Operates from a Super or Ultra Battery. 50% Faster than older HSMs made a few years ago. Recycles twice as fast as most packs alone. Two 054Xs can be combined with an Ultra Battery for the same recycling times as the 054Z unit alone. High Speed Modules allow you to make the recycling times faster than any other brand of portable flashes at any power level offered.
HSMs speeds up the recycle for any power pack
Only use HSMs with larger Batteries- Never a Mini or a Regular
The Vehicle Battery Kompartment (029K) may be used with HSMs, with the same results obtained from a Ultra Battery
HSMs are not for use with the AC Supplies or Vehicle Adapters
Put the HSMs at the bottom of the system and the system automatically recycles faster in every setting.
