flashlight uv light led torch lamp 255nm

Product Description

The 255nm UVC Flashlight UV Light is a handheld ultraviolet-C light source designed for controlled germicidal applications, surface exposure work, laboratory environments, and professional UV testing. With 5W power, 255nm wavelength, and 30mW radiation flux, it provides a compact UVC source for users who require portable short-wave ultraviolet output.

This flashlight UV light is intended for controlled use on surfaces, tools, devices, and small target areas where UVC exposure is required. It may support disinfection workflows in medical environments, laboratories, maintenance areas, and water purification system testing when used according to proper operating procedures.

The input voltage is 6V-12.6V. Please use 2×3.7V Li-ion batteries. One battery cannot start the unit. The required battery type is 2×26650 rechargeable Li-ion batteries, and batteries are not included.

To improve reliability, this flashlight UV light includes low voltage protection and anti-reverse connection protection. Low voltage protection 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. Users only need to reinstall the battery correctly.

The temperature control function helps manage heat during operation. 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.

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 maintaining a solid structure for professional UVC applications.

Because 255nm UVC radiation can be harmful to eyes and skin, this flashlight UV light should only be used by trained users with proper protective equipment. Do not point the beam at people, animals, eyes, or skin. Use it only in controlled areas, and follow all applicable safety instructions and local regulations.

For buyers looking for a 255nm flashlight UV light with 5W power, 30mW radiation flux, 2×26650 battery operation, low voltage protection, reverse polarity protection, and temperature-controlled output, this model provides a practical UVC source for controlled professional applications.
