The world’s first AC and battery-powered TTL/HSS monolight in one package. Color accurate with short flash duration.

Product Highlights:

• AC & DC - AC Power when you want it, DC Battery when you need it (AC sold separately)
• TTL metering for automatic flash exposure
• High-Speed Sync up to 1/8000th of a second
• Color accuracy to within 100K throughout the power range
• 9-Stop power range adjustable within 1/10th of a stop

The S1 is the first high-tech TTL HSS monolight to include intelligent TTL and HSS technology in a battery-powered monolight with an available International Multi-Voltage AC Power adapter.

• Through The Lens Metering in TTL Mode uses the S1’s entire 9-stop power range (500W – 1.9Ws) and is automatically calculated in 1/10th stop increments, and allows for ± 3 stops of exposure compensation
• Manual Mode utilizes 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 of the power range (10.0 – 8.0) and is manually adjustable in 1/10-stop increments
• Available International Multi-Voltage AC Adapter that can power the unit with or without the battery in place, maximizing battery health longevity
• Integrated and exchangeable lithium-ion battery is flush with the flash body, offers a 350 full power flash capacity and allows for wire-free and rapid setup and repositioning of lights when power outlets encumber workflow or are not an option at a shoot
• Color Accurate to within ±100 Kelvin using high-tech insulated-gate bipolar transistor (IGBT) technology
• Short Flash Duration for freezing action and sports motion between 1/500th of a second to 1/11000th without compromising color consistency, 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
