DIY Exposure Unit: What light source?

[Nicholas Wilson]

hey!

my parents are in town and my stepdad and i are going home depot shopping and are going to build an expsosure unit for my studio today.

gulp.

uv uv uv 48" 48" 48"

this is what i have learned.

are you guys feeling strongly that individual housings/ballasts are smarter instead of the 2 bulb-housings?

Should be the same either way. The ballasts are going to be made to run 1 or two bulbs, so there wouldn't be a downgrade in power. Only issue with a 2 bulb ballast is when one goes out, they both go out.

jinkies....yeah, that makes sense. thanks buster.

that, plus a two-bulb housing wont allow you to vary the distance between the two bulbs...which is important when building the unit. distance between bulbs = distance between bulbs and glass, from what i've always heard.
