Welcome. This listing is for a Speedotron 1500ws Flash Unit with Juice Box. This is a battery powered flash generator that works with Speedotron Black line light heads (not included). Both the power pack generator and the juice box battery pack have been tested and are working. This unit comes with a Tenba air case capable of holding the 1500 with enough interior space for an additional 103 light head (not included). A nice portable rig that doesn’t require being tethered to an AC outlet.
