CrayoNano UV-C LEDs reach 100mW and 5% efficiency


UV-C LED is a "game changer in the disinfection market"

Norwegian start-up CrayoNano has announced a performance improvement of its CrayoLED H-series UV-C LED. Entering the class of 100 mW, 5 percent wall-plug efficiency at a standard operating current of 350 mA, this LED is said by the company to be a game changer in the disinfection market.

“Our dedication to continuous development and commitment to quality and performance has culminated in more than 30 percent improvement since the product’s launch. Entering the performance class of 100 mW, 5 percent wall plug efficiency, high drive current capacity without compromising our values of quality first—make the CrayoLED a reliable, efficient, and robust solution, ideal to enable mass UV-C LED adoption into disinfection applications,” says Michael Peil, CRO. “With these results, we look forward to further characterisation of our LEDs at a higher drive current capacity.

The improved wall plug efficiency of 5 percent means that the LED is not only more energy-efficient and generates less heat, but has a longer lifetime. The CrayoLED has a L70, TM-21 extrapolated lifetime of more than 10,000 hours at 350 mA, a defining industry required standard.

The CrayoLED would have an effective lifespan of up to 5-10 years in commercial and residential Point-of-Use (POU) and Point-of-Entry (POE) water disinfection systems. These systems typically use UV-C LEDs for several minutes per operation cycle, for a total annual usage of approximately 1,000-2,000 hours. The CrayoLED provides a reliable and long-lasting solution for water disinfection.

The long lifetime and high-power output of 100 mW reduce the need for frequent replacement, facilitating the adoption of UV-C LED disinfection in municipal water treatment facilities. These facilities require reliable and powerful solutions to handle higher water flows and reduce maintenance needs. The combination of the CrayoLED’s UV-C LED longevity and performance makes it an efficient and effective solution for water treatment applications.

CrayoLED H-series (CLH-N3S) is available in both sample quantities and in stock for volume production.
