Source Four Dimmer Kit, Black


Product shown in image is for illustrative purposes only. Actual product is the lamp base dimmer kit only. Source Four lights and accessories are not included.

The Source Four Dimmer offers a new standard in high-performance tungsten-lighting applications with an integrated dimmer. Using ETC’s Electronic Silent* (ES) technology and a convection-cooled design, this high-performance dimmer can be placed in acousticallysensitive venues. By taking DMX control signals directly, this selfdimming tungsten fixture can now reside alongside LEDs and moving lights, allowing system designs to focus on switched power and data distribution instead of centralized dimming systems.
