Replacement Pool Lighting for American Products SN750 Fixture Housing

Greetings;

I purchased a neglected home with a more neglected pool and I am doing my best to repair and update the old pool systems, dating from approximately 1999.  My Pool Box was a disaster and the old lighting transformer was rusted and unrecognizable, and so I pulled the pool lights completely out to avoid any electrical hazards while I got everything else up and running (updated box, new pumps, wiring, etc.)  Now, I would now like to repair and replace my pool lights and have some questions.

My pool niche inserts (in very good condition) read:

-----    American Products, Moorpark, Ca.

Model SN750 Fixture Housing (Concrete)

Model SNL750 Fixture Housing (Prefab.)

For use with models S-100 & 12V100 Fixtures

The old lighting fixture did not have any nomenclature, but it was evidently the American Products Lighting fixture that came with the above prefab’d niche fixture, given that the glass lens had American Products markings on it.  The bulb was a GE EYC 75W 12V Hologen, the exterior trim ring is Stainless Steel, 5-3/4" diameter, and the glass lens cover is 5-3/4" in diameter.

1.  I would like to replace these older style lights and electronics with newer LED units.  Does anyone happen to know if there are there any direct replacement LED type units available for my SN750 Fixture Housings??

2.  If nothing is available I would appreciate any recommendations you all might have regarding my repairing my lighting system.

Thank you for your time and assistance.

Best regards – Bob
