The 50° Source Four Junior 575 Watt Black Ellipsoidal Spotlight with 20 Amp 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.

This wide-throw Source Four Jr is perfect for - but never limited to - smaller theatre venues, churches, schools, industrials, and any other application where affordability, space-savings and high performance are the criteria.

When fitted with a 575 watt HPL bulb (available separately), this fixture will provide a beam of
220 footcandles 9.3 ft (2.8 m) in diameter, from a distance of 10 ft (3.3 m).
It will throw 55 footcandles 18.6 ft (5.6 m) in diameter, from a distance of 20 ft (6 m).

This model includes a 20A Twist Lock plug. Other models are available, with Pigtail, 3 prong Edison Power Plug, and Stage Pin connectors. The Source Four Junior is also available with a 26, or a 50° lens tube.


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.
