The 25-50° Source Four Junior Zoom 575W Black Ellipsoidal Spotlight with 20A Twist Lock plug combines the energy-saving power of the patented HPL lamp, with a dichroic reflector and optical-quality lenses. Source Four technology provides a clean white beam for unequaled imaging, crisp pattern projection, and a bright, even field.


The Source Four Jr Zoom is best for use on the small stage or in clubs, retail events and industrials. It boasts rugged ETC fixture construction and all the precision optics of a Source Four.

When fitted with a 575W HPL bulb (available separately), this fixture will provide a beam of 
88 footcandles 13.2' (4.2 m) in diameter, from a distance of 30' (9 m) @ 25° zoom. It will throw 
63 footcandles 17.8' (5.4 m) in diameter, from a distance of 20' (6 m) @ 50° zoom.

This model includes a 20A Twist-Lock connector. Other models are available, with Pigtail, 3 prong Edison Power Plug, and Stage Pin connectors.

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.
