ETC Source Four Leko, 10 Degree

These ETC Source Four Lekos show minor wear and are in good working condition. 10 degree lens tubes are included with these fixtures. Stage pin connectors are used on the power cables.

The ETC Source Four (Source 4) 10 Degree is an ellipsoidal spotlight built for precise, long-throw focusing in theatres, houses of worship, studios, and touring rigs. Pairing a standard Source Four ellipsoidal head with a 10 degree lens tube, it’s designed for tight beams, crisp shutter cuts, and clean projection of gobos and patterns where accuracy matters.

Optics and Beam Control

Source Four's revolutionary technology gives you a clean white beam for unequaled imaging, crisp pattern projection, and a bright, even field. 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. A faceted dichroic reflector removes 90% of IR heat from the beam, helping reduce heat on performers and scenic elements while keeping light output usable and consistent.

Focus, Serviceability, and Build

Designed for fast work on the ladder or catwalk, the fixture includes tool-free lamp adjustment and an insulated rear handle for safer handling during focusing. The rotating barrel (25 degrees) and three-plane stainless-steel shutter blade assembly support repeatable framing and clean cuts, and the rugged die-cast aluminum construction is built to hold up under frequent changeovers.

Power and System Flexibility

Rated up to 750W with a super-efficient HPL lamp, the Source Four platform is also designed around interchangeable lens tubes, making it easy to reconfigure beam angles across compatible Source Four optics as your plot changes.
