Most days, I work with a computer screen all day for my job. If I get to do any painting, it's at the end of the day when my eyes are already tired...and my eyes aren't great to begin with. I recently purchased some lamps made by OttLite since I'd heard good things and they were running a buy-one-get-one deal.
They've helped with painting, and I think they also keep colors more true to life when taking pictures. Below are some comparison pics of the same model. Granted, the model received a little work between photo sessions, but the work was minimal: rust, patina, lips, and matte varnish. In most areas of the model, however, the only difference is the matte and the lighting. I thought the difference was interesting.

I'm happy with the little lamps I have, so much that I might shell out for one of the larger floor lamps in the future. If I ever get around to making a light box, I think these lamps would help there too.
