ETC Source Four Leko, 50 Degree

These ETC Source Four Lekos have minor wear and are in good working condition. 50 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 front light, specials, and general stage coverage. This unit pairs the standard Source Four ellipsoidal head with a 50 degree lens tube for a wider field angle, making it a practical choice when you need broad coverage from shorter throws in theaters, houses of worship, and event spaces.

Optical Performance and Cooler Beam

Built around the super-efficient HPL lamp system, the Source Four uses a faceted dichroic reflector to remove 90% of IR heat from the beam. In day-to-day use, that means gels, patterns, and shutters typically last longer, and less heat is pushed toward performers and scenic elements.

Focus Control for Repertory and Touring Use

The rotating barrel (plus or minus 25 degrees) and three-plane stainless-steel shutter assembly make it easy to shape and clean up the beam for crisp edges on scenery, soft-edged area lighting, or tight specials. Tool-free lamp adjustment helps you maintain consistent output and a clean field without slowing down changeovers.

System Flexibility and Build

Rated up to 750W and housed in rugged die-cast aluminum, the Source Four is designed for regular hang, strike, and refocus. The interchangeable lens tube system supports the common Source Four tube options (19, 26, 36, or 50 degree) when you need to reconfigure beam spread across a rep plot. North American installations can also take advantage of Dimmer Doubling support where applicable.
