Sandy (and others)
Please remind me the optimim UV frequencies for pt/pd printing -- and for carbon if they are different.
I was looking at some interesting bulbs and wondering how practical they would be. Eye Lighting makes a 450W Merc Vapor self-ballasting reflector lamp (#68633) -- screw-in type base (mongol). It has a peak at a wave length of 400, a peak at blue...and then peaks at yellow, orange and red, which would just be a source of heat as far as alt. processes go.
For my carbons I am using two 175W merc vapor lamps -- I'd like to simplify my system by using one lamp and up the wattage.
Edited to add....looked up Sandy's article on the unblinkingeye site. Looks like I need wavelengths of 320 to 400 and that the bulb above would work...if it will give even illumination for a 8x10 at a reasonable height.
The bulb is about $70 -- I'll have to give it some thought. Has anyone used such a bulb?
