Lightbulb watts vs Heat emitted
So I know this is a odd question but I cannot find anything on it online, I have 11 hermit crabs in a tank and the temps have to stay pretty high for them to be happy.
I have been using a small light bulb that is 40w 120v to keep it warm in the tank, well with the cold weather its been getting to not be hot enough and I already have a heating pad on the tank too
So I was wondering if a 60 watt bulb or a 100 watt bulb would increase the temperature in there or is it dependent on the volts?
