One of my Meanwell ELN-60-27P failed. I think it overheated. It looks like there is a small amount of current running to the LEDs, but the driver is fried. I ordered another power supplly (200w, 24v, 8.3A) to power all three banks of LEDs together. I gave up on the idea of dimmig the LEDs. I will adjust the height of the LEDs if I have to change the light intensity. At least for now, that is what I'm doing. Here is a shot of the LEDs with one of the banks lit very dimly.
