ETC Source Four Leko, 19 Degree

The ETC Source Four Leko (19 Degree) is an ellipsoidal spotlight built for precise, controllable front light, gobo projection, and shuttered cuts in theatres, houses of worship, schools, and live event rigs. This fixture pairs the standard Source Four ellipsoidal head with a 19 degree lens tube for a tighter beam and longer throws where you need crisp edge control and consistent focus.

These ETC Source Four Lekos were used in a rental inventory. They show cosmetic wear and are in good working condition.

Please note that these items may have a longer lead time.

Rated up to 750W, the Source Four uses the super-efficient HPL lamp with a faceted dichroic reflector designed to remove 90% of IR heat from the beam. In practical terms, that means a cooler beam that helps extend gel life, protects patterns, and reduces heat on performers and scenery.

Optics and Beam Control

The 19 degree lens tube delivers a more concentrated field for punchy specials and clean projections. A rotating barrel (plus or minus 25 degrees) makes it easier to align shutters and patterns to your stage geometry, and the three-plane stainless-steel shutter blade assembly supports sharp, repeatable cuts.

Service-Friendly, Road-Ready Design

Built with rugged die-cast aluminum construction, the Source Four is designed for daily use in permanent installs and rental environments. Tool-free lamp adjustment helps speed focusing and maintenance calls, and an insulated rear handle improves handling during hang and strike.

System Compatibility

Interchangeable lens tubes let you reconfigure beam spread with other Source Four tubes (such as 26, 36, or 50 degree) when your plot changes. The fixture also supports Dimmer Doubling (North America only) for systems that use that capability.
