Technical Specs & Certifications
Beauty STC Manufacturing Co., Ltd. provides high-performance UV-A LED lamps designed for industrial, scientific, and specialized applications such as curing, counterfeit detection, and fluorescence inspection. It is critical to address a fundamental technical point upfront: UV-A radiation (315-400 nm) falls outside the visible light spectrum. Consequently, standard photometric metrics like lumens (which measure perceived brightness by the human eye) and Color Rendering Index (CRI, which assesses visible light color fidelity) are physically meaningless for UV-A sources. UV-A lamps do not produce visible lumens, making lumens per watt (lm/W) an inapplicable efficiency metric. Similarly, CRI >90 is irrelevant as UV-A does not render visible colors. Efficiency for UV-A LEDs is correctly measured in Wall-Plug Efficiency (WPE), expressed as optical radiant power output (watts) per electrical watt input, or more commonly as irradiance (W/m² or mW/cm²) at a specified distance.
For UV-A LED lamps, the relevant technical specifications focus on optical power and spectral characteristics. Beauty STC UV-A lamps typically operate at peak wavelengths of 365 nm, 385 nm, or 395 nm, with spectral bandwidths (FWHM) of 10-15 nm to ensure precise application performance. Radiant flux output ranges from 500 mW to over 10 W per module depending on configuration, with WPE values typically between 15% and 25% for high-end industrial-grade emitters. Irradiance levels are application-specific but can exceed 10,000 mW/cm² at 10 mm for focused curing systems. Thermal management is paramount; Beauty STC employs advanced aluminum-core PCBs and active cooling in high-power fixtures to maintain wavelength stability and extend LED lifespan beyond 20,000 hours at 70% output.
Regarding environmental protection, Beauty STC UV-A lamps are engineered with robust ingress protection. Standard industrial models achieve IP65 rating (dust-tight and protected against low-pressure water jets), suitable for factory environments with particulates or occasional splashes. For harsher conditions such as outdoor use or washdown areas, IP67 (dust-tight and immersion up to 1m) or IP68 variants are available through custom engineering. All enclosures utilize UV-stable polycarbonate or tempered glass lenses with specialized anti-reflective coatings to maximize UV transmission and resist solarization. Sealing employs multi-layer gasketing with silicone O-rings rated for continuous UV exposure.
Beauty STC’s quality commitment is evident in our rigorous manufacturing standards. Every UV-A lamp undergoes 100% spectral validation using calibrated spectroradiometers to ensure wavelength accuracy within ±2 nm and consistent radiant power. We implement MIL-STD-883 thermal cycling tests and 85°C/85% RH accelerated life testing to guarantee reliability in demanding conditions. Our ISO 9001-certified production lines feature automated optical inspection for solder joint integrity and hermetic sealing verification. Unlike commodity UV products, Beauty STC lamps use phosphor-free InGaN die on ceramic submounts to prevent output degradation, backed by a 3-year warranty on critical performance parameters. This focus on precision engineering ensures stable UV output for mission-critical applications where inconsistent irradiance could compromise processes like adhesive curing or forensic analysis.

Application Scenarios
UV-A LED lamps serve specific non-disinfection purposes primarily in entertainment, security, and specialized visual applications within commercial environments. It is critical to distinguish UV-A (315-400 nm) from germicidal UV-C (100-280 nm). UV-A does not effectively kill pathogens and should never be marketed or used as a disinfection tool in these settings. Misapplication poses significant health risks including eye damage and skin irritation with prolonged exposure.
In hotels, UV-A LED lamps find limited but valid use in designated entertainment venues such as nightclubs or themed bars where blacklight effects create visual appeal for fluorescent decor, body paint, or special events. Some high-end spas may incorporate them cautiously in controlled nail curing stations, though dedicated nail lamps are preferable. Reception areas might utilize them strictly for currency or ID validation under shielded counters where staff are trained to minimize exposure. Crucially, UV-A lamps must never be installed in guest rooms, hallways, lobbies, or public relaxation areas due to uncontrolled occupant exposure risks and potential guest complaints regarding unintended fluorescence of personal items.
Within malls, UV-A applications are almost exclusively confined to security and retail functions. Currency validation stations at cashier desks or security checkpoints use shielded UV-A sources to detect security threads in banknotes. Certain retail displays, particularly in novelty stores or children’s sections featuring glow-in-the-dark merchandise, may employ discreetly mounted UV-A lamps to enhance product visibility under controlled conditions where direct viewer exposure is brief and incidental. General mall lighting, food courts, restrooms, or common walkways are entirely inappropriate locations for UV-A installation due to the constant public presence and lack of exposure control.
Offices present the most restricted legitimate uses. UV-A lamps may be installed in specific security or finance department workstations solely for document verification under shielded task lighting, ensuring no direct line of sight to occupants. Laboratories within corporate facilities might use them for material inspection or fluorescence microscopy, but this requires stringent engineering controls. Open-plan offices, meeting rooms, restrooms, cafeterias, or executive suites are absolutely unsuitable environments for UV-A lamps. The risk of chronic low-level exposure to employees during standard work hours is unacceptable and violates occupational safety standards in most jurisdictions.
Installation must prioritize human safety above all else. Never mount UV-A lamps in open fixtures where direct or reflected UV radiation can reach eyes or skin. Always use fully enclosed, interlocked fixtures with physical shielding that blocks UV emission outside the intended target area. Install at heights and angles preventing line-of-sight exposure to occupants, typically above 2.4 meters with downward baffling. Include prominent warning labels indicating UV radiation hazard per IEC 62471 standards. Implement automatic shut-off mechanisms via motion sensors or timers in unattended areas. Crucially, verify local building and occupational safety codes as many regions strictly regulate or prohibit public UV-A exposure. Conduct radiometric testing post-installation to confirm UV levels in occupied zones remain below 3 mW/m² for chronic exposure as per ACGIH guidelines. Staff operating near these installations require specific UV safety training and appropriate protective eyewear rated for UV-A. Remember that UV-A’s primary role here is functional or aesthetic—not health-related—and reckless deployment invites liability and health incidents.
