New pool owner here. I want to swap out my existing in ground pool light with a color changing LED one. Currently my existing light is a 500w and the new LED is only a 45w, will this require that the breaker at the electrical panel be downsized or should I leave it as is?
Thank.

The breaker goes by amps not watts so you are fine. It's probably a 15 or 20 amp breaker now. If it's a dedicated breaker you will have extra amps. On mine I tapped my light breaker for some outdoor plugs since the light is rarely used.
Also it should be GCFI breaker. If not, put one in.

Keep in mind that the breaker is there to see to it that the wire does not get overloaded and cause a fire. Because of that, breaker size should be matched to wire gauge (in the most common cases - as with anything, there are exceptions.

Generally speaking, a 20-amp breaker should host 12AWG wire, while a 15-amp breaker typically hosts 14AWG.

GFCI protection is to make sure you don’t touch something and become the best path to ground (at least for long).
