Haven't you provided a hide on the cooler side of the tank?
Raise the light above the tank but not too far. Cut a hole in a tupperware and give Snakey a cool hide and get a thermostat asap.

I use a 75 watt infrared light to assist in heating my decorative glass BP enclosure. The temps are fabulous and consistant but it took a lot of fiddling and some cash to get it right. A thermostat is a must.
