The Next Generation Power Packs offer the familiar simple controls that have been available from Lumedyne for over thirty years. Enhanced manufacturing techniques allow Lumedyne to offer greater reliability and accurate 7 light Battery power level indications.
This power pack features an extra fast recycling time -- 2.5 seconds @ 400 w/s, 1.5 seconds @ 200 w/s and .8 second @ 100 w/s. Also, flash duration has been shortened to 1/1500 second for those photographers who shoot with leaf-shutter cameras in bright ambient light. These features make this pack suitable for most sports events, and fashion runway photography. It is backward compatible with all Classic flash heads.
Note: Not compatible with Boosters, AC Adapter, Small Battery (BSML), Automatic, or Speed Modules.
Note: The usual number of flashes per charge of any Lumedyne battery used with this pack will be diminished by 30%.
