ETC Source 4WRD Color II is an LED retrofit engine designed to convert traditional Source Four incandescent fixtures into full-color RGB LED units. Delivering high output, improved color mixing, and reduced power consumption, it allows users to upgrade existing lighting systems quickly while maintaining the familiar optics and performance of the original fixture.
The ETC Source 4WRD Color II offers a practical solution for upgrading legacy lighting systems to modern LED performance without replacing entire fixtures. Designed specifically for compatibility with ETC Source Four units, this retrofit engine installs in minutes and retains the optical quality and beam shaping that made the original fixture a standard in theaters, houses of worship, and performance spaces.
Its advanced RGB LED array produces vibrant colors and a wide range of white light from warm to cool tones. With improved brightness and enhanced red output, the fixture delivers better color rendering and more saturated hues, making it suitable for stage lighting, architectural applications, and event environments that demand versatility.
Control options include DMX via dual RJ45 ports as well as onboard operation with 12 built-in color presets and 5 preset sequences. This allows for flexible use in both simple setups and fully programmed lighting systems. The unit requires a non-dimmable power source and features fan cooling for consistent performance during extended operation.
ETC Source 4WRD Color II is also designed for long-term efficiency, offering reduced energy consumption and a rated LED life of up to 60,000 hours. Its durable cast aluminum construction and compact design make it a reliable upgrade solution for theaters, schools, hospitality venues, retail spaces, and touring productions.
