Fenix SD11 diving light is specifically designed for underwater photography and video shooting. The advanced “R ” mode is made for better color rendering with a combination of neutral white LED light and red LED light. R mode makes the SD11 an effective light for underwater viewing, photographing, video shooting and even photography on the shore since red light is extraordinarily scarce. Featuring a soft wide beam and R , SD11 is fit for both illumination and photography on shore or in water. In addition, the 100m waterproof classification, maximum 1000 lumens and low battery warning makes the SD11 perfect for the demands of safe deep diving photography. Easily choose output selection with the magnetic rotating ring while you are diving. The included flashlight clip and camera mount are compatible with most of the sports cameras and DSLRs.
