The RBA S - 160 LED Continuous/Strobe Flash (for T11 2.5, T11 2.5i, T11 Vision and T20r LED Photo Booth Shell) is a lightweight moonlight, compact and powerful lighting accessory designed to enhance your photo experience with features that make it ideal for most applications. The 160-watt strobe flash features a bright LED modeling lamp that is maintenance-free. And instead of lasting 100 hours, the LED typically lasts approximately 25,000 hours. The RBA S - 160 has a built-in optical slave for wireless triggering, a sync cord for direct firing from your camera, a built-in umbrella receptacle, and a 5/8" standard stand mount. It accepts Impact's 50 x 50 cm (FF-SB50) and 50 x 70 cm (FF-SB70) Softboxes without a speed ring thanks to the head's built-in flex rod holes. An easy-to-mount barndoor set with filters, filter frame, and a honeycomb grid (SF-BDK) are available as optional accessories, as is a snoot (SF-SNT) with its own removable grid. Selectable flash output is full and 1/2 power.
