Light, in every way
The Nikon LD-1000 LED movie light is a slightly diffused continuous light source designed to improve the quality of your videos (and photos) in low-light situations. It screws directly into the tripod socket of your Nikon 1 or Coolpix camera, and the light itself sits off to the side of your lens' axis, so the shadows that it casts look pleasing and natural. Two brightness settings allow you to adjust the amount of lighting support that you need.
The LD-1000 is battery-powered, compact, and lightweight, so you'll find it an easy travel companion.
