Is this aquarium light waterproof? Please note: the cover is not sealed and chips lack glue protection. Avoid water splash or water vapor into led chips. We recommend using a transparent lid underneath or add aquarium riser for extra protection. Does it have a memory function for power outages? It retains the last mode after a power outage, but it doesn't have a real-time clock. Once power comes back, it resets the timer and starts counting from zero. I can't set the timer, and the light is very dim. What should I do? After programming, brightness ramps from 1% to your preset level over 15 mins, then fades down in final 15 mins. Pressing any button after setting cancels timer. Check timer indicator — lighting on means timer function is active. how to set up the day/night cycle? Press W/B button to adjust color & brightness. Set Day Timer for run hours, then Night Timer for night hours. Both timers will activate accordingly.
