How are you mounting this stuff? Are to ensuring you have adequate ventilation? Are you runnig fixtures all night that have duty cycles?
Do you have bad power? Weak power? Are you overloading breakers?
It makes a difference, although the LED one is confusing. My thoughts: your power sucks. Investigate that, measure the load under stress and see where it's at. Not to name brands, but get a good Furman power conditioner and unit that will show voltage and draw and put them where you can monitor it.
I'm not immune to problems. I had a stinky fog machine they swapped out under warranty. I had a motor on a fixture fail. I had a bulb break. But fail? No, not yet.
I don't want to point fingers until I have more information.
