> You can get it on line. I've heard that the full spectrum lights on lamps don't really work that great. It's only effective with the amount of light and the distance you are from it (like 18 inches). it's a pretty exact science. So even if the light box is on and you move three feet away, the effectiveness drops dramatically.
Katia is correct. According to the research, it is the intensity (usually expressed in LUX) of the light that is the important factor. It is not necessary for the light to be "full spectrum." All of the medical grade light boxes use a bright white color temperature, so far as I'm aware.
