ok, so the previous owners of our IG pool decided that the light was of no use or not important enough to replace if it went bad....sooooo, we have a blue plastic disc that is covering the light "hole" Rust seeps from it as you may have seen in previous pics....we found the junction but I need your opinion on how high to go....ive seen lights from 175 to 800 ?!?!?!?!!!! We both do like a good time and love disco but we also have a budget that has to do everything the pool needs to be up and running, lol
