The blue globes etc, that you bue from bunnings, are fine for some things, but you can greatly increase the temperature out put by using something that is designed for heat output. For example, a basking light, or a heat emitter (ceramic).

Then again, species and enclosure dependant, you may want to just go with a compact fluoro and run with heat mats or heat cords.

There are many variations, just depends on what is going to work in your situation.
