Kevin, RL, Vern: Thanks guys.
Bronson, no door yet. Its next on the list. I know what I want to build, but just not sure exactly how to carry it out. We have a couple of good guard dogs, a motion sensor light, nosy family that live close by and next door neighbors that are always home. Plus we live on a large plot of land. But no doors still stress me out. I wouldn't have gone more than a day without doors if I still lived in So Cal though! I got ripped off four times in four years down there. Ugh. Thieves/tweakers... lowest life forms on the face of the planet.
Dan, almost painted these suckers green for that same reason! But, stainless is cool too. I also thought about painting the inside white for better reflection, but they are plenty bright as-is. One could also polish the inside just a little for more light too.
I'm betting that two or three rows would be enough for the whole shop. Mine are spaced 36 inches apart and I guess they could even be 48 apart, but I wanted mine sort of "centered" over the length of the bench. They also hang at about 7 ft off the ground, so any higher might be better for distributing light over a large area, but I'm not sure.
I have the same cheapo ten-year-old Home Depot 4 footers out there that you probably have. The only reason they went up was because I already had them. I'll take some pics for you to see.
Bigger bowls might be even better, but these were the biggest available at Ikea. Maybe I'll see if I can find a few bigger ones to run down the middle of the garage? It'll be cheaper than buying electronic ballasts/new T8 tubes and all that...which is pretty much why I did this in the first place. Newer cheap fixtures without tubes are about $18-20 ea. I think I have about $60 into the lights altogether. I did already have the aluminum cable laying around though.
