With the ETC Source Four 15-30° 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, 20A Twist-Lock model has all the advantages of the revolutionary fixed-focus Source Four: 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 4 models. Other models in this and the wider 25-50° zoom range are available:
Edison plug, Stage Pin, 15A Twist-Lock, and Pigtail.

When fitted with a 750W HPL bulb (available separately), this fixture will provide a beam of 117 footcandles 14.5' in diameter, from a distance of  55', @ 15° zoom. It will throw a beam of
54 footcandles 24.1 ' in diameter from 45', @ 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.

Solid Construction

Die-cast aluminum construction, 20 gauge stainless steel focusing shutters in a 25° rotating assembly will provide many years of dependable service.

Efficient Use of Energy

Other focusing tubes are available.
An optional iris is available.
