A surface mounted fixture is on the surface of the pool and will typically involve unscrewing the screws or removing the clips that hold it in place. Once the cover is removed, you should have access to the bulb. A submersible fixture is located underwater and you may require a special pool light removal tool or specialized wrench to unscrew the fixture from its niche. Consult the manufacturer's instructions for specific details about accessing the fixture. 
  4. Carefully remove the old bulb from the fixture. It' it's a threaded bulb, twist counterclockwise to loosen and remove the bulb. It it's a push and turn type bulb, gently push it in and twist it counterclockwise to release it from the socket.

  7. Reattach the fixture's cover by securing the screws or clips. For submersible fixtures, carefully lower the fixture back into the nice, ensuring it aligns properly, and use the removal tool or wrench to tighten it securely.

Pool Light Bulbs Technical Information

Pool light bulbs are available in either 120 volt or 12 volt. There is no difference in brightness but 12 volts is a lower and safer level of electricity. In some municipalities it is required that lights be wired to operate on 12 volts for swimming pool use. If this is the case you will notice a transformer that converts the 120 volts you find in most household outlets and reduces it down to 12 volts. If you are replacing a light and are unsure of the voltage there are few ways you can determine this. If there is a transformer than you can be sure it operates on 12 volts.

It can be difficult to determine how much lighting you need for your pool but the good news is there are a lot of inground pool lighting options available. If you want lighting to create a fun pool atmosphere for children you may want a color changing light while a white light would work great for relaxing evenings.  Placement and the amount of light you use will change how the lighting looks. Consider adding more lights or choosing a color that compliments your pool liner.
