Overview
The 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.
