Hi guys, just a quick update. I received the LED drivers and just spent an hour or so playing with them. Everything worked like a charm so tomorrow they go into Shackleton. I was particularly pleased because running them in air for a minute or so, both the lights and drives were still cool to the touch. I was running two 5K lights off a shared drive, which I set at 34.1V and 2.34A per the LED specs. That's 80 watts, and this is a 400 watt drive so I guess that's how one ends up with cool circuitry. This is not going to need a fan on its enclosure, just holes. My drive is a "MingHe D3806."<br>
<br>
The drives came with no instructions whatsoever but there were reasonable explanations online. Here is a video that will give you a pretty clear idea of how they are configured. The video is of another model from the same manufacturer, but the controls are identical. Mine is a combination step up / step down, which has the benefit of more input voltage flexibility but is less efficient.<br>
