thats a bummer OP, at least they are standing behind it.

sounds like your power could be really dirty, the usual return rate on meanwells is super low

some good tips in this thread. killawatts are cheap and a good place to start

My watt meter jumping every couple moments (seconds) from let's say 220.1 W to 220.8 W.
Is this a potential trouble, if I understand right? It must be constant on watt meter?
I wouldn't think that small amount would be a problem, but you should ask an expert on that matter. Mine fluctuates too.

Fluctuating a fraction of a Watt is probably not a problem.

What are the Kill-O-Watt's accuracy/tolerance? (this is not exactly metrology equipment)

My guess is there is some issue with the load(intermittent?) or the driver has some further underlying problem.

Having multiple drivers on the same mains and only one keeps failing doesn't leave me to blame it on dirty mains, but anything is possible.

It has actually been both of my 240-1750B's this being the second time of one.
But as I mentioned before, nothing else including the other drivers in my Chinese EcoSunLite, that are much less quality than Meanwell, has failed at all. I guess I could get a kilowatt. They sell brand name ones at Harbor Freight.

The entire room is on a 20amp circuit.

So as some of you may know, I've recently ran the 240-2100 in place of the 1750 being RMA'd on 3 CXB3590's rather than 4. Its been running for about a week now no problems. All has been well. But today, I came to all 3 cobs VERY dimly lighting up just a handful of diodes. I initially thought the driver had done the same thing again! Nope. This is what I discovered.

Yes a nniiiiice n' crispy, bubbled out COB.
I have NO explanation for this. It's been just fine the last few days on this driver and once I re connected it all together with the other COB not in use, it fires right up. Nice and bright. I'm lost as can be. Any ideas? Not a thermal problem.

How hard are we’re you driving them? How much do you have on the one breaker? You may want to get your box checked if your not comfortable doing so. Very likely you have a loose ground or the screw that that hold the wire in the breaker will get loose over time especially if the wires are getting warm when running. If the wire is loose on that particular breaker check them all an replace that breaker it could have been getting bad voltage due to a bad connection.

I run through my box every 6 months or so and check the breakers and grounds to ensure they’re all tight. Energy is vibration so it’s good to check every so often.

Make sure all your wires are perfectly connected, soldered where you can.
Also, make sure push-in connectors are solidly locked in. My lights kept flickering for months until I finally replaced the last 2 inches of wire to one that sits better in the clips.

My breaker is well connected. I just pulled the panel off and checked. It's 20amp brake with 12-2 Romex. It has roughly 1400-1600watts on it depending on if the chiller is running or not. It should be just fine.
I wired the room up myself. I'm wondering if I did the outlet receptacles wrong perhaps? I don't think I did though. They all work great.

If all that’s good in the box and everything is tight I’d get a line or something that will clean the power coming from the plug.

They're all connected with solder besides the connections at the driver. Using spade connectors there because I had to switch out the drivers while being fixed.

Have you measured your mains voltage? Put it on a scope? Is it dirty? Does it fluctuate?

Do you have other electronics powered from the same mains (at that location?) Have any other appliances died in this manner seemingly from random events?

No this is most definitely a one off. Nothing has eveever happened.
