I'm similar to Dawn D., I just went and got some cheapie Home Depot 4' t-12 fluorescent fixtures (like $8 each, with bulbs: around $15 per double light) and hung them around my shop. I've got my little 8' x 8' workroom (basically, it's the den in my single-wide trailer) set up with benches in a ring around the perimeter (with cheap and/or home-made shelving built in above most of them and all the tools packed in tight on the benches, leaving me room in the middle to basically pivot around and get to any tool I need.) I've got three of those fluorescent light fixtures in there, and along with a single, centered overhead light that was originally in the ceiling (with a compact fluorescent bulb), I've got more light than I need.
Above each bench on each wall, I've got a power strip with 6 plug-ins and I just ran the stock cords that come with the cheap fixtures through a couple of hooks and down the wall into the power strips. The rest of the outlets in the strips have all my other tools plugged into them, so when I walk in the room to get to work, I just hit the 'on' button on each strip, and the room lights up like daylight. When I leave, I just shut the strips off, and I'm good.
My goal is to get this little room totally set up to be as efficient as it can be, and then when I'm happy, I'll buy a 16' x 8' cargo trailer, and I should have roughly twice the space I need to duplicate my current shop, leaving me the other half for cargo space. That way, when I start hitting the shows, I'll be able to work while I sell off my treasures, providing I can get a 15 amp power source. That's one of the things that's been keeping me so busy, trying to cram so much stuff in such a little space. I think I've about got it, though. Now I just need to upgrade to some better tools (i.e. swap out the 9" hokey bench bandsaw for a real 14" Grizzly, get rid of my 12" miter saw for a good 10", things like that)
Hope some of this helps. The nice thing about our little addiction is that it really doesn't take up that much room to set up a good shop.
