I replaced all of my light bulbs (CFL's) with Phillips 60W LEDs when they were on sale with coupons last October 2017. They claim they will last 13+ years if used 4hours / day for 7 days a week. 6 months later…. they are flickering in the lights (overhead ceiling fixtures/no dimmers). When I take a look, the bulb has separated where the metal socket and glass bulb meet -hanging off the insides of the bulb and the interior white coating is missing in spots.
Home Depot has given me my money back for some… but they cannot explain what is happening to them. Phillips is asking for receipts – which I do not have anymore. I am about to ramp up my discussion with Phillips – but wondered if anyone else has had similar issues?

Many LED lamps are designed to ONLY be used base down because the LED "driver" (the power supply board that is the equivalent of the ballast in a CFL lamp) must be able to dissipate the heat. It likely said so in small font on the packaging, but you didn't notice or didn't realize what that means. In some cases the mfr is less than forthright about that though, and a quick look at Phillips' site makes me think they are in that category. When used in things like overhead fans where the base is up AND the air cannot flow around it, the heat of the driver cannot escape to the surrounding air and the glue holding it all together separates.
