i've been looking at the alienbees b400, b800, and b1600 and am kind of intrigued by them since they can connect to battery packs allowing them to be used on location. my current lighting set up usually is an sb80dx flash, which works well, but it lacks the power to be used outside during the mid-day sun i'm finding out. sometimes i have to be at my max synch speed (1/250th) and around f/10, and at full power my flash can't put out enough output to light my subject well. my question is if i were to get say a b800 and the vagabond power pack, would i be able to shoot at f/10 and above with power to spare? it would be a decent investment but in my eyes it'd be worth it.
