The ETC S4WRDT120-B is a Source Four white-light LED retrofit designed for facilities and production teams that want to modernize existing fixtures without replacing the full luminaire. By replacing the standard burner assembly, it converts an HPL-based Source Four into an LED fixture while supporting a fast, nondestructive upgrade path. In many installations, the change can be completed in less than a minute and often without disturbing fixture focus, making it practical for active theatres, worship spaces, schools, hospitality venues, and meeting environments.

This retrofit is well suited to energy-saving projects where maintaining an established Source Four inventory matters. It supports theatrical dimming via DMX or line dimming with a traditional LED curve, giving integrators and lighting teams flexibility across permanent installations and performance spaces. As an LED source, it also helps reduce ongoing maintenance demands associated with lamp-based operation.

For venues seeking a more efficient white-light solution from existing Source Four fixtures, the S4WRDT120-B offers a straightforward path to cooler-running operation and lower power consumption while preserving the familiar fixture platform already in service.
