With the ETC Source Four 25-50° Zoom Ellipsoidal Spotlight only one fixture is needed for a variety of field angles. ETC's patented one-handed zoom operation makes adjustments quick, simple and safe. A technician can focus with one hand and hold the ladder with the other. The lens-tube door provides quick, tool-free access when cleaning the lens assembly.
This White, 20 Amp Twist-Lock model has all the advantages of the revolutionary fixed-focus Source 4: bright, even field, cool beam, and amazing efficiency. The patented dichroic mirror disperses heat; shutters and accessories stay cool. Drop-in accessories are interchangeable with the fixed-focus Source Four models. Other models in this and the narrower 15-30° zoom range are available: Edison plug, 15 Amp Twist-Lock, and Pigtail.
When fitted with a 750 watt HPL bulb (available separately), this fixture will provide a beam of 127 footcandles 15.5 ft in diameter, from a distance of 35 ft, @ 25° zoom. It will throw a beam of 49 footcandles 32.6 ft in diameter from the same distance @ 50° zoom.
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.
The white finish of the fixture and accessories calls less attention to itself when used in architectural applications.
Die-cast aluminum construction, 20 gauge stainless steel focusing shutters in a 25° rotating assembly will provide many years of dependable service.
