Hi, I bought a pool light from your company in 2016. It is a normal white cover round with blue led.  
It has failed COMPLETly with about three or four led still burning. Now I know it is a few years old but you say your led will last twenty years if left on.
Mine did only 4 years burning every night. The unit is not damaged and has no water inside it.
Would there be some sort of warranty on the light still?
If not I want to open the unit and see if I can repair it.
Please let us know.
