ETC Source Four jr Overview

The ETC Source Four jr Fixture with 36° Lens and Dimmer (Stage Pin Connector, Black) offers many of the same features as the larger Source Four fixtures in a smaller package. This version of the Source Four jr light comes with a 36° lens and dimmer. Despite only being 575 watts the Source Four jr is brighter than many conventional 650W and 1000W ellipsoidal spotlights. The Source Four jr is suitable for but not limited to smaller theatre venues, churches, schools, industrials, and any other application where affordability, space-savings and great performance are the criteria.

Using the electronic Silent (eS) technology and a convection-cooled design, the attached high-performance dimmer can be placed in acoustically sensitive venues. 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.
