I'm figuring the light is a UVB light which isn't required for snakes. You will need a lamp of some sort---a red light or blue light so you can leave it on all the time---or an undertank heater. You need to give the snake a temperature range... one end of the tank needs to be warmer and the other end needs to be cooler so he can regulate his temperature. This will require another hide... one for the cool side, one for the hotter side.

Read the care sheet... you're going to have to get a guage---Accurite is good, from Walmart---to measure the temps and humidity.

Have fun
