Canon 580EX II vs Alien Bees 400 comparison test

I just purchased a couple AB 400’s, and I wanted to see a real life, light output, comparison between the Canon 580EX II, and the AB’s.  I shot the below shots mid day, sunny, in the shade.  I metered without strobes, and set the exposure at -2 stops (ISO 200, F13, 1/200, 16mm lens), and then set the 580EX II at 1/1 (on manual), and full power on the AB 400’s.  I stood approximately 12′ – 15′ away from the strobes.  All strobes were lined up side by side.

Here’s the AB 400 with the Long Throw 11″ reflector:

Here’s two AB 400’s.  One with the 11″ long throw reflector, and one with the stock 7″ reflector:
