LED Driver Failed

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.

Well, the other power supply finally showed up. I installed the new power supply and that showed that instead of the Meanwell driver having failed, it was one of the LEDs that failed. The Meanwell driver is working fine. I replaced the bad LED (which was easy to find), and the string now works. Since the Meanwell drivers are all working, I am not using the single power supply, which didn't actually work that well anyhow.

Arghh... can you send the power supply back? Do you think the dimming might have shortened the life of that LED?

Yeah ... it was from China. Fortunately it was only $30. I guess you get what you pay for. I probably can use the power supply for something one day (I hope). As for the dimming, I wasn't using dimming, so I don't think it had anything to do with it. But I do wonder what caused the LED to fail.

Hi fizzout, i know this is an old thread but do you have any updates of your build with the typhoon controller? I'm about to make a similar setup as yours and am wondering, are you able to dim your Meanwell ELN-60-27p completely?

any pics of how the lights look over the tank. i am interested in the color rendition of plants and fish with so much cool white led. there seems to be a movement away from the cree cool whites even in some reefer forums due to poor color rendition making things looks washed out. over my vivs i prefer the color of 2 to1 warm cool to the other way around. and i prefer the color of my 4k bridgelux to either of those combos. my new tank will have 4 k bridgelux with a bunch of lower wattage leds added for flexability in color and adder pop. also i love the aluminum 80/20. i used it on my viv led build and found it very easy to work with.
