How Much Does Pool Light Replacement Cost? [2026 Data]

In 2026, the national average cost for pool light replacement is $625 per fixture. Most homeowners spend between $500 and $900, with the final cost driven by light type, wiring updates, and permit requirements.

Pool Light Replacement Cost Factors: What Determines the Price?

The total cost to replace pool lights depends on several factors, including the number of fixtures needed, the type of pool lights, and labor costs if you hire a local swimming pool repair company. Getting a clear picture of all these factors before you start helps you build a realistic budget and avoid surprises.

Type of Pool Light

Pool light replacement costs range from $450 to $1,700 per fixture, with the type of light being the primary cost factor. Homeowners can choose among incandescent (the most affordable), LED (the mid-range option), and fiber optic (the most expensive). The table below breaks down pool light replacement costs by type: 

LED

LED pool light replacements cost $700 to $1,500 each, or $50 to $650 for just the bulb, depending on the light's size. Although the upfront cost is higher than that of other pool light types, LEDs deliver strong long-term value through a lifespan of about 20,000 to 30,000 hours and low energy consumption. Replacing them far less frequently than incandescent or fiber optic lights means lower utility bills and fewer replacement costs over time.

Fiber Optics

Fiber optic pool light replacement costs $1,300 to $1,700 per fixture, or $20 to $60 to replace just the bulb. These lights produce a softer, more subtle glow—a good fit if you prefer ambient lighting over full backyard illumination. Fiber optics have lost ground to LED lights in recent years, though they do outlast incandescents with a lifespan of about three to seven years.

Incandescents

Incandescent pool light replacements cost $450 to $650 per fixture, or $20 to $70 for a new bulb, making them the most affordable pool light option. Their lower upfront cost comes with a trade-off: incandescent lights last only about 1,000 to 5,000 hours, or roughly one to three years of use. If you replace lights frequently, the ongoing costs can add up compared to longer-lasting LED alternatives.

Number of Pool Lights Needed

Pool lights cost about $625 each and are typically sold individually, so your total will scale directly with the number of fixtures that need replacing. Most homeowners only need to replace one light at a time as each burns out or becomes damaged. If your pool is older and all the lights are nearing the end of their lifespan, replacing them all at once may be the more practical approach.

Existing Wiring

Updating pool wiring costs around $350 to $4,000, depending on the scope of the electrical work required. An electrician will handle the wiring at $50 to $100 per hour, and you should also budget $50 to $350 for building permits and up to $100 for electrical wiring inspections. These added costs are worth factoring into your budget before the project begins, especially if you are switching light types or adding new fixtures.

Labor

For broken pool lights, you should call a professional pool service or a pool electrician, who will charge about $50 to $100 per hour. Unlike swapping a standard indoor bulb, replacing a pool light requires handling electrical components in close proximity to water, which poses real shock risks for untrained homeowners. Hiring a licensed professional is the safest way to get the job done correctly.

Ongoing Pool Light Costs: What to Budget For

Owning a pool means budgeting for more than just light replacements—wiring updates, routine maintenance, and occasional repairs all add to your long-term costs. You may need an electrician to install additional wiring for more lights or to upgrade the pool wiring when transitioning from fiber-optic pool lights to LEDs. Planning for these ongoing expenses upfront helps you avoid unexpected costs down the road.

Maintenance

Swimming pool maintenance costs about $110 to $375 per month, with electricity running around $300 a year. If you prefer to hand off the work, hiring a local pool service runs around $75 to $100 per hour, and hiring a pool maintenance pro often means access to monthly or seasonal maintenance contracts. Keeping your pool clean and well-maintained extends the life of all its components, including the lighting, and reduces how often you need replacements.

Repairs

Pool light repair costs about $65 to $150 per light and typically involves replacing a worn-out gasket or conduit seal. A simpler repair—swapping out a burned-out bulb—costs about $20 to $100 and is worth considering if the fixture itself is still in good condition. Repairing rather than replacing can save you a significant amount when the underlying fixture is sound.

How to Save on Pool Light Replacement

Replacing pool lights can give some people sticker shock when compared to the cost of standard indoor light bulbs. While the higher cost is due to added safety features for pool lights, you can still save money on replacements with a few handy tips.

Ask About Discounts

Are you ordering multiple lights from a pool company? Check in about discounts for ordering items in bulk. Some companies may also offer sales on pool products in fall and winter, when fewer people are buying them. 

Opt for LEDs

Hear us out—while the up-front cost of LED pool lights is more expensive than incandescent or fiber optic lights, you’ll actually save money in the long run. LED pool lights use less energy and need to be replaced far less often, about every ten years, compared to the other pool light types.

Replace Just the Bulbs

If your light fixtures are in good shape, you can save money by only replacing the inner light bulb rather than the entire unit. Pool light bulbs are about $20 to $100 each, while the whole unit will cost about $625. Of course, if the unit is old or in poor condition, it’s important to replace the whole thing to minimize risk of electrocution from a faulty pool light.

Repair vs. Replace

Maybe the gasket of the pool light needs to be upgraded, but the rest of the fixture is in good shape. If your pool light can be repaired, hold off on a replacement. Repairing a pool light costs about $65 to $150 per light, compared to replacing a light for around $625.

Why You Should Hire a Pool Light Replacement Pro

To replace a pool light yourself, you'll spend $100 to $500 for the replacement light and bulb, or about $20 to $100 for just the light bulbs. But handling electrical components in a pool filled with water poses shock risks, so this job is best left to a pool repair expert near you. You'll pay $625 per light for a professional to replace the pool lights.
