We plan to install either 12 or 24 volt LED strips (from W.A.C. Lighting) on a 4x10 ceiling beam in our bathroom. The plan is to locate the power supply in the lavatory sink base and run low voltage wire from the cabinet through the wall and into suitable box near the beam (about 5' away). Instead of running bare wire in the wall, we would like to use flexible PVC conduit. Is this ok or is there a better way to do it?
