Thermistors will help, yes, but the manufacturers need to design better enclosures for LED lightbulbs. They need fair air circulation for that heat sink to work well. And in recessed lighting it's the worst. It's a design issue of the bulb, sure, but especially the fixture. LEDs aren't friendly to high heat like incandescents are, and most light fixtures have been designed with complete disregard to the heat of the fixture—so long as it won't start a fire. |

The CFL has a huge volume and a huge radiating area for the heat, and that area is well-connected thermally with the environment. Plus, it can operate at higher temperatures anyway.
The LED active element is a tiny chip of semiconductor material. All that heat is dumped in a tiny volume, and you can only put a heat sink on its back. Plus, the heat sink is close to the fixture and therefore necessarily hampered in its function.
It's not an easy problem to solve. If we think pie-in-the-sky solutions, perhaps a re-design of the connectors and fixtures might help - if you made a connector that was designed to take heat away from the bulb, that would help a lot; the whole fixture would become the heat sink.
