ETC Source Four Jr. 50-Degree Ellipsoidal with ES750 Silent Dimmer

Source Four Jr. 50-Degree Ellipsoidal

Compared to many conventional 650W and 1000W ellipsoidal spotlights, Source Four jr's 575 watts still deliver an even brighter light and offer the flexibility of multiple HPL lamp options and interchangeable lenses. The Source Four jr is perfect for -- but never limited to -- smaller theater venues, churches, schools, industrials, and any other application where affordability, space-savings and great performance are the criteria.

ES750 Silent Dimmer

Using ETC’s Electronic Silent* (ES) technology and a convection cooled design, this high-performance dimmer can be used with any 750W or less tungsten fixture. By taking DMX control signals directly, this self-dimming tungsten fixture can now reside alongside LEDs and moving lights, allowing system designs to focus on switched power and data distribution instead of centralized dimming systems.
