WYZM
WYZM Color-Changing Pool Light Bulb (120V)
Best value — The value retrofit: a 120V color-changing LED bulb that screws into an existing E26 wet niche, on the deepest owner base in this post (3.8 stars across 809 owners) at about $42. The cheapest honest way to bring color back to a pool with an existing fixture — accepting that cheap RGB bulbs eventually lose a color channel.

Pros
- Deepest owner base in the post — 3.8 stars across 809 owners
- About $42 — the cheapest retrofit here
- Turns a failed niche fixture into color without replacing the whole light and housing
Cons
- Not for you if your system is 12V — this is 120V (grab the WYZM 12V version instead)
- The honest knock owners hit: individual color channels fade over time ('only red and green work now')
- No published warranty — it's a consumable bulb, so budget to replace it eventually
“My original LED light installed when the pool was built failed after two years. Because there was no bulb to change out, the entire light and housing had to be replaced.”— Denny C., Amazon · Verified owner
