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. Applications requiring distributed dimming and position flexibility, theatres, hybrid incandescent, LED and discharge systems, industrial productions, rentals, conference and exhibition centers, multi-use venues such as schools and meeting rooms.
