I have a friend who setup lighting in there garage where he works on servers, he was really proud of his new lights, when I came in, I was shocked to see he picked the worst lights possible, blinding blue/white, flickering, shining directly into your face.

I don't know how he does it, but I can't stand it.

Also, at work we have fluorescent tubes, it's so bad. Sometimes when I work weekends (by my self), I'll leave them off when I get in, just use natural light. It's so much nicer. Also helps that the building "A/C" is off too. I quote it because it's a sad excuse for A/C which barely cools, just makes a huge amount of noise for doing nothing.
