Had a customer that had some of his LEDs out on his ocean revive lights. He noticed his fans weren’t working. I checked mine here and I found two lights where one or two of the fans weren’t working. My LEDs are OK but I would imagine at some point the LEDs would burn out from excessive heat. So may want to check your fans, not just ocean revive but any led fixture to be sure they are working ok. It is a cheap fix (few dollars) if just replacing fan but much more pricey if Leds go.
