flashlight with uvb light

Product Description

The 310nm 5W UVB Light is a handheld ultraviolet B light designed for specialized inspection, controlled UVB exposure applications, fluorescence testing, and research-related use. With a 310nm wavelength and 90mW radiation flux, this product provides a focused UVB output for users who require a compact and portable UVB light source.

This model is built with a 5W power design and 1-mode operation. The single-mode structure allows direct use without multiple brightness settings, making it suitable for users who prefer simple on/off operation in testing, inspection, and controlled application environments.

The UVB light operates with an input voltage of 6V-12.6V and requires 2×26650 rechargeable Li-ion batteries. One battery cannot start the product. Batteries are not included, so users should prepare compatible 26650 Li-ion batteries before operation.

For safety and reliability, the product includes low voltage protection and anti-reverse connection protection. The low voltage point is set to 5.6V. If the battery is installed in the wrong direction, the light will not turn on, but the circuit will not burn out. Users only need to reinstall the battery correctly.

Temperature control is another important feature of this UVB light. The temperature control point is set at 55°C. When the temperature reaches 55°C, the current is reduced to 350mA within 20 seconds. After the product cools to 40°C or 45°C, the current rises back to 700mA. This design helps support more stable operation during use.

The product measures 222mm in length, with a 45mm head diameter and 33mm body diameter. The weight is 290g, making it suitable for handheld use while still providing a solid structure for specialized UVB applications.

Because UVB radiation can affect skin and eyes, users should follow proper safety procedures, avoid direct exposure, and use protective equipment when operating this UVB light. For medical or therapeutic use, operation should only follow qualified professional guidance and applicable regulations.
