ETC/Elec Theatre Controls S4WRDFB-C
Source 4WRD Light Engine with Barrel and Grounded 20A Twistlock Connector

OUR PART #  S4WRDFB-C


The ETC S4WRDFB is a combination of ETC's full-size, tungsten Source Four light fixture with the Source 4WRD Watt Reduction Device kit. The Source 4WRD replaces the standard Source Four burner assembly to convert the HPL source to a white-light LED, which provides a significant reduction in power consumption.  

With the Source 4WRD installed, this light is theatrically dimmable via DMX or line dimmable – with a traditional LED curve – to allow flexibility for your installation. Plus, since this light is an LED source, it will run cool and efficiently without the need for regular lamp replacements. This model comes terminated with a grounded 20A twistlock connector.
