The ETC Source 4WRD Leko is a retrofitted solution: a transformed Source Four incandescent fixture. This light has been made into an energy-efficient LED unit without altering its optical performance or accessory compatibility. Designed for quick, tool-free installation, the Source 4WRD replaces the traditional HPL lamp assembly with a high-output LED engine, offering up to 11,430 lumens and a rated lifespan of over 45,000 hours. The Source 4WRD supports both DMX and line dimming, making it adaptable to legacy control systems. The fixture maintains the Source Four’s signature beam quality and lens tube compatibility, while reducing power consumption by up to 70% and minimizing heat output, which helps preserve gels and reduces maintenance needs.
