Sounds like you're off to a pretty good start, just give him time to settle in and try to be patient and gentle in your handling. Also persistent! Try to handle him 2 or 3 times a day, but just for 10 or 15 minutes so he doesn't get too stressed out.
Oh, and what brand of light do you have? If it's a mercury vapor it's fine, but a lot of bulbs are sold as having "full spectrum" or "natural" light that don't give off UVB.
