ETC Source 4WRD II LED Retrofit Kit with Multiple Configurations

The ETC Source 4WRD II provides a direct, nondestructive replacement of the incandescent burner in a Source Four fixture, converting it into a high-performance white‑light LED. Ideal for retrofitting venues with theatrical lighting, it delivers significant energy savings while maintaining brightness and beam quality.

Available in professional-grade 3200 K (80 or 90+ CRI) and 5900 K (90+ CRI) color options, the unit supports both DMX dimming and line dimming. It offers easy lens tube interchangeability (5–90°) and runs cool, reducing lamp maintenance and heat load.
