Light Output and Beam Control

The Source Four combines the energy saving power of the HPL lamp with a faceted dichroic reflector that removes 90% of IR heat from the beam. In practical use, that helps keep gels, gobos, and shutters cooler for longer life, and it reduces heat in the performance space. The included 36 degree lens tube provides a versatile beam angle that works well for medium-throw applications where you need coverage with definition.

Built for Focus, Adjustments, and Daily Use

For fast setup and repeatable results, the fixture includes a rotating barrel (plus or minus 25 degrees) and a three-plane stainless-steel shutter blade assembly for crisp shaping. Tool-free lamp adjustment helps you dial in the beam without slowing down calls, and the insulated rear handle makes repositioning safer during load-ins and focus sessions.

System Compatibility and Rigging Flexibility

The ETC Source Four platform supports interchangeable lens tubes (19, 26, 36, or 50 degree), making it easy to standardize on a single fixture body and swap optics to match different throws and trims. It is rated up to 750W, built from rugged die-cast aluminum, and supports Dimmer Doubling (North America only) for installations using compatible dimming systems.
