While this is true, wouldn't each monolight be heavier because they have their own power supply? So instead of 4 little power supplies, you carry one big one?
As far as cables, you run one to the wall(or battery pack) or to the head. No getting around a power cable for each unit.
Taylor, using AB800 as an example, four of them weigh a total of 12 lbs. for 1300 w-s total. On the other hand, four (light weight) Dynalite 2040 heads weigh 8 lbs., and the 1000 w-s pack weighs 6 lbs. (total 14+ lbs.) and most comparable packs and heads are heavier than Dynalites.
