Depends on a few things.
If you use the full 10 feet you can squish 220 in there so 55 per bulb max(providing you use the 1 gal grow bags I do). I like to pack em tight then once they stop stretching take out 20 of the weakest ones. So you double that and you need between 400 and 440 if you are doing a flip flop system like I do.(2 rooms, 4 ballasts on relays, 8 bulbs)
I'm going to post pics of one I'm setting up right now in the morning. Bed time.
