I last changed the pool light bulb 3 yrs ago. Now that I have the pool drained and cleaned, I decided to replace the pool light with a new color wheel unit (SAm).

It was pretty straight forward swap.
• Made sure the pool light switch was set to the off position and turned off the circuit breaker to the pool light.
• Solid conduit going from the niche to the GFI outlet near the diving board.
• I just undid the two wires on the GFI outlet and untwisted the wire nut for the light's ground wire.
• Pulled the old pool light wire through the conduit from the niche end.
• Fiched up the new pool light wire through the conduit and wired the new light to the GFI outlet.

My layout was a near exact match to this diagram:

Picture is from the Owners manual for the Pentair Spectrum Amerlite SAm light.

My light ring's finish was pretty worn out, chrome finish worn through. The heavy & thick metal ring was showing the copper base metal (or rust?).

I tried getting a replacement light ring at the pool store, but my light ring was an old discontinued line (Aladdin ~30 yrs old). A replacement light ring adapter was going to be $$ and would have to be special ordered.

I decided to have it refinished, it would be a less expensive route. Re-chroming would take some time, so I had it powder coated with a chrome like finish and then clear coated to resist the pool chemicals. Cost me $40 and a two day turn around.
