The ellipsoidal fixture that changed the lighting industry

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.

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.
