A recent rewire saw the electrician fit LED bulbs throughout the house. Modern fire safe housings etc, plenty of ventilation.
These were not cheap off the shelf bulbs from the local store.
3 in the kitchen went after less than a year.
I contacted the manufacturer directly. Turns out they had a "bad batch". How many bulbs did I fit?
About 50..
A box of 48 bulbs turned up 2 days later.
Not a single other bulb has gone 4 years later.
Not sure what the lesson there is. You win some you lose some? It's not always down to cheap bulbs?
