If you live in a decently warm house. Like you don't have AC running in the room as the cage or in the winter, if you have it, it stays warm in the house, you don't really need lamps. As long as the ambient stays around 80 in the cage your fine. I don't use lamps at all. I haven't in years. The only time that I suggest lamps is a during the winter if people have tanks on a rheostat or dimmer.
