My pool light stopped working....

I figured it was the bulb. I got it out of my inground pool and put in a new bulb. It didn't work either. I used a non contact voltage tester to see if there was electricity going to the socket, but there was none.

The light is controlled by a light switch inside my house. I don't even know where to begin to try to resolve this.
 
Welcome to TFP.

There should be a GFCI in the light circuit. Check the GFCI is not tripped. The light may be wired through a GFCI outlet.

Post pictures of your equipment pad so we can see what you have.
 
Was there water inside the light?

In the picture above, inside that black box on top of the two PVC pipes, is your light connection. Turn the main breaker off and take out the screws to that black box. Then turn the breaker back on. At this point be very careful because there will be 120v at that connection, hopefully. Use a multimeter and it will tell you if there’s voltage to it. Make sure your wall switch is on when you check it. If there isn’t 120v, the failure will be before there. Maybe the breaker.

Let us know what you find.
 
Okay, I see there is electricity to the light switch. I did open the junction box and did not detect any electricity on any wires. I'm attaching photos of my equipment.

You have low voltage pool lights with a transformer.

Check the high voltage into the transformer and the low voltage 12V-14V out from the transformer.

With a low voltage light your non-contact test would not have sensed the voltage.

What model pool light do you have and what type of bulb did you put in it?

I'm sorry. Can you either describe or circle what I should try testing? If I don't already sound stupid, I'm about to. I'm not sure what kind of bulb it is. There is no writing on the old one, but I'm attaching a picture of that too. I tried a bulb exactly the same size and shape, but I also tried an LED light for pools that did not work.

I'm also including the sticker that is on the light fixture.

Your light looks like a 120V light yet you show it being connected through a pool light transformer. Something is confused.

Plus you cannot find any GFCI on the light circuit which makes the pool light UNSAFE to use.

You need to stop and bring in a handyman or electrician who understands pool light wiring.

If your light is a 120V light it should not be operated until it has GFCI protection.
 
Put in the correct bulb and use a multimeter to check voltages.

That really, really looks like a 120v floodlight bulb. I’m thinking the guy you talked to is confused. Did he see the pics you posted? Are there any markings on the bulb?

Also, I’m seeing corrosion on the bulb where the bulb screws into the fixture. That may be your problem if there’s corrosion inside the socket.
