The Savage Luminous Pro On-Camera Bi-Color LED Light features variable color temperature, a built-in dimmer, AC/DC power, an onboard battery, and a battery power remaining indicator. You can power the camera via the included power supply or from the included L-series type battery. The light mounts to your camera with a removable shoe mount. The shoe mount incorporates a threaded 1/4"-20 mounting hole, and it can be mounted on either side as well as the top or bottom of the light. Individual knobs allow you to control both the color temperature and the brightness of the fixture.
