Review: Darkbeam 365nm+395nm UV flashlight (+COB white and red) $18

How about battery life?

[@summetj]

A single (365nm) UV light had a runtime of 3 hours before starting to dim. It took around 5 watt hours to re-charge the flashlight (~1,000 mAh at 5 volts), so the battery capacity is probably in the 4 - 4.5 watt hour range.

Does it create ozone? Kill bacteria

[@summetj]

It is 365 and 395 nm, not 160-240 nm, so it should not create (much) ozone and probably doesn't kill (much) bacteria. [On the plus side, it is more "eye-safe" than true shortwave UV.]
