The Vidpro LED-144 Camcorder DSLR Light Kit is an on-camera LED light that's 5.5 x 3.5" in size and features 144 warm-to-the-touch LED bulbs. A ball mount is included for mounting the light onto your camera, and is adjustable to rotate in various directions. A dial on the back of the light lets you select between different color temperatures from 5600K daylight to 3200K tungsten, and another dial lets you set brightness from 100 - 10%. For smoothing out contrast and reducing shadows, a white diffuser is supplied that snaps onto the light magnetically and serves to soften and spread out the light output.
