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
The lifespan complaints are real but OLD — failures from five months to under three years, dated 2016-2020. The single 2026 card is the one to weigh: a repeat buyer who ran these happily for five years reordered and says what arrived is not the same product. Treat the 809-rating base as describing a bulb that may no longer be what ships.
