The consensus on this question ranges from "using LED light bulbs in enclosures presents a fire risk" to "using LED light bulbs in enclosures presents NO fire risk, but shortens the life of the bulb due to overheating". LED lights get hot at the base, but they don't seem to get nearly as hot as incandescent bulbs. In an enclosure, heat does not vent out of the enclosure, and the heat source from bulbs builds up. Some commenters in these articles claim there isn't much of a problem with the bulbs if they are only used outside at night when it is cooler, or if they are only on for a short time — such as in a bathroom. But what if the light is left on for a long period because someone forgets to turn it off. To play it safe, find bulbs that are stated to be "suitable for enclosure" … otherwise users must be sure that regular LED bulbs are not used in enclosures where they might be turned on in enclosures for prolonged periods — especially in hot environments. In one article, there was discussion that heat damage is cumulative and causes damage to LED bulb circuitry. One symptom of damage might be dimming of the output of the bulb.

Mar 27, 2018 - This could be for many reasons, such as keeping water out or simply to protect the circuitry underneath. However, even with LEDs, the lighting is also a heat source and in enclosed fixtures the light has less space to spread out. When the heat doesn't spread out, it has to go somewhere, so it goes back in.
