The ETC ColorSource Spot is an LED ellipsoidal fixture designed for theatrical and event lighting, offering rich color output through a four-color mixing system that includes red, green, blue, and lime emitters. This configuration enhances both brightness and color rendering, producing vibrant hues and smooth pastels with improved consistency across fixtures. The unit supports standard ETC lens tubes and accessories, making it adaptable for various beam angles and projection needs. It features a simple onboard interface with customizable presets, DMX and RDM control, and power linking for up to nine fixtures on a single circuit. Built with thermal management algorithms and factory calibration, the ColorSource Spot maintains color integrity over time and is rated for a long operational life of up to 54,000 hours under LM-84 testing standards.
