In LED lighting space, insufficient heat dissipation is commonly used for planned obsolescence. LED lifetime directly depends on temperature, and most light sources are way too powerful for their heat dissipation capabilities.
There are in fact LED bulbs that aren't overdriven to a deliberate and premature thermal death, but you can only buy them in Dubai: https://youtu.be/klaJqofCsu4
Lightbulbs have a long and very successful history of artificially driving lightbulb lifetimes down though a cartel system: https://youtu.be/j5v8D-alAKE
If you're building your own LED fixtures, you can probably underdrive the LEDs and run them at a radically cooler and slightly more efficient operating point, at a higher upfront cost: you need more LEDs for the same output.
