Technical Specs & Certifications
LED UV light bulbs operate outside the visible spectrum and therefore do not produce lumens or possess a Color Rendering Index (CRI). Lumens quantify visible light output perceivable by the human eye, while CRI measures a light source’s ability to accurately render colors relative to a reference source, both of which are irrelevant for ultraviolet radiation. UV light is measured in terms of irradiance (typically microwatts per square centimeter, µW/cm²) at specific wavelengths (e.g., UVA 315-400 nm, UVB 280-315 nm, UVC 100-280 nm) and radiant flux (watts). Attempting to assign lumens or CRI values to genuine UV LED products is technically incorrect and misleading. For applications requiring high-quality visible light alongside UV functionality, such as certain counterfeit detection or mineralogy lamps, a dual-source design might incorporate a separate visible LED array. In such cases, the visible component could achieve >90 CRI and high lumens per watt, while the UV component remains specified by its radiant power and peak wavelength.
Regarding IP ratings, UV LED bulbs designed for demanding environments require robust ingress protection. Beauty STC rigorously tests its UV lighting solutions to appropriate IP standards based on the intended application. For industrial curing or outdoor disinfection fixtures, IP65 (dust-tight and protected against water jets) or IP67 (dust-tight and protected against temporary immersion) ratings are commonly achieved and verified through standardized testing protocols. Consumer-grade UV bulbs, like those for nail curing, typically target IP20 (basic protection against finger contact, no dust/water resistance) as they operate in controlled indoor settings. Beauty STC ensures all IP claims are validated through third-party laboratory testing, not merely design intent.
Beauty STC’s commitment to quality is paramount in UV LED manufacturing. We utilize high-binning UVC or UVA LEDs from Tier-1 semiconductor suppliers to ensure consistent spectral output and longevity. Our thermal management systems, featuring precision-engineered aluminum heat sinks and thermal interface materials, maintain junction temperatures well below critical thresholds, directly extending LED lifespan and stabilizing UV output – a critical factor where performance decay impacts efficacy. Each UV bulb undergoes 100% in-line testing for radiant flux, forward voltage, and beam pattern. For UVC disinfection products, we implement stringent biological validation protocols alongside radiometric calibration. Our ISO 9001-certified manufacturing processes include rigorous environmental stress screening, such as thermal cycling and humidity exposure tests, far exceeding basic industry requirements. This unwavering focus on material quality, thermal design, and comprehensive validation ensures Beauty STC UV LED bulbs deliver reliable, safe, and performance-consistent operation throughout their rated lifetime, meeting the exacting demands of professional and industrial applications.

Application Scenarios
LED UV light bulbs, specifically germicidal UV-C systems, serve distinct purposes in commercial environments but require precise application due to safety considerations. It is critical to clarify that standard LED “bulbs” emitting UV-C for disinfection are not typical consumer products; they are specialized fixtures requiring professional installation. True germicidal UV-C operates at 254nm and poses significant risks to skin and eyes, making them unsuitable for general illumination. Their use in hotels, malls, and offices is limited to targeted disinfection applications, not ambient lighting.
In hotels, germicidal UV-C systems are appropriate for HVAC ductwork to sanitize circulating air or within enclosed upper-room air disinfection units in lobbies or high-traffic corridors where continuous air cleaning is beneficial. Surface disinfection applications are highly restricted; they might be considered only in unoccupied spaces like vacant guest rooms using automated, timed systems with strict occupancy sensors and safety interlocks, but this is uncommon due to liability and practicality. Restroom disinfection via UV-C is generally impractical and unsafe in guest-accessible areas. For malls, the primary viable application is within the central HVAC system to treat air before distribution, particularly in large atriums or enclosed common areas. Surface disinfection of high-touch points like escalator handrails requires fully enclosed, interlocked systems that activate only when the handrail is within the shielded chamber and inaccessible to the public—open or exposed UV-C fixtures near shoppers are strictly prohibited. Offices may utilize upper-air UV-C fixtures in high-ceilinged meeting rooms or lobbies, mounted at least 2.4 meters high with louvers directing light upward, ensuring no direct exposure to occupants below. UV-C within office HVAC remains a standard application. Desktop “sanitizing boxes” using contained UV-C for small items like phones are acceptable if fully shielded and interlocked, but standalone bulbs for room disinfection are unsafe and ineffective in occupied offices.
Installation demands rigorous adherence to safety protocols. Always engage certified UV-C system specialists; this is not a DIY application. Fixtures must incorporate multiple redundant safety features: motion sensors that instantly cut power upon detection, physical key locks, and visible warning indicators. For upper-air systems, precise mounting height and tilt angles per ASHRAE guidelines are essential to prevent stray radiation. HVAC-integrated units require professional ductwork integration with UV-resistant materials and safety cut-offs. Never install UV-C where direct line-of-sight exposure to occupants is possible, even briefly. All installations must comply with IEC 62471 for photobiological safety and UL 8800 certification. Crucially, UV-C is supplementary to cleaning—it does not replace manual disinfection of soiled surfaces. Always verify local regulations, as many jurisdictions restrict UV-C use in public spaces. Beauty (STC) strongly advises against using consumer-grade “UV LED bulbs” marketed for disinfection; these often lack adequate UV-C output, safety certifications, and can create hazardous ozone. For any application, prioritize third-party tested systems with full safety documentation and professional commissioning.
