ultraviolet light flashlight uvb lamp bulb

Product Description

The 295nm 5W UVB LED Lamp is a handheld ultraviolet B light source designed for specialized UVB applications, controlled exposure work, testing environments, and custom device integration. Unlike a standard screw-in UVB lamp bulb, this product is built as a portable battery-powered UVB LED lamp with protection functions and temperature control.

This UVB lamp bulb alternative uses a 295nm wavelength and provides 80mW radiation flux. The 295nm wavelength is within the UVB range and is suitable for users who require a compact UVB light source for specific testing or research-related applications.

The product uses a 5W power design and a simple 1-mode output. This makes the lamp easy to operate without unnecessary mode switching. It is suitable for users who need direct UVB output from a compact handheld device.

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

To improve reliability, this UVB LED lamp includes low voltage protection and anti-reverse connection protection. Low voltage protection is set to 5.6V. If the battery is inserted in the wrong direction, the lamp will not light up, but the circuit will not burn. Users only need to reinstall the battery correctly.

The temperature control function is designed to help manage heat during operation. The temperature control setting is 55°C. When the temperature reaches 55°C, the current is reduced to 350mA within 20 seconds. After the lamp cools to 40°C or 45°C, the current rises back to 700mA.

The lamp 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 buyers searching for a UVB lamp bulb but needing a portable 295nm UVB LED light source, this model provides a practical solution with 5W power, 80mW radiation flux, 2×26650 battery operation, low voltage protection, reverse polarity protection, and temperature control.

Because UVB radiation can affect skin and eyes, users should avoid direct exposure and use proper protective equipment. This product should not be used for medical treatment unless operated under qualified professional guidance and applicable safety regulations.
