I use envirolites and get good results using 200w for both veg and flower (last grow was 4oz dry in 2.5x1.5' - would've been more if I could resist picking the buds before they finished).

They are great CFLs cos they are designed for growing, and therefore most of the light output is in the spectrum used for plant growth. You can also make an effective reflector from the box they come in

Household CFL are not designed for growing - though you obviously can get cool and warm CFLs, my guess is they are not as effecient in terms of light spectrum as a specialist grow light.
