The Lumedyne ZK40 400W/s Basic Fast Kit was put together by B&H to provide a basic road kit for location shooters. It is backward compatible with boosters, high speed modules, chargers and flash heads. Existing heads plug directly into the pack, while the Signature Series heads use an extension cord or head cable to plug into the pack.
The Basic Pack offers a 4-light battery gauge and 7 F-stops of manual control through one or two flash heads. It operates with one main control and an On/Off button for the battery gauge. This pack is for manual exposures or can be teamed up with an Auto Module for an automatic F-stop selection. The head included in this kit has a 25W modeling light, and can handle up to 800W/s of stored power.
