Source Four Fresnel w/ attached Dimmer

ETC combines the efficiency of the HPL lamp with the singular optical qualities of the fresnel optical system to create the truly advanced ETC Source Four Fresnel. Traditional fresnel optics provide a unique quality of blending wash light and beam shaping via barn doors for well-defined, soft-edged area lighting. The Source Four Fresnel combines this classic system with a unique reflector design enabling the HPL 750W-equipped Source Four Fresnel to equal the lumen output of other 1000W fresnel fixtures. Spot-to-flood focus is accomplished by large, easy-to-use knob for quick adjustments in inconvenient positions. The unique Quick eXchange socket design permits re-lamping from underneath the fixture without breaking focus in most situations.

DIMMER

The Source Four Dimmer offers a new standard in high-performance tungsten-lighting applications with an integrated dimmer. Using ETC’s Electronic Silent* (ES) technology and a convection-cooled design, this 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.
