I am in the process of renovating a 50' x 27' concrete pool and need to replace the light fixture. The fixture itself was removed years ago and the conduit capped off. The niche is a Hayward SP555 to use with light model #SP540, 541, 542 or 543. My research turned up this up to be the Starlite model which is no longer available with the Duralite Series as a replacement. My questions are as follows:
1. Is there a direct Duralite model replacement for the information I provided or can you recommend a product to use?
2. For a 50' rectangular pool, what wattage/voltage should be purchased? Light will project 50' from deep to shallow end of pool.
3. Can the replacement light fixture be used in a saltwater application? All descriptions seem to note "fresh water" use.
Thank you for your input!
