When you calculate CFL or Flouro wattage you use the actual wattage of the bulb. on the packaging they usually say "like 125w" this is the incandescent wattage. when you compare the usable lumen's, the wattage will come out to whatever the bulb is rated for. I hope this makes sense? i shouldn't talk when I'm blitzt.

As for your other question on switching out, it would help to know exactly what you are using to give an answer.

I used 10 28w t5ho, 5 warm Phillips silhouette(2500k) t5ho, and 5 cool (Osram)Sylvania Pentron t5ho(5500k) for veg and I loved it. Not to mention the plants did too. these costs under 10 Euros too, and they have a really good light spectrum.
