Well I'm looking into getting an A.C. Strobe sometime soon. I will be using it in a gym and will be bouncing it off the ceiling. My question is, how many watt seconds would I need? I was thinking of getting the Speedotron with 2400 Ws but on full power it has a flash duration of 1/225 seconds. And I think that would be too slow for freezing basketball action. So I have a price range of 400 bucks and about 45 of that will be going to an adorama 13 foot light stand. Any recommendations?
