Product Description

Please Note: This is version one of the source 4wrd, for POA Pricing on V2 Please see Sales WL.

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 raditional 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.


  • Advance any full-size, tungsten Source Four ellipsoidal to LED efficiency in seconds, and without special tools.
  • Same optics, same accessories, same flexibility as a Source Four fixture.
  • As bright as a 575-watt, extended life HPL lamp.
  • 70% less power, no re-lamping, no-hassle swap out.

Source 4WRD is available in three array variants:

  • 3000K 80CRI or 90CRI (Gallery) - perfect for any venue looking for a warm white light. Available as a full 230V fixture or a retrofit for existing 230V Source Four fixtures.
  • 5600K 90CRI (Daylight Gallery) - ideal for television studios, industrial trade shows, and other live events, this array provides the coolest, and brightest white light in an LED fixture. Works with existing Source Four, Source 4WRD PAR, and Source 4WRD PARNel fixtures.
