The Quantum™ brand Q-Flashes with an X in the Part number are designed to run from a Pack like the Lumedyne brand. In order to plug in their black four pin plug into the Lumedyne metal six pin socket, then you need an adapter like this one.
It's true that Quantum™ also sells their own version of this adapter cable, however, we use a better strain relief system that helps prevent clamping the cable into a short circuit and perhaps damaging some electronics.
This 400ws Pack is designed to power one Quantum Q-Flash™ model X flash head (of any generation number) directly without needing any additional adapters because it has a Quantum™ style head jack on it already. It can power a second Q-Flash™ (while using the QF-42 or the HCQQ cable adapters) or a full power Lumedyne Head with the second head jack.
It offers a recycle time twice as fast as the Quantum Qpaq-X™ and has all of the 400ws in one module. It connects to all generations and styles of Lumedyne Batteries and can be powered by our AC Power Supplies.
It has super simple operation with power on/off, speed of recycling and battery gauge push buttons.
