Yes it is a heat lamp. I was thinking about a heating pad but I've heard before about the glass cracking which is why I was extremely iffy about it. Will it still work if stuck on the back of the tank and not at the bottom?

I would prefer ​to stick with a heat lamp but am unsure about what wattage of bulb I need.
