HE-Series UV-C LED: High-Performance Disinfection Technology for Water, Air, and Surfaces

CrayoNano's newly launched HE-Series (CLH1-N3S) UV-C LED is our next evolution UV-C LED designed to meet the growing global demand for reliable, price-effective, and sustainable Mercury-free and energy efficient disinfection processes and solutions.

The HE-Series offers tailored solutions for precision disinfection, including options for:

  • 275 nm UV-C LEDs: Ideal for effective pathogen inactivation across various applications.
  • 265 nm UV-C LEDs (launching in Q2 2025): Providing enhanced disinfection efficiency for more demanding requirements.

With a focus on wavelength optimization, the HE-Series maximizes disinfection results while maintaining energy efficiency and sustainability.

Key Features of the HE-Series (CLH1-N3S)

  • Powerful Germicidal Efficacy

    Engineered to target a broad spectrum of pathogens, choose from 275 nm and 265 nm wavelengths to align with your application needs, ensuring reliable and effective performance.

  • Optimized Design for Seamless Integration

    Compact mechanical dimensions tailored for easy integration into existing systems.

  • Innovative Material Composition

    High-quality, thermally conductive composite substrates material (Copper and Ceramic based, ~400 W/m·K) for superior durability and performance.

  • Stable, Reliable UV-C Photon Output

    With an L70 lifetime of ~15,000 hours at 350 mA (Ta=60°C), our UV-C LEDs ensure long-lasting reliability and low total cost of ownership. Achieve high efficiency and stable performance at 500 mA+ with effective thermal management.

  • Our Sales and Customer Operations team are happy to assist you with your request. Please fill our contact form HERE, and our team will get back you as soon as possible.

  • Yes, our CrayoLED™ is RoHS and REACH compliant. We are committed to upholding the highest standards of environmental responsibility and sustainability. The certificates can be found on our FILES page.

  • 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 3,000 hours at 350 mA and more than 3,000 hours at 500 mA and 700 mA, with a solder temperature of 38 °C.

  • 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™.

  • 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 key difference between the H-Series and HE-Series CrayoLED™ lies in their level of optimization and application flexibility. 

    Generally, the mechanical dimensions and substrate material compositions of the two series differ, catering to diverse integration needs. 


    • Both LEDs feature a peak wavelength of 275 nm, a compact 3.5 x 3.5 mm footprint for seamless integration, a broad 120° beam angle, and are constructed using UV-C-optimized materials, including durable ceramic and high-quality UV-C transparent quartz glass.


    The H-Series is designed for reliable, general-purpose disinfection with a peak wavelength of 275 nm, making it ideal for a wide range of water, air, and surface disinfection applications.


    The HE-Series, offers advanced customization with options for 275 nm and a forthcoming 265 nm wavelength (launching in Q2 2025), allowing for precise optimization to meet specific disinfection requirements while maintaining superior performance and efficiency.

    Our team of LED experts are available to answer your questions and provide guidance on which LED will be suited for your application. Please contact our support team at support@crayonano.com for further assistance.
