Can you use any transformer for a pool light?

You absolutely need a "pool code" transformer (one that is rated for pool use) and I think code in most areas requires that it be hooked up through a GFCI circuit (either as part of the line side of a receptacle OR with it's own GFCI breaker) even though a GFCI breaker will not necessarily trip if there's a ground ...

Does a pool light need a dedicated circuit?

The light always has to be a dedicated circuit because it has to be protected by a Ground Fault Circuit Interrupter (GFCI). A GFCI is a device that monitors the amount of current flowing from hot to neutral. If there is an imbalance, it trips the circuit.

Are all pool lights 12V?

Why does my pool light keep tripping the GFCI?

This can be due to a small amount of water being inside your light fixture which the light may heat up and vaporize. This can then cause the GFCI to trip. GFCIs are also known to trip from extreme humidity. Be sure that the outlets that may be on the same GFCI circuit are covered to help prevent this.

Why don't my pool lights work?

Check the circuit breaker panel that's usually found on the side of your house. If the breaker that your pool light is on has been tripped, unplug whatever you just turned on or plugged in and then reset the breaker by turning it all the way off and then back on again. If that doesn't work, you may have a bad breaker.

How can I tell if I have a 12V or 120V pool light?

Look at the cord that is attached to the fixture. Weather it be at the junction box where it ties into the supply voltage, or if you take the fixture out of the niche and pull it up to the deck. The cord is black for 120v and bright orange for 12V.
