ETC Source Four Tungsten LED Light Engine without Lens Tube (Black) 

The Source Four LED line is the result of the marriage of the Source Four and Desire product lines yielding the control of a Source Four with color control of the Desire fixture. This ETC Source Four Tungsten LED Light Engine without Lens Tube (Black) - 100-240VAC is comprised of the light engine and shutter barrel. It is not a complete fixture, requiring a lens barrel for use. The light engine/shutter barrel is compatible with all ETC Source Four interchangeable lens tubes (see features and specs). For optimal results the updated LED 50° tube is suggested.


Among the many benefits of the light engine are multiple control options via DMX, superior color rendition, multi-voltage operation and long (50,000 hour) lamp life.
