You can just do a net energy equation on that one for cold places and say CFL bulbs suck.

Exactly. Most ight bulbs are around the ceiling. Do you spend most of your time on the ceiling? No? That's why we don't count that heat. No matter how much heat ithe bulbs are providing, it's still all waste heat, because they only heat where we can't use the heat anyway. Also, it's "uncontrolled" heat as well.
There's a reason why heat registers are installed in the floor whenever possible.
