OP, I would recommend something with a probe to regulate temps. Rehostat or thermostat. Flex is absolutely NOT recommended to be used without a professional quality thermostat but people here still use dimmers. If you have a large amount of substrate, you may want to take some of it out. The flex is going to need to heat through a lot of that and the temps at the glass can get very hot and even burn your snake.

Get a digital thermometer, Accurite is recommended, and use that to measure your temps to make sure nothing is to warm for your animal.
I'll be pickin up a accurite soon, I'm switchin to flexwatt b/c my lights are killin the humidty.. the acurite I was lookin at has a probe to it already..
