Hari,

VERY fancy exposure box.

Being a minimalist, I bought two of these

e/16879944

for about $12 each including tax. I bolted a thin bar across the top of each
side to yoke the two fixtures together. Then I put the assembly on 2.5" tall
spacers. Works fine for me. I expose my pre-coated boards for 8 minutes,
develop in under 20 seconds, and etch in warm ferric chloride in under 10
minutes.
