4 lights just enough for 4 directions.Do note that if you need a lot of 'fire power', and are pushing the SB-900 near or at its max, and risking 'thermal cut-off', you may group up to 3 units of SB-900s and have them all fire together via the CLS. These three plus the one mounted on your camera makes a total of 4. I am sure this is enough 'fire power'.

i still need one more light source to complete.
