Failing LEDs Our workshops are, of course, lit with LED tubes, typically for about five hours a day. Unfortunately, I’ve noticed that longevity isn’t great. I had two failures of “Müller Licht” LED fixtures within a year, as well as one failure from “Osram”, and one from “Philips”. With the Müller Licht ones, one of the three LED strips failed first, then the remaining two got a bit brighter, and shortly afterward, it went completely dark. The Osram and Philips ones just stopped working abruptly. I also have an E27 LED lamp, it flickered at first and then stopped working. I opened it up, and the LEDs themselves are fine.
