Name: ETC 7" Source Four Fresnel with Dimmer (Bare Power Lead, White)
Brand: ETC
SKU: ETS4F7DW
Price: 925.00 USD

The ETC 7" Source Four Fresnel with Dimmer (Bare Power Lead, White) combines the efficiency of the HPL lamp with the singular optical qualities of the Fresnel optical system. The traditional Fresnel optics provides a unique quality of blending wash light and beam shaping via barn doors for well-defined, soft-edged area lighting. The 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. The 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.

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.
