Damn, I just retrofitted my house's lights to 100% compact fluorescent. To dial up to 400W I would need to turn on over 25 lights!
By the way, everyone should do this. We had a light fixture (8 lamp hanging fixture) that was burning 800 watts After I was done with it its been burning at 120 watts (and its still too bright). Along with weather stripping and sealing our crappy windows with insulating film, this is going to be the most energy efficient christmas ever! Hooray!
