PRODUCT DESCRIPTION
ETC Source 4 Zoom 25-50 Degree 42550
With Source Four Zoom you only need one fixture for a variety of field angles. Plus, Source Four Zoom makes it easy: ETC's patented one-handed zoom operation makes adjustments quick, simple and safe. Technicians can focus with one hand and hold the ladder with the other. And the lens-tube door provides quick and easy access when you want to clean the lens assembly (tool-free!). But the best part is that Source Four Zoom has all the advantages of the revolutionary fixed-focus Source Four: bright, even field, cool beam, and amazing efficiency. The patented dichroic mirror means shutters and accessories stay cool, and drop-in accessories are interchangeable with fixed-focus Source Fours. Rated up to 750W, Source Four Zoom gives you Source Four's crisp optics for excellent imaging and field quality.
ETC Source Four Zooms are supplied with color frame, C-clamp and 36 inch electrical lead.(Bulb, Safety Cable, Pattern Holder and Power Connector NOT INCLUDED!!)
