Night time UVB/amount

it is not about placement it is about reliable thermostat, a heat pad that is uncontrolled will reach temperatures that will be too high and
can cause serious issues, from burn to fire hazard.

Again you need a thermostat to maintain and control the heat.

Case in point(for everyone):

In my younger days when attempting to use a UTH without heat control and leaving it "open air", I came home to find my UTH hanging from the tank with a melted hole in the middle of it and sparking. After using the UTH for less than 60 days. Thankfully I had it set up the way I did so it didn't burn the animal nor actually come in contact with anything flammable.

For a time I thought UTHs were the devil until I finally did some research(thank you BP.net) about them and using a thermostat.
