Local factory possibly causing premature failure of LED lights in nearby house ?

aligarjon

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 .

    I have seen similar issues caused by adjacent premises.  A client of mine was having endless grief with LED lights, as well as expensive computer equipment, burning out (sometimes fairly dramatically).  He was noticing his lights always tended to flicker in the evenings, whenever his neighbour across the road would be using a welder.  I fitted an SPD almost a year ago for him and he has had no problems since.

    Another issue I once had was after fitting a large number of new LED lights to a building, only to find that they kept flickering when I turned them on (last thing on a Friday evening!).  After some investigation, it turned out that the voltage coming into the building was considerably lower than it should have been.  There was a restaurant next door, supplied by the same transformer, and it was in full operation at the time (with a lot of cooking appliances etc. running).  When I measured the voltage again the next morning, with the restaurant closed, it was well within specification.
