>>2827848Charging batteries is a pain and can be dangrous; just buy a few spare AA/AAA batteries — they're everywhere. My Kodak camera and MP3 player run on them too. I like how universal they are. Sadly, they didn't invent phones with these batteries.
Pic related lights (except the one in the middle) have good-quality warm-white LEDs and are dimmable. You can get 180–250 hours of light with new batteries.
