The Source Four is the only fixture combining the energy-saving power of the HPL lamp with the dichroic reflector for the coolest beam on the market. Gels, patterns, and shutters last longer, and your performance space stays cooler. The Source Four gives you a clean white beam for crisp pattern projection, and a bright, even field. Rated for up to 750 watts, the Source Four is perfect for punching through saturated colors and performing the longest throws. Ultra-efficient for more lumens per watt: at 575 watts the Source Four shines brighter than 1000W ellipsoidals.
