To determine the lighting requirments for my new shop, I did my homework by searching the threads in this forum, reading the magazine articles, and downloading Lithonia's Visual software. I ended up with 9 4-bulb T-8s in my 20' by 28' shop space (upstairs over a new garage). I haven't got my tools out of storage yet - but I think I'm going to be happy.
One thing I didn't consider - the glow coming from my shop! The day after the power was turned on, my neighbor came over and asked if I was going to put blinds on the windows. I thought that was funny until I heard her talking to my wife about the same topic 2 days later. I've got tarps over the windows on that side until I can get some blinds installed. You just can't think of everything!
