Somwething seems wrong if your non-cheap LEDs are dying that quickly. I have an entire house of LEDs, many going on 5-6 years old, and I only ever recall replacing two (and they were a pair, used outdoors -- only one failed, but I replaced both so they would match).
If you have 5-6 year old LED bulbs, then they represent the state of the market 5-6 years ago, and aren't necessarily representative of current quality.
