  • hi how many full power pops you get from the

    • David Selby

      200 flashes at 300J and 100 at 600J according to the seller.

  • does anybody know the t.1 flash duration at full power of these unit ??

  • I friend bought a 3 set of 600ADs with power packs we’ve used them on location during wedding shoots and tomorrow night i am going to use them for group shots at an engagement party, so far they work well and very good at the price

  • I have 300 and 600J flash and it dit not freeze action like I want to…

    My speedlight is more efficient for freezing action than this more powerfull flashes. I don’t know why …

    • David A. Selby

      Speedlights are, by design, much quicker than more powerful flashes. Only since quite recently can you get monolights with fast flash durations.

  • Ryan

    The flash duration is long … I start to lose flash power with a shutter speed faster than 1/80th. At full sync speed of a 70D (1/250th) I’ve lost about 2 stops. This is in the dark room with no ambient light, f8, ISO 100 etc.
