Heat is the real killer for LEDs. Most LEDs sold for home lighting do not have very good thermal regulation, possibly as a planned obsolesence "feature".

- pkolaczk 2y agoYes, even expensive Phillips LEDs heat up to 100 C. There is no way they could last the designed 50000h at that temp.
- eru 2y agoPlanned obsolescence only makes business sense, if you can be reasonably sure that the customer will buy from you again. The home LED market is pretty fractured and there's not all that much brand loyalty. (At least at the lower level where companies churn out lowest cost LEDs. The companies that bet on brand loyalty tend to have somewhat better quality.)
