Re: How much brighter are studio strobes than speedlights?

The lit circle seems to be comparable between the two lights, I think the 7-inch reflector has an 80-degree spread, so the 35mm zoom on the SB-900 shouldn't be any tighter than that, I wouldn't think.

Yes, I should try a flash meter to see if I can repro Paul Buff's numbers here:

My X2400 is pretty old, I wonder if these lights gradually lose output over time?
