## Questions & Answers

**Q: The light turns red quickly when using indicating it needs charging but when i plug it in, almost immediately turns green? Turns red again  when used?**
A: [Please note]: If the flashlight is not used for a long time, the battery may be in a virtual state, which might cause the flashlight to initiate a red light reminder indicating a lack of power.

[We suggest]: 
1. Unscrew the tail cap of the flashlight (disconnect the battery) then screw back the tail cap back (reconnect the battery to the flashlight). 
2. Charge it again, turn on the flashlight to restore the normal power indicator.

[Important Tips]: When you do not use the flashlight for a long time, please charge the battery every two months to maintain optimum performance.

Dear friend, if you need more help, please contact DARKBEAM's customer service directly. We offer 24-hour prompt response and will serve every customer wholeheartedly.

**Q: How many lumens does this output?**
A: I believe the criteria for these lights is more of the UV spectrum.  Lumens is more for visible white light...but I could be wrong about this.

**Q: Should I wear UV glasses with this and if not, why?**
A: Hello,
Thanks for asking the question.
[Please note]: UV light is ultraviolet light, please do not look directly at UV light.
If you need to use the UV flashlight continuously for a Long Time, we recommend that you wear the UV protective glasses to avoid eye burns from UV light. Your eyes may feel discomfort from prolonged exposure to high intensity UV light.
If you only use it for a short period of time, such as a quick banknote inspection, checking for cat ringworm, etc., it is okay not to wear UV glasses (However, the safest way is to continue wearing UV glasses).
Hope to help you.

**Q: I bought one of these and one of the lights works off one of the led's but the second time i click it the light uses both led's is that normal?**
A: It's normal.
