The M4-365 is a high-power UV flashlight with a wavelength of 365nm. The UV radiation flux can reach 14,000mW at high power output, and there is a low power mode that can be switched. It uses a 21700 rechargeable lithium-ion battery and a press switch at the tail. The light head adopts a patented through-hole cooling structure and has a black filter lens to filter out stray light of non-365nm wavelengths, and less visible light.The flashlight is equipped with springs to prevent shock, and has reverse battery protection, low battery reminder, over-discharge protection, and temperature protection. The flashlight also comes with a stainless steel pocket clip, making it easy to carry.

This M4-365 "Blue-faced Beast" is a professional UV flashlight with a large irradiation area, high radiation flux and spectral radiation intensity. It is especially suitable for UV curing, non-destructive testing (NDT), fluorescent leak detection, mineral exploration, criminal investigation and evidence collection, and document anti-counterfeiting inspection.

Operation instructions:

First, install the battery correctly, with the cathode of the battery facing the direction of the light head. This flashlight has reverse connection protection. Even if it is installed incorrectly, the flashlight will not be damaged, but it will not work. Please check the battery in time.

After installing the battery, half-press the tail switch button once and do not release it to turn on the high power mode. Release it to turn it off. At this time, half-press the switch again and do not release it to switch to low power mode. Repeat this operation, and the flashlight will cycle between high and low power. When any power is turned on, press the switch hard and the "click" sound will keep this mode running continuously. Press the switch again to turn off the flashlight.

During use, when the battery power is low, the flashlight light will flash as a reminder. Please charge the battery in time.

Tips:

Do not disassemble the parts by yourself, otherwise the warranty will be invalid and the flashlight may be damaged

It is normal to generate heat during high-power use. When the hand feels hot, please switch to low power in time to avoid being burned

High-power output will consume power quickly and accelerate the temperature rise. This flashlight has been set to automatically reduce the output protection function after 3 minutes

After long-term use, the waterproof ring of the flashlight may age. Please replace it in time to maintain the waterproof performance of the flashlight

After long-term use, the grease of the thread at the tail of the flashlight will decrease. Please use professional grease to lubricate the thread in time

Please clean the conductive contact surface of the flashlight in time to ensure the normal operation of the flashlight. You can try to clean it with an alcohol cotton swab

When not in use for a long time, please remove the battery and store it, and charge the battery at least once every 3 months

This flashlight cannot be used as a diving flashlight

When carrying it with you, turn off the flashlight and loosen the tail cover 1/4 turn to avoid accidentally touching the switch and causing the flashlight to turn on accidentally
