Source 4WRD 

Source 4WRD (Watt Reduction Device) LED is a replacement for a standard Source Four® burner assembly that will convert the HPL source to a white-light LED and provides a significant reduction in power consumption. The simple and quick upgrade is nondestructive and takes less than a minute. In most cases it can even be done without breaking the fixture’s focus. Source 4WRD LED is theatrically dimmable via DMX or line dimmable, with a traditional LED curve, to allow flexibility for your installation. And, because it is an LED source, your fixtures will run cool and efficiently without lamp replacements.

Source 4WRD LED is capable of being both DMX or line-dimmed by a conventional SCR dimmer. In AC dimming mode, performance can vary based on the dimmer used 

and its control settings.  For this reason, AC dimming is best suited for level setting or traditional LED quality dimming situations.  When high-performance dimming is required, DMX mode should be used.  We recommend testing Source 4WRD LED on existing dimmers you may wish to use
