CrayoNano AS Releases CrayoLEDTM CLH-N3S Lifetime Results >10,000 Hours Based on TM-21

TRONDHEIM, Norway—14 December 2022—CrayoNano releases the preliminary results of the CrayoLED^TM CLH-N3S H-Series UV-C LED Room Temperature Operating Life (RTOL) test conducted by an independent, accredited third-party testing and qualification lab.

The lifetime testing aims to demonstrate the quality and reliability of the CrayoLED^TM and generate data to predict the LED’s lifetime until it reaches 70 % of its original power output based on the TM-21 modeling. The RTOL testing follows the EIAJ-ED-4701/100(101) standard, an industry accepted test method to measure output power maintenance of LED packages. The CrayoLED^TM CLH-N3S LEDs are tested at the standard forward driving current, 350 mA per LED, under continuous operation for a minimum of 6,000 hours. The test condition and set-up consist of the CLH-N3S LED mounted on an Aluminum Metal Core Printed Circuit Board (MCPCB), attached to an Aluminum heatsink for thermal management, and running inside a temperature-controlled chamber.

CrayoNano has demonstrated after 3,000 hours (approximately 4 months), our CLH-N3S UV-C LED at 350 mA has maintained an average performance output of 79.3 %. This preliminary test data is extrapolated based on the TM-21 model and predicts an estimated lifetime of more than 10,000 hours. This unprecedented lifetime in a small footprint, high-power density UV-C LED will enable solutions in challenging applications requiring better performance and where maintenance is difficult— reducing our customers’ total cost of ownership. The corroborated data reinforce our customers’ confidence in CrayoNano’s CrayoLED^TM quality, robustness, and reliability for an efficient design-in and product qualification processes. The CrayoLED^TM is available immediately from stock for sampling and volume quantities.

“We have taken great care in creating the CrayoLED^TM —optimizing our LED package design and assembly technology using higher quality materials, combined with our understanding of the thermal efficiencies and performance of LEDs,” says our Chief Product Officer, Alejandro Basauri.

The CrayoLED^TM is a market leading high-power UV-C LED with compact footprint, offering the highest power density with a 10,000 hour lifetime. It is optimized for disinfection with a typical peak wavelength of 275 nm. Its small package footprint (3.5 mm x 3.5 mm) and high-power performance (typical 80 mW optical power at 350 mA) easily integrates into systems for residential, commercial, and industrial segments, enabling system miniaturization and longer lasting solutions.

CrayoNano will continue testing until the results have reached 6,000 hours to complete the TM-21 testing criteria. Alejandro Basauri continues, “We are immensely proud of the results. Quality and reliability are key factors for solutions towards automated disinfection solutions.”
