I'd guess that the fluorescents put out less heat, and more light.

Your guess would be wrong. *Think about it.

For a given input power, say 25 watts, the compact fluorescent puts
out more light energy than the 25 watt incandescent light bulb.
Unless there is a new law of thermodynamics, if the compact
fluorescent light puts out more light energy, it must put out less
heat energy. Now, we can argue the amount of the difference, but
there is a difference in the heat output between two 25 watt devices.
