CFL flood lights?

Could CFL flood lights be used to grow?

From everything I have read they should work for flowering (2700K) but I have read people say they used warm/soft for VEG too and although slower it will work. I think it would be less expensive to just get some regular 26W spiral CFLs Hope that helps.
