The ETC 450 Source Four 50-Degree Ellipsoidal combines the energy-saving power of the patented HPL lamp with a dichroic reflector and optical-quality lenses. That means your gels, patterns and shutters last longer and your performance space stays cooler.
No other light offers such optical brilliance. Source Four's revolutionary technology gives you a clean white beam for unequaled imaging, crisp pattern projection, and a bright, even field. The EDLT lens tube option for 19º, 26º, 36º and 50º field angles makes the Source Four even better for ultra-crisp, high-contrast gobo projections.
