The ETC Source Four 10 Degree Lens Tube is a 10 degree ellipsoidal lens tube designed for ETC Source Four fixtures, delivering a narrow, long-throw beam that helps place light precisely on small areas or distant targets in theatre, worship, and live event applications.
ETC Source Four 10 Degree Ellipsoidal Lens Tube. The Source Four is the fixture that changed the lighting industry. It combines the energy saving power of the HPL lamp with a dichroic reflector and optical quality lenses. These features combine to make the coolest beam available in an ellipsoidal- meaning gels, patterns, and shutters last longer and your performance space stays cooler.
The 10 degree optic is a practical choice when you need tight beam spread and clean focus, such as isolating a lectern, highlighting a performer from a catwalk or FOH position, or creating crisp gobo and shutter cuts from a distance.
This lens tube is intended for use with ETC Source Four ellipsoidal fixtures, making it a straightforward way to configure an existing Source Four for a narrower beam angle without changing your overall fixture ecosystem.
