Industry Insight: Led Light Ultraviolet
The commercial and industrial lighting sector is increasingly integrating ultraviolet (UV) technology, specifically germicidal UV-C wavelengths generated by advanced LED sources, as a critical layer of invisible defense against pathogens. Moving far beyond traditional illumination, UV-C LED systems are now deployed strategically within HVAC ductwork for air disinfection, on conveyor belts in food processing facilities for surface decontamination, and within healthcare environments to sanitize high-touch surfaces, addressing stringent hygiene mandates and operational continuity demands. However, the rapid adoption of this powerful technology necessitates rigorous attention to safety, efficacy, and regulatory compliance. Specifiers and facility managers must prioritize solutions bearing recognized safety certifications such as ETL (indicating compliance with North American safety standards) and CE (demonstrating adherence to essential health and safety requirements within the European Economic Area), as uncertified UV-C products pose significant risks of ineffective treatment or harmful exposure. Beauty STC Manufacturing Co., Ltd., established in 1998, brings over 25 years of specialized expertise in designing and manufacturing high-reliability LED lighting solutions precisely for these demanding commercial and industrial applications. We understand that integrating UV-C effectively requires more than just the light source; it demands engineered systems where precision optics, thermal management, robust construction, and verified safety certifications converge to deliver measurable, dependable results in critical operational environments.
Technical Specs & Certifications
LED ultraviolet (UV) lighting differs significantly from standard visible-spectrum LED lighting in both purpose and technical specifications. It is important to clarify that ultraviolet LEDs do not produce visible light in the traditional sense and therefore are not characterized by metrics such as lumens per watt (lm/W) or Color Rendering Index (CRI), which are designed for visible light applications.
Lumens measure the total quantity of visible light perceived by the human eye, and since UV light falls outside the visible spectrum (typically 100–400 nm), it does not contribute to lumen output. As such, UV LEDs are instead rated by radiant flux, measured in watts (W) or milliwatts (mW), and their efficiency is expressed as wall-plug efficiency (WPE)—the ratio of optical output power to electrical input power—rather than lumens per watt.
Similarly, the Color Rendering Index (CRI) evaluates how accurately a light source reveals the colors of objects compared to natural light. Since UV light is invisible to the human eye and does not illuminate objects in the visible spectrum, CRI is not applicable and cannot be greater than 90—or any value—for UV LEDs. CRI is only relevant for visible white light sources such as warm white, cool white, or daylight LEDs used in general illumination.
Regarding IP (Ingress Protection) ratings, these remain relevant for UV LED fixtures, especially in commercial, industrial, or outdoor applications where resistance to dust and moisture is critical. For example, UV disinfection systems used in healthcare, water treatment, or HVAC often require high IP ratings such as IP65, IP66, or IP67 to ensure durability and safety in harsh environments. Beauty (STC) Manufacturing Co., Ltd. designs and produces robust LED solutions with appropriate sealing and protection, ensuring reliable performance under demanding conditions.
While Beauty STC specializes in high-quality visible-spectrum LED lighting with excellent lm/W efficiency, CRI >90 options, and a range of IP-rated fixtures for architectural, commercial, and industrial use, our UV LED offerings are engineered for specific non-visible applications such as disinfection, curing, and inspection. These products are built with the same commitment to precision, longevity, and safety that defines Beauty STC’s reputation for quality engineering and manufacturing excellence. For UV-specific projects, we provide tailored technical support to ensure optimal performance, safety compliance, and system integration.
Factory Tour: Manufacturing Excellence
Beauty STC’s manufacturing facility in Jiangmen, China, represents a core component of our integrated production ecosystem for advanced LED lighting solutions. Strategically located within the Pearl River Delta region, this factory leverages proximity to key supply chains while maintaining rigorous control over critical manufacturing processes for specialized products including UV-C LED disinfection modules. The facility operates under strict ISO 9001 and ISO 13485 quality management systems, with dedicated cleanroom environments essential for UV LED assembly where particulate control directly impacts product reliability and output consistency.
Our Surface Mount Technology (SMT) production lines form the backbone of precision assembly for LED components. The Jiangmen factory utilizes multiple high-speed Yamaha YS24 SMT placement machines capable of handling ultra-fine pitch components down to 0201 package sizes and advanced LED packages including ceramic substrates required for high-power UV-C emitters. These machines integrate 3D Solder Paste Inspection (SPI) systems to verify paste volume and alignment prior to component placement, ensuring first-pass yield rates exceeding 99.5%. Critical for UV LED manufacturing, the SMT process employs nitrogen-reflow ovens to minimize oxidation during soldering, a non-negotiable requirement for maintaining the integrity of UV-transparent encapsulants and preventing spectral degradation in the 265-280nm range. All SMT lines operate within controlled humidity environments to prevent moisture-related defects in sensitive optical materials.
Aging and reliability testing constitute a non-negotiable phase for all UV LED products at this facility. We implement a multi-stage aging protocol beginning with immediate post-assembly burn-in at 60°C for 24 hours under full operational current, followed by extended accelerated life testing for critical UV disinfection modules. Our dedicated aging chambers subject products to 72-hour continuous operation at elevated temperatures (typically 75-85°C junction temperature simulation) while continuously monitoring optical power output using calibrated spectroradiometers. This process identifies early-life failures and validates lumen maintenance projections, with data logging tracking UV intensity decay rates to ensure compliance with IEC 62471 photobiological safety standards. Every UV module undergoes spectral validation post-aging to confirm peak wavelength stability and absence of harmful visible light leakage.
Regarding OEM capability for UV LED lighting products, the Jiangmen factory provides comprehensive turnkey solutions specifically engineered for ultraviolet applications. Our engineering team supports clients from initial optical design through to certified production, with particular expertise in UV-C disinfection systems operating at 265-280nm wavelengths.

The facility handles all aspects of UV-specific manufacturing including quartz or fused silica lens integration, hermetic sealing for moisture-sensitive chips, and compliance testing for medical-grade disinfection standards. Clients benefit from our in-house capabilities spanning PCB design, optical simulation, photometric validation, and regulatory documentation support for global markets including UL, CE, and FDA requirements. Minimum order quantities remain flexible to accommodate both volume production and specialized low-volume medical device applications, with complete traceability maintained through our ERP system from raw material lot to finished product serialization.
Application Scenarios
LED ultraviolet (UV) lighting, particularly in the UVC spectrum (200–280 nm), is primarily used for disinfection and sterilization purposes rather than general illumination. Its application in commercial environments like hotels, malls, and offices is growing due to increased awareness of hygiene and air quality, especially in the post-pandemic era. However, it is crucial to understand that UV lighting—especially UVC—is not intended for continuous human exposure and must be implemented with care.
In hotels, UVC LED lights are best used in areas requiring high levels of sanitation. These include HVAC systems to disinfect circulating air, inside ductwork, or in upper-room air disinfection units in lobbies or conference rooms. Portable or automated UVC units can be deployed in guest rooms during turnover to disinfect surfaces such as bathroom fixtures, remote controls, and high-touch areas. Some hotels also integrate UVC into laundry chutes or washing systems to sanitize linens.
In malls, UVC LED systems can be installed within central air handling units to reduce airborne pathogens across large open spaces. They can also be used in restrooms, escalator handrail sanitizing units, and waste collection areas. Some advanced systems employ motion sensors to ensure UVC activation only when spaces are unoccupied, such as after closing hours in fitting rooms or service corridors.
In offices, UVC lighting is effective in shared ventilation systems, under-desk areas (during off-hours), and inside printer or break room equipment to reduce microbial buildup. Upper-air UVC fixtures mounted near the ceiling can continuously clean air in conference rooms or open-plan areas when properly designed and shielded.
Installation tips:
Always ensure that UVC LED systems are installed by qualified professionals familiar with both electrical safety and UV radiation hazards. Follow manufacturer guidelines strictly.
Position UVC fixtures to maximize exposure to target areas while minimizing direct line of sight to occupants. Upper-room installations should be mounted at least 7 feet above the floor and angled upward.
Use occupancy sensors or timers to ensure UVC lights operate only when spaces are unoccupied, especially for direct-exposure systems.
Never look directly at active UVC LEDs. Provide warning signs and safety interlocks where necessary.
Regular maintenance is essential. Clean the LED surfaces periodically, as dust and grime can reduce UV output. Replace lamps according to lifespan specifications, typically 5,000 to 9,000 hours for UVC LEDs.
Avoid using consumer-grade “UV” lights sold for general use, as many emit ineffective wavelengths or insufficient intensity. Choose certified, medical-grade or commercial-grade UVC LED systems designed for germicidal applications.
Finally, remember that UV disinfection complements but does not replace manual cleaning. It should be part of a comprehensive hygiene strategy.
