For ventilation, past threads have talked about it's best to have fans supplying fresh air (clean shop air?) and the paint air exiting through external filters but without fans. Would the air supply fans be best if they were mounted on the ceiling providing a down draft or in a side wall blowing across? To exhaust air, I'd probably crack the door the width of a filter, build a 2x4 frame and run filters all the way up.
For lighting I was wondering if 4 of those cheapie $10 4' fluorescent light fixtures you can get from Lowes on the ceiling are sufficient, or if I should have lights on the side walls too?
Also concerned about how I should run power to minimize explosion hazards.
