Technical Specs & Certifications
Ultraviolet LED light bulbs operate outside the visible spectrum, fundamentally altering how we evaluate their performance compared to standard visible-light LEDs. It is critical to clarify that lumens per watt (lm/W) and Color Rendering Index (CRI) are metrics exclusive to visible light. Lumens measure perceived brightness by the human eye, which cannot detect ultraviolet radiation. CRI specifically assesses how accurately a light source renders colors within the visible spectrum relative to a reference source; since UV light is invisible, CRI is inherently undefined and irrelevant for UV LED products. Requesting CRI >90 for a UV source is a technical impossibility. Attempting to apply these visible-light metrics to UV LEDs stems from a common misconception but reflects a misunderstanding of photometric principles.
For ultraviolet LED systems, the relevant performance specifications shift entirely to radiometric and application-specific parameters. Key metrics include radiant flux measured in watts (W), irradiance in watts per square meter (W/m²) at a specified distance, peak wavelength in nanometers (nm) defining the UV band (UVA 315-400nm, UVB 280-315nm, UVC 100-280nm), and wall-plug efficiency expressed as radiant efficiency (optical watts out per electrical watt in). Spectral purity and output stability over the rated lifetime are also paramount. Beauty STC rigorously characterizes all UV LED products using calibrated spectroradiometers to ensure precise wavelength targeting and consistent radiant output, critical for applications like disinfection, curing, or counterfeit detection. Our engineering focus is on maximizing radiant efficiency and long-term spectral stability, not visible-light metrics which do not apply.
Regarding ingress protection, IP ratings remain highly relevant for UV LED fixtures or integrated bulbs designed for specific environments. Beauty STC UV products commonly achieve IP65 (dust-tight and protected against low-pressure water jets) for industrial curing stations or outdoor disinfection units, or IP67 (dust-tight and withstands temporary immersion) for specialized applications requiring higher environmental resilience. The IP rating applies to the complete luminaire or bulb assembly, not the bare LED chip, and is determined through standardized testing of the housing, seals, and electrical interfaces. We select robust materials like high-purity quartz glass for UVC transmission and aluminum housings with precision-machined gasket channels to maintain these ratings under operational thermal cycling and environmental stress.
Beauty STC’s quality assurance for UV LED products is built on stringent material science and manufacturing controls. We utilize high-transmission synthetic quartz substrates resistant to solarization under UVC exposure, critical for maintaining output over time. Our thermal management systems, featuring aluminum nitride ceramic substrates and optimized heat sinks, prevent wavelength drift and lumen depreciation common in poorly cooled UV LEDs. Every production batch undergoes 100% burn-in testing and spectral verification against A-grade reference standards, with full traceability through our ISO 9001-certified production lines. This commitment ensures our UV LEDs deliver the specified radiant intensity and wavelength accuracy required for mission-critical applications, distinguishing Beauty STC through reliability where performance deviations can compromise entire processes. We prioritize engineering integrity over misapplied visible-light specifications, providing clients with technically accurate and application-optimized UV solutions.

Application Scenarios
Ultraviolet LED light bulbs specifically designed for germicidal applications (UV-C, typically 265-275nm wavelength) are not standard “bulbs” intended for general illumination and must be used with extreme caution. They are engineered disinfection devices, not replacements for visible light sources. Their application in hotels, malls, and offices is strictly limited to targeted disinfection scenarios where human exposure is impossible during operation, adhering to stringent safety standards like IEC 62471. Misuse poses severe risks of skin burns and permanent eye damage. Never install UV-C LEDs in standard light fixtures accessible to occupants.
In hotels, germicidal UV-C LED systems have highly controlled applications. Upper-room air disinfection units, professionally installed high on walls above 2.4 meters, can treat air in lobbies, waiting areas, or staff break rooms with adequate air mixing, ensuring no direct exposure to occupants below. In-room disinfection is only feasible via specialized robotic units operated by trained staff after guest checkout, never via fixed “bulbs” left in fixtures. HVAC duct systems may incorporate UV-C LEDs near cooling coils to prevent microbial growth, requiring professional integration by qualified technicians. Surface disinfection of high-touch items like plastic keycards is possible in dedicated, interlocked cabinets operated only by staff.
Malls present significant challenges for UV-C deployment due to constant public presence. The primary viable application is within the HVAC system, targeting cooling coils and drain pans to maintain efficiency and air quality, installed by HVAC professionals during maintenance shutdowns. Restroom exhaust ducts might utilize UV-C for localized air treatment, but only if designed to prevent any UV leakage into occupied spaces. Open mall areas, fitting rooms, food courts, or escalator handrails are absolutely unsuitable for UV-C disinfection due to the unavoidable risk of public exposure. Any installation must be fully shielded, interlocked, and inaccessible during operation.
Offices offer limited opportunities. Upper-room UV-C fixtures could be considered in large conference rooms or training spaces used infrequently, installed high on walls with strict occupancy sensors and timers ensuring operation only when unoccupied. HVAC duct disinfection remains a primary application. Small, dedicated disinfection cabinets for shared items like headsets or tools, featuring safety interlocks that cut power when opened, are practical. Desks, workstations, or open-plan offices are entirely inappropriate locations for UV-C due to proximity to occupants and the impossibility of guaranteeing zero exposure.
Critical installation considerations override location specifics. UV-C disinfection systems must always be installed by qualified professionals with expertise in UV radiation safety and electrical systems. Full shielding is non-negotiable; fixtures must prevent any direct line-of-sight exposure to UV-C radiation in occupied spaces. Hardwired safety interlocks connected to room occupancy sensors or door switches are mandatory, instantly deactivating the system if a space becomes occupied. Strict adherence to manufacturer specifications for mounting height, spacing, and exposure duration is essential for efficacy and safety. Warning labels compliant with IEC 60417-6047 must be prominently displayed. Regular maintenance and output verification using calibrated UV-C meters are required, as lamp intensity degrades over time. Crucially, never retrofit UV-C LEDs into standard screw-in or pin-base sockets intended for visible light; these are specialized integrated systems, not interchangeable bulbs. Ozone generation must be verified as negligible, as some UV wavelengths produce harmful ozone. Always prioritize safer alternatives like enhanced filtration or targeted chemical disinfection where UV-C risks cannot be rigorously mitigated.
