Battery charging:
First-time usage (for flashlights shipped with battery):
Unscrew the back off the flashlight and remove the
protection spacer from the battery and fully charge the
battery before first usage! The battery is in storage mode
and needs to be charged as soon as possible!
The C255-4 must be used with one rechargeable 26650
Lithium-Ion battery (>5000mAh, minimum 10A discharge
type) or one 18650 Lithium-ion battery (>3400mAh,
minimum 10A discharge type) with the included spacers.
When the battery is almost empty, the flashlight will start
to flash and eventually will shut down the lamp. When
flashing starts, recharge the battery as soon as possible!
Warning:
1. Place the battery with the + to the inside. Reverse
placement can destroy the flashlight and battery.
2. NEVER look directly into the light beam. This can
damage your sight! Wear safety glasses! UVC radiation
is invisible! UVC radiation can be harmful!
3. This lamp is NOT suitable for children, it is NOT a toy.
4. Don’t aim the light beam directly to your skin. Exposure
can damage the skin tissue! UVC radiation can be
harmful!
5. Never point the light beam to any other living person or
animal! UVC radiation can be harmful!
6. Do not operate the lamp for more than 5 mins
continuous. Use it with intervals to cool it down. Keeping
the led cool prolongs its life.
7. Do not disassemble the flashlight or make any
modifications. This will void the warranty.

* Current research has shown that 255nm leds don’t seem to cause solarization. Solarization might only be caused by
ozone which is generated by uvc wavelength between 100nm and 240nm. 254nm Hg tubes also emit sidebands in
these deeper uv ranges, 255leds in contrast have a very narrow bandwidth and don’t seem to form ozone. This would
mean a much longer lifespan of the filters than the estimated 1000hrs. More scientific research is being performed on
this. Any new info will be updated
