i'm using 75 and 100 watt compact flourescents, 8 total, about 6" from the glass. not ideal, but can burn a good screen in 3.5-5 mins, even doing halftones with all those bulbs undercutting the art!

compact flourescents are the long white tubes right? so do you place the lights alternately or all 75Watts on one place and all 100Watts are on the other place?
shirt, they are the swirly tube kind that screw into a light socket. when i built it, home depot only had up tp 75 watts, i had to add a couple bulbs to the middle because it wasn't bright enough in the middle, by then they had 100 watts. they have to be the daylight kind. they are BRIGHT!

oh i get it... so there are only 2 100 watt bulbs there? and they're at the middle of the box?
i love it! i've never had a real "exposure unit" with a vacuum or anything. mine's what i call a jack-uum table, i have a scissor jack that pushes a piece of wood mounted to a beam on the ceiling. i use a thick chunk of foam and a piece of wood for the jack to push on. it works pretty good

about how much did that cost you to make? i am curious because i need a better, more consistent way to burn my screens on a budget. any help would be appreciated.
i never really kept up with an exact dollar amount but, here's a guess
bulbs approx. $7 ea x 8= $56
sockets 1.29 or so, about $12
tempered glass $55
the base was a light table, not really meant for exposing screens, a friend with a print shop (business cards, etc.) gave it to me. i gutted the fluor. tubes and the ballasts, kept the wire for the new bulbs and had to cut out the floor of it and put in a plywood one so the light was far enough from the glass. so all that was free, stuff just laying around. i bought a little digital timer for $4 at target and used a toggle switch i had. it'd be coo to have a timer that would shut it off when the time runs out.
you could build a frame from wood, my first table was. really it wasn't hard or that expensive considering "real" ones are like $1500+! i'll get one eventually, but for now i'll use my diy one
are compact flourescents more efficient than floodlamps of "firefly"?
i have a 150W but until now im having a hard time with it.
i dont have a box, i just clamp it on a cabinet so that it will look down on the screen (12in distance). that's it, not bound in a box. is there any problem with my set-up?
what bulb i use in exposing screen.
