  • 1Description

The white Distributed Dimming Series Source Four Jr Dimmer Retrofit Kit from ETC is designed to retrofit an existing Source Four Jr / Jr Zoom Fixture and comes with a burner assembly. It also includes a lamp housing.

The Source Four Dimmer delivers a high performance in tungsten-lighting applications. Using ETC’s ES (Electronic Silent) technology and a convection-cooled design, this dimmer can be placed in acoustically sensitive venues. By taking DMX control signals directly, this self dimming tungsten fixture can reside alongside LEDs and moving lights, allowing system designs to focus on switched power and data distribution instead of centralized dimming systems.

The Source Four Dimmer can be used in applications requiring distributed dimming and position flexibility such as theaters, hybrid incandescent, LED and discharge systems, industrial productions, rentals, conference and exhibition centers, and multi-use venues like schools and meeting rooms.

Mounting Flexibility

Yoke-mount; universal-mounting bracket included
Direct-mounting on a fixture yoke in multiple orientations to accommodate maximum flexibility
