LED36

Small in size, yet surprisingly powerful, the MM-LED-36 On-Camera LED Video Light from Mela Mount uses 36 daylight-balanced LEDs to provide the equivalent output of a 40-watt bulb while being powered by only three AAA batteries. The unit will run for up to 2 hours on a set of AAA batteries.
The integrated diffusion filter softens the light reducing hot spots. The unit slides into your camera's cold shoe, and the locking ring secures it in place. Built-in slots on the top and sides of the unit allow you to mount an additional MM-LED-36 (not included) to your main unit creating a multi-unit light array.
