ETC Source Four 750W

About the ETC Source Four 750W

The ETC Source Four 750W is one of the most respected ellipsoidal reflector spotlights (ERS) in the professional lighting industry. Manufactured by ETC (Electronic Theatre Controls), the Source Four redefined the standard for theatrical and production fixtures when it was introduced, and it remains a benchmark tool for lighting designers worldwide. Powered by a 750W HPL lamp, it delivers bright, punchy output with excellent colour rendering and an exceptionally even field, making it suitable for everything from tight specials to wide washes depending on your chosen lens tube.

At the heart of the fixture is ETC’s patented faceted dichroic reflector, which removes approximately 90% of infrared heat from the beam. This significantly extends the life of gels, gobos, and irises, and keeps the optical train cooler during long performance runs, a critical advantage in repertory theatre and extended events.

Optical Performance & Flexibility

The Source Four’s interchangeable lens tube system gives it exceptional versatility. Lens tubes are available in nine field angle options, from a tight 5° for long-throw specials through to a wide 90° for short-throw flood coverage, allowing the same body to serve vastly different positions in a rig. For applications requiring precise gobo projection, the Enhanced Definition Lens Tube (EDLT) delivers sharper edges, higher contrast, and improved definition compared to the standard lens tube, making it the preferred choice for projection work in theatre, corporate presentations, and scenic breakups on film and television sets.

The 6.25-inch colour frame size is an industry standard, ensuring broad compatibility with gels, diffusion, and accessories from all major manufacturers. Four internal shutters allow precise beam shaping, and the unit accepts standard irises, gobos, and drop-in accessories via the accessory slot.

Applications in Live Production

The Source Four 750W is a workhorse fixture across a wide range of professional production contexts. In theatre, it excels as a front-of-house special, key light, or gobo projector. On live music and festival stages, it provides reliable, high-output beam control for front lighting and hard-edged specials. In film and television environments, the clean, spectrally consistent output of the HPL source pairs well with camera sensors and suits colour correction workflows. For corporate and exhibition events, the EDLT lens tube makes it ideal for projecting logos, patterns, or breakup gobos across scenic elements.
