ETC Source 4WRD System


4WRD progress starts here

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.

This incredible advancement to the Source Four fixture is available either as a retrofit or as a complete light engine. 120v model is available now; 230v model will be available in the near future.

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 using RJ45 connections 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.

We’ve taken the design from our classic Source Four PAR and PARNel fixtures and made them even better, keeping all of the same features you love with the added benefits of LEDs. If you thought the incandescent fixtures were bright, just wait until you see the Source 4WRD PAR and Source 4WRD PARNel in action!

We found 10,000 reasons to mess with a good thing

And those reasons are lumens - 10,000 lumens to be exact. That’s 20% more light than a Source Four PAR using a 750w long-life lamp.

Using the same Source 4WRD LED back end you would use on a Source Four incandescent fixture, these Source 4WRD PAR and Source 4WRD PARNel fixture bodies are a great addition to any venue that already has S4WRDs in inventory. Swap out the Source Four incandescent fixture body for a Source 4WRD PAR or PARNel fixture body, and you immediately have an incredibly flexible inventory of LEDs.

The best remains

Same accessories and smooth light. The new Source 4WRD PAR and Source 4WRD PARNel fixtures use the same rugged, die-cast aluminum construction as the original fixtures, and produce the same smooth, even field of light. The only change is that the 575W lamp has been swapped for a 155W LED source. This means, no more lamps to keep in inventory!

There’s no need to buy new accessories for your new Source 4WRD PAR and PARNel fixtures. All existing Source Four PAR lenses and accessories are compatible with the new design. The same set of four snap-in lenses you already have in inventory, work with these fixtures as well.
