ETC Source Four Leko, 36 Degree

These ETC Source Four Lekos have minor wear and are in good working condition. 36 degree lens tubes are included with these units. Stage pin connectors are used on the power cables.

The ETC Source Four (Source 4) Leko is a workhorse ellipsoidal spotlight for theaters, studios, houses of worship, and live events where you need clean projection, controlled beam shaping, and consistent focus. This configuration uses a 36 degree lens tube, a versatile option for medium-throw front light, specials, and gobo projection, helping you balance coverage and intensity without excessive spill.

Optics and Beam Control

The Source Four pairs the energy-saving HPL lamp with a faceted dichroic reflector and optical quality lenses to produce a bright, efficient beam while removing 90% of IR heat from the light path. In practical use, that means gels, patterns, and shutters tend to last longer, and your performance space stays cooler.

Built for Focus and Repeatability

Designed for day-to-day production use, the fixture includes a rotating barrel (plus or minus 25 degrees) for quick alignment, a three-plane stainless-steel shutter blade assembly for crisp cuts, and tool-free lamp adjustment to help maintain output and focus. Rugged die-cast aluminum construction and an insulated rear handle support reliable handling during hang, focus, and strike.

System Flexibility

The Source Four platform supports interchangeable lens tubes (19, 26, 36, or 50 degree) to adapt to different throws and coverage needs, and it supports Dimmer Doubling (North America only) for more flexible dimmer utilization in compatible systems. Source Four fixtures are shipped brand new with a c-clamp, color frame, and a slot for either a drop-in iris or motorized pattern device. Three-foot, three-wire Teflon leads with bare ends encased in black fiberglass tubing are shipped as standard.

Rated up to 750W, this Source Four Leko is a dependable choice for inventory expansions, rep plots, and venues standardizing on a widely supported ellipsoidal ecosystem.
