That;s a good question. I imagine there would be a lot of Rayleigh scattering of UV wavelengths underwater so I don't know how much throw you could get from one.

Oh! That's not good! I don't mess around with UV lights. I think I have three out of my massive collection of hundreds (thousands?) of lights over the decades. Just recently bought a pair of Amber UV-safety lens in case I ever actually need to use one of those three lights.
