Color Changers

Color changers are lighting accessories used by lighting technicians in concerts, theaters and film studios, to remotely adapt the color of the light beam that their stage lighting equipment projects. There are two types of color changers in use today. Traditional color changers are called color scrollers, which are a type of mechanical equipment that positions plastic gels in front of the light beam. The light travels through the gel and thus the color of the light beam is changed. These color changers are fitted to the end of the light fixture, and so they do not actually affect the way the light beam is produced. More popular these days is the LED color changer, which employs an RDM protocol and uses smaller LED screens to change the color of the light beam. The LED color changer is proving to be popular, as it is considered easier to use and can provide more information to the lighting operator (it can provide diagnostic information). LED color changers offer a lot more versatility as well, as they include features such as a light sensor, voltage sensor, temperature sensor, gel string sensor, fan control, and self-testing abilities. Color changers come in three forms: Single string scrollers, dual string scrollers and CYM color mixing scrollers. Single string color changers are the most common type, but they only have one string of colors. Dual string color changers have two strings of color, while the CYM scrollers (called “true color changers”) operate with three color strings.
