When your pool or spa light fails and you need to replace the bulb, the first question you have to answer is what kind of light do you have. You will need to know the manufacture name, model #, voltage and wattage of your light. This information is generally on a label on the backside of the light fixture. This guide shows you how to get to that information.

Tips & Warnings

Step by Step

Step 1

To avoid possible electric shock, turn off the power to the pool light at the circuit breaker.

Step 2

Most pool light fixtures are secured to the niche in the pool wall with a single screw at the top of the light. Remove this screw. If the pool light is just below the surface, you may be able to remove the screw by leaning over the pool deck. In this case I had to get in the pool and hold my breath to remove the screw. Wear goggles.

Step 3

Pull the pool light fixture out of the niche. You should have enough excess cord to be able to lay the light fixture on the pool deck. Note how the excess cord is stored in the niche so you can replace it the same way when you reinstall the pool light.

Step 4

Lay the light fixture gently on the pool deck.

Step 5

Look for any information that may be on the lens of the pool light. In this case the manufacturer's name, American Products Company, can be seen on the lens.

Step 6

Look on the backside of the pool light fixture for an identification label.

Step 7

This label was in the water 12 years and a little hard to read but we were still able to read the information we needed: model # H-400-BCL, watts 400 and volts 120. Using this data we identified the light as a Pentair Amerlite 400w 120V. Note - Pentair bought American Products.

Step 8

Replace the light fixture by first recoiling and storing the excess cable as observed in step 3. Then push the light fixture back into the niche.

Step 9

Replaced the single screw to secure the pool light fixture to the niche

Step 10

Restore power to the swimming pool light fixture.

Short light cord - Sounds like a good approach. Tie a strong cord or fish tape to the light cable at the house connection end; pull out an extra 10' or 15' of cable on the pool end to get the light onto the deck; then pull the 10' to 15' back when you are done to reconnect it to the house box.

I have a pool light on the deep end burned out but when I removed the light from the niche, I find there is not sufficient cable to raise the fixture to the pool deck in order to work on it. Not sure if I can tie onto cable and pull it through and back or if I should replace the entire light fixture, and if so, would the water have to be drained to below the light?

No power to light - Take the light fixture apart again and check the power at the light lead to make sure you have power to the light.

I took the fixture out and when I started to unscrew the bulb it broke . thats when I noticed this little spring. The spring is broken. All of the fixtures have this spring. Why and what purpose does it serve?

Jack - I can't tell you exactly with more information, but..Many of the lights installed at that time were American Products, like the one in this. Go to this link and see if the parts look like yours. Also when you select a light or gasket from the list of parts, it will provide some dimensions to check against. Link is http://www.inyopools.com/pool_parts_pentair_amerlite_pool_light.aspx. Note see bottom of product page. This light used to be sold under American Products.

I have removed the pool light, but I don't see any identifying information on the lense and the label on the light itself is not ledgible. I was told that the pool is a Anthony pool (probably from 80's). My light fixture looks very similar to the one in the photo...I don't want to order the wrong replacement light fixutre. Any suggestions?
