The black ETC Source Four Junior 575 Watt 50 Degree Ellipsoidal Spotlight with three-prong Edison 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 theater venues, schools, industrials, and any other application where affordability, space-savings and high performance are the criteria.

When fitted with a 575W HPL bulb (available separately), this fixture will provide a beam of 220 foot candles 9.3' in diameter, from a distance of 10'. It will throw 55 foot candles 18.6' in diameter, from a distance of 20'.

This model includes a three-prong Edison power plug. Other models are available, with pigtail, stage pin, and twist-lock 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.
