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.

Since its introduction in 1992, barring a few minor tweaks, ETC has maintained the original design of the Source 4 ERS (Elliptical Reflector Spotlight).

For that reason, there is literally nothing on a Source 4 which cannot be repaired or replaced.
