But it is true the problem with LED lightbulbs is that they do get very hot at the base as that's where the SMPS are but the heat can be transfered to the actual LEDs which don;t like being hot.
The life of the lamps might well be UP TO 15K hours but they are very liklely to fail long before that due to temperature as the 15K hours refers to an LED used within the specs and even then it doesn't mean it will last 15,000 hours.



Not all LED lamps have much in the way of PSUs

Basically a bridge and 3 passives.

They canlt easily be dimmed, they are crap, they flicker and don't last anywhere near as long as stated.
