CrayoLED™ is a powerful UV-C LED in the class of 100 mW, 5 % wall-plug efficiency and 275 nm peak wavelength at 350 mA. The small package footprint easily integrates into disinfection, curing, and analytical applications.

Our CrayoLED™ is a UV-C LED designed to disinfect and meet the high standards of disinfection applications, with a powerful virucidal output at 275 nm. Using TM-21 modeling, we have extrapolated an L70 lifetime of over 10,000 hours at 350 mA with a solder temperature of 38 °C. The CrayoLED™ UV-C LED is a highly reliable, efficient and sustainable solution, ideal for fast-growing disinfection applications. 

The CrayoLED™ is more than a powerful UV-C LED but extremely robust and reliable when operated beyond our standard conditions. The CrayoLED’s high drive current capacity offers performance and flexibility for our customers without sacrificing quality or lifetime as substantiated by externally confirmed results from an accredited third-party test lab. 

Overall, the CrayoLED™ is an exceptional product that combines powerful disinfecting capabilities with high output power and wall-plug efficiency. It is designed to meet the needs of our customers' applications and provide a reliable, long-lasting performance to contribute to the global challenges we are facing today towards a sustainable and healthier future for everyone.


High performance and quality

The core design principles of our CrayoLED™ is the use of high-quality materials ideal for UV-C LED applications. We collaborate and understand our customers' needs for performance and reliability. Our LED utilizes an Aluminium Nitride (AlN) substrate for its excellent thermal properties, a built-in ESD protection device, and UV-C transparent quartz glass.


Enabling new applications

We have all experienced the need for better water, air, and surface applications. CrayoLED™ constant, pure UV output at 275 nm (typical peak wavelength), is ideal for disinfection applications.  It enables better and more sustainable solutions to accelerate the adoption of UV-C LED disinfection.

  • The total system design—thermal management, power design, and module design—directly contributes and effects the UV-C LED product lifetime.

    Using TM-21 modeling, we have extrapolated an L70 lifetime of over 10,000 hours at standard operating conditions. In our testing, the CrayoLED™ running continuously for over 6,000 hours at 350 mA and more than 3,000 hours at 500 mA, with a solder temperature of 38 °C. We will continue this testing until 6,000 hours or until it reaches 70 % of the original output power (L70).

    Our industry experts are available for technical support and assistance, reach out to us through our Contact Form.

  • Our LEDs are measured using a pulsed forward current of 350 mA, then are binned and sorted by peak wavelength, output power, and forward voltage. Our bin tables can be found in our datasheet.

  • The CrayoLED™ has a nominal driving current of 350 mA and a maximum driving current of 500 mA. Running LEDs at their maximum values will have an effect on the overall performance and lifetime. Product performance and reliability depends on the overall system design—including (but not limited to) thermal management, optical design, and assembly processes and materials.

    In our testing, the CrayoLED™ has been running continuously for over 6,000 hours at 350 mA and more than 3,000 hours at 500 mA, with a solder temperature of just 37.8 °C. This performance highlights the robustness and reliability of the CrayoLED™.

  • We are happy to share with you the ray files for the CrayoLED™ H-series (CLH-N3S). Due to the large file size, please contact our support team at for further assistance.

  • Our commitment to continuous improvement on performance and quality, and our efforts result in improved performance. Therefore to minimize the document versions, we have removed the typical power value on the datasheet. Please refer to our characterization tables and bin tables for product information.
