How to Replace Pool Light like a Pro

Many people swim in their pool in the daytime, and swimming at night is getting even more popular. Everyone loves showing friends how great their pool is…some share their nighttime swim images on social media with the hashtag #Nightswim.

Whether you enjoy a private midnight dip or love showing your Facebook friends how your pool looks after dark, there will come a time when you’ll have to change your pool light. For many pool owners, how to replace pool light fixtures may seem hard, with concerns about electricity or water exposure. It’s actually pretty simple with tips and tools we’ll share which can make replacing a pool light a manageable DIY project.

Swimming Pool Lights: Tips for Durability and Placement

Swimming pool lights vary in type, and include fixtures for in-ground and swimming pool lights for above ground pools. While in-ground pool lights are typically sealed within a niche in the pool wall, above-ground pool lights may be mounted differently, often providing simpler access.

LED swimming pool underwater lights are becoming popular for their energy efficiency and durability. Compared to other lights, LEDs can last up to 50,000 hours. That longevity will mean way fewer pool light changes over the years!

It’s important to light around the pool area, too. Speaking of LED lights, in addition to updating your pool light, you’ll want some directional lights for around the pool to increase safety and set up a beautiful evening glow. Best Pro Lighting provides a full selection of LED directional lights that can deliver the illumination you want, while providing the utmost in energy efficiency. Our Modern Bullet—BPL103 Low Voltage Landscape Lights and Low Voltage Landscape Directional Fiberglass Bullet in Bronze are two great choices that let you point the beam where you want, and provide long-lasting light. The fixtures are durable and will look great for years.

With all this in mind, your next move is to replace your pool light and place your LED directional lights around the pool area.

Signs Your Pool Light Needs Replacement

Common indicators that a pool light bulb should be replaced:

  • The bulb no longer illuminates, even after checking the power source.
  • Flickering bulbs will likely soon fail.
  • Discoloration of the light is a sign of a failing bulb or lens. 
  • Water inside the light fixture, visible as condensation or pooling, indicates a compromised seal, which can damage the bulb. 
  • Cracks in the lens or housing also require immediate attention. 

If any of these problems occur, it’s time to learn how to replace a pool light bulb. While it’s easy, there are a few safety tips and steps to follow.

Safety First: What to Know Before You Start

Turn off the power to the pool light at the circuit breaker and use a voltage tester to ensure it’s off. You may need to drain the pool to below the light fixture, though many modern fixtures allow bulb replacement without draining. You should wear rubber-soled shoes and gloves to protect yourself in case of electric shock.

Choosing the Right Replacement Bulb

This part is easy; you’ll find information in your pool light manual, or look at the existing bulb for specifications. Check the voltage (typically 12V or 120V), wattage, and bulb type (LED, halogen). For most pools, a best watt recommended for pool light ranges from 300 to 500 watts for halogen bulbs or 15 to 40 watts for LED equivalents.

Ensure the replacement bulb is compatible with your fixture’s niche and sealing system to prevent leaks. If switching to LED, verify the color temperature (warm white or cool white) matches your preference.

Step-by-Step Replacement Process

You’ll need to remove the single screw at the top of the light housing to release it from the niche, then gently pull the fixture onto the pool deck, keeping the cord intact. Disconnect the bulb by twisting or unsnapping it. This will depend on the fixture type.

Wear gloves, so oils from your hands don’t get on the bulb; they can shorten its lifespan. Put the fixture back together, and place it back into the niche. Turn the power back on and test the light before refilling the pool, if you drained it.

Disposing of Old Bulbs Responsibly

Check with local recycling centers for programs that accept specialty bulbs. If no recycling option is available, wrap the bulb in protective material to prevent breakage and dispose of it according to local regulations. LED bulbs are generally less hazardous but should still be recycled when possible.
