ETC Source Four Zoom 25-50 Zoom Ellipsoidal
ETC Source Four Zoom 25-50 Zoom Ellipsoidal
There’s only one Source Four – the ellipsoidal fixture that changed the lighting industry. Source Four combines the energy-saving power of the patented HPL lamp, with a dichroic reflector and optical-quality lenses, for the coolest beam on the market. That means your gels, patterns and shutters last longer and your performance space stays cooler. Maximum brightness, maximum field-angle flexibility. With Source Four® Zoom you only need one fixture for a variety of field angles. Plus, Source Four Zoom makes it easy: ETC’s patented one-handed zoom operation makes adjustments quick, simple and safe. Technicians can focus with one hand and hold the ladder with the other.
