For my Jackson's I use a 100 watt uva/uvb/basking bulb in one. They both blew and I want something asap. I found one store that has a 125 watt bulb. will that get too hot for a jackson??
possibly
you can raise the bulb up further from the basking area until the temperature is correct for the animal (I assume you are measuring this). But because its an all in one bulb you may find that doing this also reduces the effective UVB area.
