T5 can work fine. Or T 8 or 12. 5 is newest and most efficient, T12 is oldest technology and least efficient. Least costly.
In terms of bulbs, grow lights are most expensive. I like the full spectrum bulbs aka natural light.
LED is most expensive particularly in view of efficiency. Don't be fooled with some of the cheap junk out there.
CFL - the compact fluorescent is really coming down in price and are efficient for a small space bulb. I just built my own 800 watt equivalent dome/hood.
