide the data-driven proof of the reliability, performance and efficacy of our products.”

“The research by NEIDL at Boston University demonstrates that SARS-CoV-2 can be effectively inactivated in a matter of seconds through exposure to low doses of UVC light in the key germicidal range” said Larry Felton, President at Crystal IS. However, comparing test results from this study against published results from the University of Miyazaki (which used UVC LEDs emitting at 280 nm) highlights a marked drop in efficacy beyond 270 nm wavelength. While there is much to be done in the fight against the coronavirus pandemic, Crystal IS believes this type of data can be used to help design innovative and effective disinfection solutions.

Klaran UVC LEDs are currently being used by a number of partners, including Healthe AirTM by Healthe, Inc., and Big Ass Fans Clean Air System Haiku with UV-C, which provides continuous disinfection and clean airflow in retail, restaurant, fitness and office settings.
