uvb 311 nm lamp led tube 9W replace philips 9W uv bulb
Product Details Description
The yoyouv DS-UVB311-3535-15W is a 311nm UVB LED lamp designed for phototherapy LED equipment. It uses a high power UV LED light source with 15W power, 85-265V voltage input, 90mA current, 4-7mW radiant power, 120° view angle, IP20 waterproof rating, and a 3-year warranty.
This uvb 311 nm lamp is developed for equipment used in vitiligo, psoriasis, and atopic dermatitis phototherapy applications. It should be positioned as a UVB LED light source for controlled phototherapy device development, not as a general lighting bulb, tanning lamp, blacklight bulb, mosquito lamp, or UVC sterilization lamp.
The product wavelength is 311nm. This matches the common narrowband UVB search demand for 311nm UVB phototherapy lamps. For accurate product communication, the specification should clearly show 311nm and should not be mixed with UVA wavelengths such as 365nm or 395nm.
This UVB LED bulb could replace Philips 9W UV bulb applications in suitable equipment designs. However, replacement should not be described as universal without validation. Engineers should confirm fixture size, mounting method, electrical input, irradiance output, exposure distance, beam distribution, timer control, and safety protection before using it as a replacement light source.
The standard size is 24 x 4 x 3cm, and customized size options are available. This gives OEM customers flexibility for handheld phototherapy devices, localized UVB exposure modules, replacement lamp assemblies, compact equipment housings, and custom LED phototherapy products.
The 120° view angle provides a broad UVB output pattern for local exposure areas. In a final phototherapy device, the actual exposure field depends on LED arrangement, housing design, working distance, optical window, reflector structure, and protective shield. Irradiance uniformity should be tested in the completed product.
With 4-7mW radiant power, this uvb 311 nm lamp is suitable for compact phototherapy light-source integration. The final therapeutic effect depends on the complete device, exposure time, distance, dose control, treatment area, skin condition, and professional operating instructions.
The high power UV LED series is designed for high current operation and high power output applications. The SMD design and low thermal resistance material help support compact assembly and better heat transfer when the lamp is installed into a properly designed thermal structure.
The IP20 rating means this lamp is not waterproof for open wet environments. It should not be exposed directly to water, rain, high humidity, or wet treatment areas unless the final equipment provides additional protection. A finished device should include enclosure design, driver circuit, heat dissipation, timer control, shielding, warning labels, and user instructions.
This product is a UVB phototherapy LED light source. It is not a consumer self-treatment recommendation. UVB phototherapy should be used under medical or professional guidance, with controlled exposure time, dose, distance, treatment schedule, and eye protection.
Do not look directly at the operating UVB lamp. Avoid unnecessary eye and skin exposure during testing, assembly, installation, and operation. Use UV protective eyewear, shielding, timer control, interlock design, warning labels, and safe working procedures in the final equipment.
