We're about to start our pool project and are trying to light a raised beam water feature that sits on the edge of the pool. After much research, and wonderful help from this forum, we've narrowed down our lighting options to essentially placing a light towards the back of the seating surface of a submerged bench that sits just under the waterfall. But, despite finding a light the officially describes such an installation in their manual (Jandy nicheless LED), our PB is hesitant to mount any light vertically like this (they've never done it). Can someone enlighten me as to any concerns one might have with such light installation?
