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 acoustically- sensitive venues. By taking DMX control signals directly, this self-dimming 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.
