Actually it's not a ceramic heater, it's a ceramic heat emitter. It doesn't go in the tank so less chance of burning the frog. It looks like a lightbulb and screws into a heat lamp. It works like a heat light too, but doesn't burn out so quickly. Edit: I'd suggest getting a heat lamp and suspending it, that way you can keep it on a timer if you want. Ideally it should have a dimmer, but I've had trouble finding lamps with dimmers rated over 75watts. I've been raising and lowering the lamp on its stand to control the heat.
