Does the led used for the flash/flashlight emit UV? Also does anyone know the wavelength of the led?

Just wondering if it emits any harmful UV light. I have a bottle of Blue Lizard that has a UV smart bottle that turns blue in UV light. I shined the led on the bottle and it turned blue where the led beam was pointed. I was wondering if it was from UV being emitted or heat from the led.

This brings to mind a sign I once saw on the door to a physics lab: "Do Not Stare Into LASER With Remaining Eye". The point here being, unless you do something stupid like stare into the light or are working with extremely delicate artifacts, you are in no danger.

No, & you can't get tanned shinning it on yourself.
