I'm looking to upgrade my old Fiberstars illuminator with 4 fiber optic pool lights that was installed in 1993. I like the idea of the new Fiberstars PAL Treo LED lights with PT-6000 Power Tower retrofit system so I can use the existing 1-1/2 inch conduit and pool wall fittings for the lights. This looks like it should be a fairly easy DIY project since I have easy access to the four conduits and light box. The only issue is how best to get the old fiber optic lens out of the wall housing. They supposedly screw into the wall housing but since I haven't drained the pool yet I don't have any knowledge of just how to go about removing the old lenses. I'm assuming it requires a special tool, Fiberstars part number FS-117, sold as their lens tightening tool?
Does anyone have some advise on how these older fiber optic lights come out? Can this be a DIY project? I can buy all of the Fiberstars TREO LED lights and control box from online suppliers for about $1k less than having a pool contractor install them. I'd rather put that money towards a new pebble finish if I can do this lighting upgrade myself.
