Hi all. As a X LD i have played with a bunch of different strobe units. I however have not played with those monsters. WOW!! And the cdrh freaks out about anything above 5mwGlad they don't know about these!!
Anyway I have used the martin strobe lots and like it very much. It is plenty bright and pretty cheap.

During a show they live a lot longer than the data flash, before the thermal time out kicks in.
