On full power, these are a normal strength flash, (guide number 100) and about 1/1000 of a second with a few second recycle. At 1/32, they are 1/15500 sec, with a subsecond recycle time. I've also got a more expensive Nikon SB28 with similar flash durations, but it has a 1/64 mode and an auto repeat, where it will go to 40 hz or so for quite a few flashes. These can be triggered by connecting to the pc cord /port and shorting the two wires -- a pretty simple circuit that doesn't take the same sort of high power work and bare capacitors that the Make trigger circuit uses. One caveat here is that I don't know the lag from short to firing, it's either a spec somewhere or it's a trial and error thing.
