+ one on that! It says can be recharged by exposing to light. So unless you go from light to dark in a instant I don't think it'll work. It's pretty much the same thing on watch hands! And my watch needs a lot of light to charge it.mike_honcho87 said:I can see this working if you go from light to dark, but if you're woke up in the middle of the night you'll have to put it under light to charge the paint back up.
