I have just started the process of our pool renovation and among other things, want to add a surface mount light. It appears the old niche type lights are a thing of the past anyway, but is there anything I should know about what seems like a pretty easy task?
From what I have worked out, I can core/drill a 25-30mm hole vertically in the pool wall, about 500-600mm down, then core or drill horizontally from the face of the wall to meet the vertical hole and there is the conduit line for the wire (12v), I'll then feed the wire down and out the wall face by a metre or so and then urethane seal the wires into the drilled hole, and epoxy the last 10mm or so flush with the pool wall face. This gives me watertight wiring. I'll then attach the mounting plate to the wall, wire the light and coil the excess in the back, and fit it to the mounting plate. On top, I will chase out a channel for a 20mm PVC conduit to run to go back to the transformer and I should be done.
So what I need to know is, is there a standard or accepted depth the light should be fitted below the waterline? I figured about 400mm (16") seems about right but I don't know. Also, where is the best place to position one?
The pool is this shape (having just removed the pavers that were laid on top of this concrete):
I though on the back wall next to the ladder, otherwise on the right hand side straight part, about 1/2 way along.
Ideas? Anyone done this and have tips? Cheers and thanks for reading!
