No. Led is not replaceable. Should last 5 - 10,000 hours.

It is an LED the type of fixture that works off of Light Emitting Diode's ( LED) there is no bulb to change its a different technology. as far as how long it will last I think they claimed over 10,000 hours

There are a lot of led diodes in each light, so I imagine if one were to burn out there are plenty left. Not sure of the exact lifespan but Google suggests LEDs last 20,000-25,000 hours

I've had it for a few years now and they are just as bright as when they were new. I'm not sure if you can replace them but they are LED's and should last for years.
