Just for reference higher end bulbs like diode dynamics have a much higher spec for the max temp range (150 C or 302 F). From their site:
Reliability. From the high-temperature teflon wire, to the zinc castings, every part of the the SL1 was designed for reliability. The driver uses a unique boost-mode circuit, which prevents thermal imbalance in the LEDs, and has transient protection for long life in automotive circuits.
Finally, the SL1 bulb was put through its paces in our environmental testing chambers, through dozens of thermal cycles, from -40 to 150 degrees Celsius. The SL1 is a durable, reliable bulb, and is backed by a three year warranty.
