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, Pigtail plug 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, 15, 20A Twist-Lock, and Stage Pin.

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.

Subtle Appearance

The white finish of the fixture and accessories calls less attention to itself when used in architectural applications.

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

The special HPL bulb, and borosilicate reflector provide more lumens per watt: at 575W the Source Four literally outshines other brands' 1000W ellipsoidals. At 750W, no other ellipsoidal can compare to this fixture.


The steel yoke has 2 mounting position choices.
Fixture has 2 accessory slots, and a top-mounted gel frame retainer.
Other focusing tubes are available.
An optional iris is available.

Scale Markings

Field angle and focus settings are provided on the fixture.

Easy Calibration

Tool-free lamp centering and peak/flat adjustment knobs are built in.

Is there any difference between the light coming from an ETC Source 4 with a 50 degree fixed lens and an ETC Source 4 Zoom in the 50 degree setting? Perhaps a difference in output/brightness, contrast, crispiness, or hue?
