Strong CFL's in a small area, could that match an HPS system?

Is it really accurate to compare my cfl grow with a 400w HPS system? I mean, no one would actually recommend a 400 W HPS system in a 3 cubic foot, 1 square foot grow chamber.

Use a small hps, my 3x3 space will have a 250w hps once I get set up again, I think they make 100w hps too, but I'm not sure. as long as the temp is good, you can pack a tiny room with big lights!
