Technical Specs & Certifications
When discussing “UV from LED,” it’s important to clarify that ultraviolet (UV) light falls outside the visible spectrum and is typically measured in radiant flux (watts) or milliwatts per square centimeter rather than lumens, which quantify visible light as perceived by the human eye. As such, lumens per watt (lm/W) — a standard efficacy metric for visible-light LEDs — is not applicable to UV LEDs because they do not produce visible lumens. Instead, UV LED efficiency is evaluated using wall-plug efficiency (WPE), which is the ratio of optical UV output power to electrical input power, expressed as a percentage.
For applications requiring high-quality visible white light with strong ultraviolet components — such as in UV curing, counterfeit detection, or special effects lighting — some LEDs are designed with violet or near-UV pump chips (typically 395–410 nm) combined with phosphor coatings to produce visible white light. In such hybrid systems, traditional photometric metrics like lumens per watt and Color Rendering Index (CRI) become relevant.
Beauty (STC) Manufacturing Co., Ltd. specializes in high-performance LED lighting solutions, including fixtures engineered with precision UV or near-UV components for specialized applications. While our standard visible-light LED products are not classified as “UV LEDs,” we offer advanced phosphor-converted white LEDs driven by near-UV or violet pump technology, capable of delivering exceptional color fidelity.
For these high-CRI visible lighting products, Beauty STC achieves:

Application Scenarios
UV light from LED sources, particularly UVC LEDs, is increasingly being used for disinfection and sanitation purposes in various commercial and public environments. When properly applied, UV LEDs can help reduce the spread of pathogens on surfaces and in the air. However, it is crucial to understand where and how to use them safely and effectively.
In hotels, UV from LED can be deployed in guest rooms, especially for disinfecting high-touch surfaces such as light switches, remote controls, door handles, and bathroom fixtures. UV LED systems can also be integrated into HVAC units or air purifiers to sanitize air circulated throughout guest areas. Additionally, some luxury hotels are incorporating UV-C LED solutions in minibars, safes, and even luggage sanitizing stations. For installation in guest rooms, ensure that UV LEDs are either operated remotely or when the room is unoccupied, as direct exposure to UVC light can be harmful to skin and eyes.
In malls, UV LED technology is best suited for use in air handling systems, restrooms, escalator handrails, and fitting rooms. Continuous or periodic disinfection of moving handrails using UVC LEDs has become a common application, as these surfaces are constantly touched by visitors. Installation should be enclosed or shielded to prevent public exposure. For fitting rooms and restrooms, automated UV systems can be triggered after each use to sanitize surfaces. Proper timing and motion sensors are essential to ensure safety and effectiveness.
In offices, UV LEDs can be used in shared workspaces, meeting rooms, and ventilation systems. Desks, conference tables, keyboards, and shared equipment can be disinfected using portable or fixed UV LED units during off-hours.
