I use a 150 watt ceramic heat emitter for heat in my 60 gallon. Then i have a 75 watt red heat bulb for nighttime viewing and additional heating. I prefer having a ceramic heat emitter because my tank is in my bedroom and i cant fall asleep with too much light
There are various kinds of tank lights available, but the type you need depends on what tank system you are running. For instance, fish only tanks can use a basic fluorescent light. When choosing a lamp make note of the "spectrum" of the lamp, which is the range of distribution of light. The rule of thumb for lighting is around 0.14W (1 Watt per gal) is a sufficient level to use.
Some of my tanks have just regular zoo med under tank heating pads and others have heating cable. The cable is much better in my opinion because it isn't stuck forever on your tank and in the summer when it is hotter I can reduce the amount of cable I have coiled up under the tank. Even just to have the ability to change where you have the "warm" spot is nice. The under tank pads get destroyed if you tryt o pull them off, they are not meant to be relocated and leave a nasty mes son your tank if you do remove them.
Both the cables and the pads provide more then enough heat (and I have the lowest wattage ones avail) so I would only use a very low wattage nocturnal heat bulb in the winter for a little extra warmth if needed or for viewing. If your enclosure is in your bedroom I'd suggest a blue bulb over the red ones, less bright.
I have a UTH pad and a 60 watt red warm lamp on the warm side. The UTH does not seem to get really warm so I added the light fo a bit more warmth, plus my leo likes to lay on his hamcok under it..
