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.

The heat comes from the LED, it doesn't get transferred to the LED.

Ah, is the heat mainly from the LEDs rather than the PSU?
