3 foot tank lighting ?

I am currently assembling a 3" (45 tall) plant tank. I have the c02 equipment
and dupla cables. However, I am unsure as to how to light the tank. Any
thoughts on using 4/ea 30 watt full spectrum bulbs vs. 2/ea HO or VHO ?

I don't have any experience with HO lamps. Do they last as long? Are they
worth the price?
