ETC Source 4
The 50° Source 4 750 Watt Black Ellipsoidal Spotlight with 3 prong Edison Plug combines the energy-saving power of the patented HPL lamp, with a dichroic reflector and optical-quality lenses. Source 4 technology provides a clean white beam for unequaled imaging, crisp pattern projection, and a bright, even field.
Rated for 375, 575 or 750 watts, the Source 4 is perfect for punching through saturated colors and providing the longest throws. The optional EDLT lens tubes for 19, 26, 36 and 50° field angle models make the Source Four even better for ultra-crisp, high-contrast gobo projections.
When fitted with a 750 watt HPL bulb (available separately), this fixture will provide a beam of 349 footcandles 9.5 ft (2.9 m) in diameter, from a distance of 10 ft (3 m). It will throw 56 footcandles 23.8 ft (7.1 m) in diameter, from a distance of 75 ft (22.7 m).
This model includes a 3 prong Edison Power Plug.
Thermally insulated rear handle, knobs and shutter handles, and heat-sink lamp socket make handling and aiming easier; gels, patterns and shutters last longer, and your performance space stays cooler.
Die-cast aluminum construction, 20 gauge stainless steel focusing shutters in a 25° rotating assembly will provide many years of dependable service.
