I am installing 2 Jandy watercolors led nicheless lights, JLU4C12W100, in hayward inlets SP1408. I thought the light gasket would seal against a lip in the inlet, but it does not even reach the lip. My distributer is saying it is fine for water to leak into the conduit and I just need to have the transformer above the water line. Has anyone had experience installing these? Should I seal the lights with silicone to stop them from leaking into the conduit?
