I have a 15x30 ft gunite pool with an old fiber stars light that has gone belly up. I would like to replace it with an LED. My question is-- I don't have the model # for this light-- it's nowhere on the sticker attached to the unit and I really can't remember when I had it installed 10+ years ago. How can I tell which lights will be compatible with the current "niche" ? Also, what's the most cost effective LED out there that will light the pool? I'm not really interested in the color changing lights, although I have to admit they are really cool.
Thanks for the help.
