Interesting, actually my Flash LED lost any sort of "lamp" outside, you can see the circuits (i know, it's dangerous for water), do you think it's the same?
Hmm... I am by no means an expert on this, but I'd think the amount of UV light produced
would be small enough to safely use it.
I'm not sure if the phosphors are completely gone, if the lamp is gone, since that's the important part in converting the UV light.
The picture here here shows the phosphor covering the LED. Again, this is just me guessing.
