hayward sp-540

I have a hayward sp-540 fixture the tag says to use with housing # 506,507 & 505 it says its 12 volt but is that ac or dc?

I would love to go with An LED i just dont know where to start cant find anything to cross refrence with it. do you know of anything that would fit even if slight modification would be no probs. thanx in advance…        Bob

Hello Bob - The voltage for pool lights is AC. The Hayward Universal Colorlogic light will fit in your existing niche.
