The ETC Source Four Ellipsoidal Lighting Fixture with Dimmer (25-50˚ Zoom, L5-20 Connector, White) features a rugged die-cast and extruded aluminum construction. With the patented one-handed zoom operation, adjustments are quick, simple and safe. Technicians can focus with one hand and hold the ladder with the other. And the lens-tube door provides quick and easy access when you want to clean the lens assembly, tool-free. The patented dichroic mirror allows shutters and accessories to stay cool, and drop-in accessories are interchangeable with fixed-focus fixtures. Rated up to 750W, Source Four Zoom gives you crisp optics for excellent imaging and field quality.
Using the electronic Silent (eS) technology and a convection-cooled design, the attached 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.
