Hi Ken,

By any chance do you have a link or a picture of your light fixtures?
I've always wondered why my print times have been so long with the
unit I made and I have to think it might have something to do with the
fact that my Home Depot fixtures leave too much air between my bulbs.
I'm curious about yours.  I'll wait for a better response, because I
am certainly not an expert, but I would suppose that the best approach
would be to cram everything as close as possible.
