As the subject says. Is it possible that spikes of some sort from a local factory can cause premature failure of sensitive equipment.
Over the last few years i have regularly fitted a certain circular LED mains under cabinet light . Out of probably fitting well over a hundred, i know not a massive amount, i have never had a call back to replace any. I fitted 6 in a property local to me last year and have so far replaced 2 and just had a call back as another has failed. So dodgy batch possibly or is it possible that a local factory could be spiking the mains somehow ( literally next door but one to the house) ? I have replaced a couple of external LED lights at the same house. The factory is a wool mill or something similar making tennis balls and snooker table clothes amongst other things and runs all day and all night.
Any thoughts please, is that feasible ? I don't currently know if the latest failure is an original or a replacement .
