On my first grow, I just used some twist CFL bulbs. I bought an 8$ clamp light, some 3$ lamp splitters.. running 4 bulbs per clamp light. The yeild was decent for the little money invested. And the more actual wattage the better. You want bulbs in the 2700k range for flowering (soft white bulbs), 6500k for veg (daylight bulbs).

Good luck!
