I just moved into a new house. I have all LED lights, but 5 have blown in 4 months. They have a warranty of a year. I've also had the power board of my TV fail. I thought spikes and dips, but current is supposed to be stable in the Fish Hoek valley in Cape Town. General opinion is I don't need a voltage regulator/stabiliser. There aren't any shorts, all the trip switches are working and the earth leakage unit is working (tested last weekend). Could there still be an earth problem.
