I place a small square of furnace filter material on the fan intakes on the top. That reduces dirt and some moisture that can get drawn into the fixture. There isn't much to short out in them, the drivers just die in a small percentage of them. This is the downside to Chinese hardware, it's cheap, it works, but it isn't very well made inside. But at a third of the price of other fixtures, it's a gamble worth taking IMO
. But I'm following my sons lead from now on and using group buy LED
purchases to build my own fixtures. I am comfortable with electronics and it is the way to get exactly what you want for the lowest price possible.
