I fitted about 36 lumilife LEDs for a customer a few months ago and so far three have failed, I recomended them to a friend, before they failed, and he fitted about 40 of which over 4 have failed but they are no longer doing the ones he fitted and the replacements look completely different. Even with a good mark up there is no profit when you have made a few visits to replace faulty ones.
I have had no problems with a variety of manufacturers complete LED fittings but they are expensive.
I have fitted three external LED flood lamps, cheap to expensive, in the last year and so far two failed only the cheap one is still going. When I got the replacement of one of them to site and just about to screw it to the wall I noticed a casting crack in the case so I had to get it replaced again.
I am getting fed up with LEDs.
