overhead lamp/lighting

[51-50 Python]

what type of overhead lamp/bulb should i get for a ball python?

also, is it absolutely neccesary to get a humidity measuring thermometer?

like i said in ur other thread.. i have a black light bulb and its worked just fine for me... and about the humidity measuring.. i guess its better to have one just to make sure but i dont use one and my snake has perfect sheds.. meaning it has the right humidity
