cheapest route is compact fluorescents. Go towal-mart or home depot and get some higher wattage cfl's with an output in the 1600 lumen region. (I think that's the highest wal-mart has) Make sure that they're the cool light kind (6500k). The ideal situation is the more light the merrier, but you can get away with 5 or so for a while. After a bit you'll need more light if you want a good yield. I think those bulbs are like $7 apiece. I don't know of any that run off batteries( but then again I haven't been in the growing field for very long) but you can get the halo reflectors that plug into a wall socket.
