ok, so maybe im missing something, im no scientist and im not trying to sell you one light over another....but during all this submersible light talk about what light colors penetrate farther under water, etc, I had an epiphany...correct me if im wrong, but doesn't white light have ALL the colors in it, since none are filtered out? and by putting a color filter on the bulb, aren't you actually limiting its output by blocking all but one wavelength? seems to me, let the water filter the light...and let the fish decide how far from the source the wavelenght/color is too their liking.
