The black Source Four Lighting Fixture with Dimmer and Stage Pin Connector from ETC combines the energy-saving power of the patented HPL lamp (sold separately), with a dichroic reflector and optical-quality lenses (sold separately), for a cooler operating light. That means your gels, patterns and shutters last longer and your performance space stays cooler.
The 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 (sold separately) for 19º, 26º, 36º and 50º field angles makes the Source Four better for ultra-crisp, high-contrast gobo projections.
Rated for up to 750W, the Source Four is great for punching through saturated colors and performing the longest throws. Ultra-efficient for more lumens per watt. At 575 watts the Source Four is brighter then conventional 1000w ellipsoidals. At 750 watts the Source Four is one of the brightest fixtures available in its class.
