[alt-photo] Re: UV Point Light Source

[Mike and Jan Andrews]

I once experimented with an arc welding kit to expose a print!  You probably won't want to take this idea too seriously.  It can be hazardous - it gave me a significant sunburn in about 10 minutes!  However it is pretty near to being a spot source and it has significant amounts of UV.
