when to use a ballast?

Im doing a DIY 81 watt lighting system using 3 quad bulb pc. there 27 watts each and i was just wondering if i need to get some ballasts for them or not? If so would i need to get 3 ballasts or can i just get 1 big one?

While I am not an electronics person, I am pretty sure you need a ballast to run flourescents, period. If you don't I wold still want one just to fire the bubls off right instead of waiting for them to heat up.
