I've noticed since our refinish that our lights were not as bright in our pool as the original build. I thought it was the black stones added to the finish that was cutting the light but when I looked closer at the light lens itself, the "W" on the lens is in the 12 o'clock position. Can anyone confirm that this means the lights are in the wide mode as opposed to narrow ("N")? Is it easy to change this and will I need new gaskets? The pool is less than 6 months old. Thanks for the help.
