The 490 Source Four from ETC is a 90-degree ellipsoidal that 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.

There's only one Source Four - the ellipsoidal fixture that changed the lighting industry. 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 19°, 26°, 36° and 50° field angles makes the Source Four even better for ultra-crisp, high-contrast gobo projections.
