ultraviolet light flashlight uvb lamp bulb

Product Description

The 295nm 5W UVB LED Lamp is a handheld ultraviolet B LED lamp designed for specific applications, controlled exposure, testing environments, and custom devices. In contrast to the standard screw-in UVB lamp bulb, the current model is developed as a portable UVB LED lamp powered by batteries and featuring protection functions and temperature control.

The product uses the 295nm wavelength and 80mW radiation flux. The 295nm wavelength belongs to the UVB spectrum and is appropriate for the needs of users looking for a portable UVB lamp bulb for their specific testing or research.

The product uses 5W power and a simple 1-mode output. The lamp is convenient to operate due to its easy mode without unnecessary mode switching. The model is good for those 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. Required battery type is 2×26650 rechargeable Li-ion batteries; batteries are not included.

The product features the low voltage protection and anti-reverse connection protection in order to increase reliability. Low voltage protection is 5.6V. In case of inserting a battery in a wrong way, the lamp will not light but the circuit will not burn. Users need to insert the battery correctly.

The temperature control function is aimed to regulate the temperature during operation. The temperature control setting is 55°C. When the temperature is 55°C, the current is reduced to 350mA within 20 seconds. When the lamp is cooled down to 40°C or 45°C, the current increases to 700mA.

The lamp has the dimensions of 222mm in length, 45mm head diameter, and 33mm body diameter. The weight is 290g, and the lamp is convenient for handheld use and has a robust design.

For buyers who are looking for a UVB lamp bulb but need a portable 295nm UVB LED lamp with 5W power, 80mW radiation flux, 2×26650 battery operation, low voltage protection, reverse polarity protection, and temperature control, this model is an appropriate choice.

The use of UVB radiation may affect skin and eyes, so it is important to avoid direct exposure and use adequate protective equipment. The product must not be used for medical purposes unless operated under the supervision of qualified professionals.
