Success!! Jumped in the pool, wrapped the wire around a piece of PVC pipe, put my feet on pool side and was able to pull the power wire intact. Tried to get a fish through from the breaker box, but it got stuck abt 65 feet into the conduit. Pulled the fish back out and connected the ground wire to the fish. Was able to pull the ground wire out into the pool along with the fish. Connected the new pool light to the fish along with the ground wire and pulled them both back thru the conduit without too much trouble. I did give the wires a good silicon grease treatment, which I'm sure helped.

Currently enjoying the color LED light show. Life is good....
