I have a customer that would like me to mount some PAR 30 floodlamps in his trees for a horseshoe pit. I have seen this done a number of times, however, I am not sure of the best and most reliable way to do it.

Power is coming up from the ground as 1/2" PVC. I would like to transition to RGC and go up the tree to a WP box, and mount the lights to that. However...how does a tree growing/blowing in the wind affect this??? Where does a tree gain its height?? If it is from the bottom, I think that my plan won't work! Anybody have any ideas on how to aproach this?
