If you see a light bulb above my head, it doesn't necessarily mean that I've got a bright idea. It probably means that I went to businesslights.com to purchase all of my light bulbs. They specialize in energy and maintenance efficient lighting. In my office, I only use a Metal Halide light bulb to keep the room a little cooler, because I find that the standard light fixtures tend to heat the room up a few degrees. There's nothing in the world as bad as programming when you are dripping with sweat.
