<div>Stuart,</div>
<div>After a long but fun and interesting Google search, I see what you mean, not many/any RGBI LED drivers. </div>
<div><br>
</div>
<div>I did maybe find one, the ADJ <span style="background-color: rgba(255, 255, 255, 0); font-size: medium;">
LED Pixel 4C, (or </span><span style="background-color: rgba(255, 255, 255, 0); font-size: medium;">LED Pixel 10C), manual at </span></div>
<div><a href="http://intranet.americandj.com/ItemRelatedFiles/6994/led-pixel-4c.pdf">http://intranet.americandj.com/ItemRelatedFiles/6994/led-pixel-4c.pdf</a>. </div>
<div>The controllers have a 5 channel mode, where DMX channels 1-3 are RGB, and DMX channel 4 is Intensity. DMX channel 5 effects strobe/sound activation. It's output controls 4 (or 10 for the 10c) led pixel tubes via 4 wires, at 24v; my guess is that there
is a wire for R, G, B, and ground. So if your existing DMX channels are not sequential, and you didn't drive the 5th DMX channel, and you could run on 24v, it might work... </div>
<div>And at $120, it might be worthwhile buying one to see, or tearing it apart to make it work. </div>
<div>There was also a Arduino DMX project that alluded to RGBI DMX controller. <a href="http://kll.engineering-news.org/kllfusion01/articles.php?article_id=7">http://kll.engineering-news.org/kllfusion01/articles.php?article_id=7</a>. You might be able to build
your own using the info there. </div>
<div><br>
</div>
<div>Interesting challenge. :-)</div>
<div>Best of luck!</div>

<div>I appear to have unintentionally led everyone astray. Let me try again.</div>
<div><br>
</div>
<div>We have a few shows using LEDion panels (flat LED panels common in discos etc) the panels have simple RGB LED strips inside, but they run from a driver module that is no longer supported by the manufacturer. That module uses 4 channels per panel. RGBI.
Modules could run 4,8, or 16 panels each from a DMX feed.</div>
<div><br>
</div>
<div>We used to be able to obtain the decoder chip in the driver box. But we can no longer get it.</div>
<div>Now when a driver fails, it is a brick... the show, however, must go on. We could Re wire the system to use a cluster of small LED dimmer blocks, but the existing cues are built around the RGBI drivers and most LED dimmers are not built that way, if
we cannot find a dimmer/driver that uses RGBI output, we will need to get the lighting for the show re-cued, adding considerable expense to a retrofit that will already cost serious dollars.</div>
<div><br>
</div>
<div>So what I am essentially looking for would be a small LED dimmer that has RGBI capability.</div>
<div><br>
</div>
<div>I apologize for the confusion.</div>
