NEW ETC Source Four 5 Degree Lens Tube

The NEW ETC Source Four 5 Degree Lens Tube is a narrow-beam ellipsoidal lens tube designed for long-throw, precision stage and architectural lighting where tight focus and clean shutter cuts matter. It pairs optical-quality lenses with the Source Four’s proven ellipsoidal design to deliver a controlled beam that holds up well for detailed specials, highlights, and long-distance front-of-house positions.

Optics and beam control for long throws

With a 5 degree field angle, this lens tube is built for applications that demand a concentrated beam and accurate beam shaping. The Source Four optical system 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.

Built for production environments

Its rugged die-cast aluminum construction is designed to stand up to regular handling in venues, rental inventories, and touring-style workflows, while maintaining consistent alignment and performance.
