Usually all you need is the replacement bulb in LED but I have no idea what the bulb is like so maybe post a pic of that and also where the lights are now.

How about contacting a local pool installer? They may know.

Thank you! All the pool installers are super busy, tried a couple and no response. Wanted to do my homework. I dont have pictures, it's inside the pool. We have replaced bulbs before but the keep going out, one of the lights stopped rotating and now 3 of them dont work. The bulbs are hard to find so I thought an upgrade may be better.

If you have replaced the bulbs previously can you show us what the bulb looks like? If the bulbs are starting to rotate in the fixture it may be time to replace the fixture...

We replaced it last summer....our local Leslies did not have the bulb, so had to go to one 50 miles away. I think all the fixtures need to be replaced and I would like to use the LED fixtures instead of replacing with the same. Wanted to see what it entails.

If the bulbs are replacable, then it's very likely that you can buy a LED version of it. for example, you can get led "halogen" bulbs to replace bulbs in track lighting. they're not technically halogen, and they might look a different at the top, but the base is the same.

But we don't know what kind of bulbs you used before. Your best approach is to take one bulb from your pool and bring it to a lighting store. Don't go to Lowes or Home Depot, their selection of specialty bulbs is terrible.

Also, don't cheap out on LEDs. they can last many years. but cheapo ones can fail in a year or less.

In addition to the bulbs, one of the lights is stuck, the color wheel doesn't rotate. I would like to replace the entire fixture to the new LED ones...

this is not really the greatest board for technical information. you might need to wait for a pool company to become available. sorry you have to wait, but at least your pool isn't broken or hazardous.
