UV torch for charging lume

I would like to pick up a small UV light (ideally on a keychain!) for powering up lume. My 5 minutes of searching on Amazon turned up lots of options for bulbs, wavelengths, and whatnot. Is there a particular set of specs that’s best for watch purposes?

Thanks!

Any torch / flashlight with 500+ lumens will charge a watch. Don’t worry about the spots. They will disappear after several minute.

RovyVon has some nice little keychain lights with built-in UV light. The UV light isn't all that strong on the keychain models, but it still does a good job of charging lume.

Thanks! It sounds like I should set my sights for something larger than keychain size.

Don’t look directly at the sun? Gotcha! 😉
