There are four Deluxe Heads to choose from. There is an option for having a Quantum style TTL connecter or Metz style TTL connecter.
While both styles are made otherwise exactly the same, there is also a choice of an 800ws Flashtube or a 2400ws Flashtube. The Tube is easily exchanged so we only recommend the 2400ws Head when you know that you will exceed the 800ws limitation of the normal Flashtube.
All Signature Series Heads have a Modeling Light and Test Fire Button with Dual Sync connections (USA and European types). All have the removable two position Reflector and include two diffusers and a snoot. All have dual 1/4-20 threaded mounts and a metal frame.
The Deluxe Heads also have the TTL connector of choice and an Adjustable Audible Ready Indicator.
Please note, even though the Heads can go up to 2400ws, the maximum power that the current TTL Modules can accurately control is between 800ws and 1600ws depending on the camera and Module.
