Lighting Products and Fixtures Design Sprocket Light Lighting Fixture Chandelier by Maurice L. Dery Sprocket is a unique lighting design that is a scaled replica of a Gear and Chain. The illumination of this product uses energy efficient Leds. Custom isolators were designed and developed for this project. This enables the light fixture to be suspended without any visible power cords. The chain portion of the light can be manipulated into different layouts, as it is modular in design.
