I use red bulbs for my albinos...mostly...it really depends on the garter. Possum, my snow, seems to like a bit of light. I keep a small lamp with a regular 40 watt bulb on a desk next to his enclosure and let him have the light from that for a little bit of time each day. Hermes, my checkered albino, does not like light so much...but he has plenty of hides to go into when the light is on for Possum...and he will occasionally come out when the light is on. Little Joe, my albino red-sided...seems to like light. He has a regular 40 watt bulb in a dome lamp. He doesn't seem bothered by it at all...when he wants to get away from the light, he just moves to the cool side of his enclosure. Just make sure you don't use UV bulbs...as they are dangerous for albinos.
