Interfit also offers the S1 in just a mains powered version. Of course, without the battery, this 500Ws head becomes very affordable while still retaining all of the other advanced features of its battery driven ""Big Brother"" like HSS, TTL, short flash duration and superb colour accuracy.

With this unit, called the S1A, we do not include a remote, so you will need to buy this separately. There is a choice of Canon, Nikon or Universal for cameras like Pentax or Olympus.
The S1A kit comes with seven inch-spill kill reflector and mains lead, and like the S1 is fully compatible with Bowens S-Type Accessories.

* Through The Lens Metering in TTL Mode uses the S1a's entire 9-stop power range (500W - 1.9Ws) and is automatically calculated in 1/10th stop increments, and allows for ? three stops of exposure compensation
* Manual Mode utilises the entire 9-stop power range, controllable in 1/10th stop increments
* High-Speed Sync in Manual Mode at up to 1/8000th of a second shutter speed using the top 3 stops in the power range and is manually adjustable in 1/10-stop increments
* Fast Recycle Time of only 2 seconds at full power allows for rapid shooting in a fast-paced studio environment.
* Colour Accurate to within ?100 Kelvin using high-tech insulated-gate bipolar transistor (IGBT) technology
* Short Flash Duration for freezing action and sports motion between 1/1000th of a second to 1/9000th depending on power output using IGBT technology.
* Integrated Wireless System with remote TTL flash exposure compensation and manual power control in three groups from camera position using the S1 Remotes for Canon, Nikon, or Sony (sold separately)
* Frosted Glass Dome softens and disperses light evenly through large and small light modifiers alike, from large octaboxes to small beauty dishes and reflectors while protecting the user-replaceable flash tube.
* Aluminum Construction with an attractive matte finish gives the unit greater heat dispersion, durability and weight-to-rigidity efficiency
* Firmware Upgradeable via Micro USB Port for future fixes and features
* Bowens? S-Type Mount is compatible with a large scope of adapter rings and modifiers such as softboxes, reflectors, and grids
