I am considering a monolight in the range of 800-860 wattseconds for high speed sync to photograph 7-10 people in a 500-700 square foot room because I assume that would be powerful enough for 10-15 feet away from the subjects in that large of a room. The question I have is how much would a single small off-camera speedlight (like the sb600--sb910) have in addition to that monolight in that setting in that sized room?
