flashlight with uvb light

Product Description

The 310nm 5W UVB Light is a handheld ultraviolet B light developed for inspection, UVB exposure use, fluorescence test, and related research purpose. It features 310nm wavelength with 90mW radiation flux, offering a special-purpose UVB lamp for people seeking a dedicated UVB portable lamp.

It is equipped with 5W power design and 1-mode function. The one-mode setting makes it possible to operate directly, without adjusting the brightness. Thus, it is ideal for those who want easy on/off operation in inspection, testing, and special application environment.

It runs with an input voltage from 6V to 12.6V, and needs 2×26650 rechargeable Li-ion batteries. One battery cannot launch this product. Batteries are not provided with the purchase, so you need to prepare two batteries beforehand.

For safe and reliable performance, this UVB light is provided with low voltage protection and anti-reverse connection protection. Low voltage protection is set at 5.6V. In case if you reverse your battery, this lamp will not start but will not burn out. You just need to install the battery properly.

Another important feature of this UVB light is temperature control. Temperature control is set at 55°C. At 55°C temperature, the current decreases to 350mA within 20 seconds. Once the lamp is cooled to 40°C or 45°C, the current increases to 700mA.

This UVB light has a 222mm length, head diameter 45mm and body diameter 33mm. The weight is 290g, offering handy dimensions and solid construction for special UVB application.

Since UVB radiation can damage the skin and the eyes, it is necessary to comply with all safety rules, avoid direct exposure to the radiation and use all required equipment while working with this UVB light. For medical purposes, usage should be made according to professional instructions.
