#1. "RE: Alien Bees for Reception and photo booth" In response to In response to 0
Your question is more complicated than it looks.
In my somewhat limited studio experience, I discovered that there is no "one size fits all" strobe that will work in all situations.
For a very large hall, where you can bounce the light off the ceiling, a more powerfull unit may be required, e.g., 800 WS or 1,600 WS. These units may be overkill for the small studio or booth settings, as you may not be able to dial the power level down far enough to be useful, even at smallest apertures and lowest possible ISO figures.
A few years ago, I purchased four relatively inexpensive 300 WS units that can be used successfully in smaller venues.
Depending on brand and relative cost, studio units will usually recycle fairly rapidly, even at full power. Check the specs before making your final decision.
Perhaps some of our professional wedding photographers will offer more detailed advice.
