They put out much less heat, but they're also much more sensitive to heat. (Incandescent bulbs, meanwhile, are heat, and mostly don't mind.)

- dv_dt 6y agoThe leds are generally ok as components, but badly designed power electronics are the failing portion. However, strand LEDs designed for bulbs w/ no power electronics are on a completely different reliability basis.
- fennecfoxen 6y agoSometimes it's not even that; I've had bulbs where the glue holding the frosted glass part came off the base, because of the heat.
- pwg 6y agoCombine this fact with the fact that most enclosed fixtures that were designed for incandescent bulbs are insulated (at least on the mounting side) to keep the heat from the bulb inside the fixture (fire prevention reasons) and even the low heat level output by an LED bulb can eventually warm the interior above the temperature that the driver electronics can tolerate.
