ETC SOURCE 4 LENS TUBE (STANDARD)
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.
ETC lens tubes ship with the color frame and focus knob.
