Reverse Polarity Protection Over-Discharge Protection Low Voltage Warning Fully regulated output, no PWM, no circuit noise Black filter glass lens, effectively filtrate the visible light beyond 365nm for purer UV beam. Purple oxidized aluminum alloy protection bezel Anti-slip, anti-roll design 1 meter impact resistance O-ring sealed, IP67 water resistance rating Individually serialized Dimensions: (Bezel Dia.) 27.5mm x (Body Dia.) 23mm x (Length)135mm Weight: 80.5 grams (w/o battery) Accessories (included): O-ring
Open the tail cap by twisting counter-clockwise, insert a charged quality 18650 lithium battery with the positive terminal towards the bezel, and tighten the tail cap by turning clockwise.
The flashlight has Reverse Polarity Protection, the light will not be damaged by batteries inserted in the wrong orientation, but it will not turn on. If this occurs, please check the battery orientation.
Fully press the tail switch until "click" is heard to turn on the flashlight. Each time the flashlight is turned on, the default setting is "LOW".
When the flashlight is on, half press the tail switch to cycle between LOW and HIGH output. Fully press the tail switch until "click" is heard to turn off the flashlight.
When the battery voltage is too low, the flashlight will flash 2 time as a warning. When the flash is given, please change to a new battery.
After the first flash warning, the flashlight will operate for several minutes as a safety measure.
After several minutes, the second flash warning will be given. After this warning, the flashlight will shut off automatically.
