Paint some of the white stuff on it from the inside of a fluorescent tube, and you'll have a complicated white light bulb.
They made us wear safety glasses at my last place, they had a lot of welding bays, and claimed that clear polycarb safety glasses spread out the uv from a flash enough to largely reduce the effects, so a piece of clear polycarb might work. Does the bulb flash like in the vid or is it slower or faster in real life.
