The super bright light I bought from Home Depot for my garage has 4 arms full of LEDs. But it screws into a standard socket, so when I need to replace it (long before its time I'm sure) I'll just unscrew it and screw in a new one.

I had an over-the-stove microwave with an overhead light. When the bulb burned out I replaced it with a LED. The new bulb outlasted the microwave.
