We’ve had very few go bad in the past few years. Most of the ones that did go bad were LEDs that weren’t meant for enclosed fixtures but were in enclosed fixtures.
I saw some for really cheap at an out of town Home Depot that looked too good to be true. I asked an associate if it was a mistake and he said that the local utility company was subsidizing them as their infrastructure was being overused and they wanted to encourage everyone to switch to LEDs which use much less electricity.
