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 Black, Pigtail 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 and 20 Amp Twist-Lock, and Stage-Pin.

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.

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 575 watts the Source Four literally outshines other brands' 1000W ellipsoidals. At 750 watts, 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.
