Discontinued and replaced by the second-generation Source 4WRD II LED. Remaining stock available while supplies last.
The Source Four LED you've been waiting for has finally arrived! The Source 4WRD (Forward, aka Watt Reduction Device) is a drop-in replacement for your existing Source Four fixtures. With the brightness of a 575w long-life lamp and a 60,000 hour L70 lifetime, this fixture is the perfect solution for transitioning to the future of LED lighting.
No DMX at your fixture positions? No problem! The Source 4WRD can be dimmed via standard DMX or with most existing dimmers¹! Perfect for venues just starting the transition to LED fixtures, or those looking to save on relamping costs. The simple and quick upgrade is non-destructive and takes only minutes. In most cases it can even be done without breaking focus on your existing fixture. Best of all, because it is an LED source, your Source Four luminaires will run cool and efficiently without lamp replacements.

*RJ45 connectors are for DMX512 control only, this fixture will not work on lighting networks (sACN/Net3/etc.). They simply allow you to use cheaper Cat5e cable instead of 5-pin DMX.
¹ As with all mains-dimmable LEDs, the S4WRD works best with a small (~3%) preheat intensity, and may appear to be ghosting at low single-digit intensities. Using DMX control eliminates any ghosting. With multiple wireless DMX options you can easily expand your existing DMX infrastructure. ETC also maintains a listing of dimmer settings that yield the best results (will not match DMX control)
