An Overview of Inground Swimming Pool Lights

Everyone dreams about installing an inground swimming pool in their backyard. If you want to make this dream come true, you should consider installing an underwater light in it too. An underwater light can make your pool look so much more beautiful and exciting to your guests. Most importantly, it will keep them safe when they swim at nighttime.

Here we will discuss everything you need to know about inground swimming pool lights.

The Cost of Inground Pool Lights

Inground pool lights come in different colors and styles. Most of them are LED pool lights with multiple colors. You need to flip a switch to alternate the colors, making the pool water look that color. Do not construction your pool without considering your lighting options first.

The underwater lighting system has to be installed at the same time as the construction of the pool. The only exception is if you purchase portable pool lights that float on the top of the water or sink to the bottom of the water. But those are lower quality lights.

The smallest pool lights cost between $700 and $900. They use LED bulbs. If you want to pay more for fiber optic lighting, it will cost you between $1,300 and $1,700. You won’t need to do any maintenance other than replacing the bulbs after they stop working.

Is it Worth Getting Pool Lights?

Yes! Pool lights allow swimmers to use the pool at any time of the day or night. When you dive underwater, the lights will let you see much more clearly. It is crucial to have visibility under the water, especially if you or your children use the pool at night. You can easily watch your kids because the lighting allows you to see them in the water.

The Number of Lights for Your Pool

The number of lights you’ll need depends on your pool’s size and the type of lighting system you choose. For instance, if you have a fiberglass pool that is 25 feet long, you can use one LED light to illuminate the entire pool. If the pool is over 30 feet long, you should use two lights.

Of course, the safest choice would be to get two lights. That is ideal for most pools. The only exception is an extra-large pool. Then you can use three lights for it.

The Main Types of Pool Lights

Below are the three primary types of pool lights.

1) LED Lights

Light Emitting Diodes (LEDs) use moving electrons inside of a semiconductor material to illuminate. There are no filaments in them, which means they produce no heat. The most popular feature is their ability to change colors. You could create the perfect party setting in your backyard with multicolored pool lights.

LED bulbs last for up to 30,000 hours. It is much longer than the incandescent bulbs and fiber optics that last up to 5,000 hours and 6,000 hours, respectively.

Bigger LED pool lights cost between $1,000 to $1,500 on average. They are for pools with concrete or vinyl liner. If you choose smaller LED lights, the cost is around $700 to $900.

2) Fiber Optic Lights

 Fiber optics trended like crazy in the early 2000s. But then, LED technology came along and wiped out its popularity. However, some people still prefer the fiber optic light design for their swimming pools. It features a light bulb inside of a dry box on the pool patio.

A series of fiber optic cables are connected to the bulb inside the box. The other end of the cables is connected to the inner pool walls. When the light bulb shines, the light passes through the cables and enters the water. To change the color, you can install a color wheel in the dry box. As the light shines through the color wheel, it changes color on the other side.

The only downside is that fiber optic lights are not as bright as LED lights. And for that, you have to pay more money for the fiber optic lights. That is primarily why people have trended toward LED pool lights.

Fiber optic pool lights cost between $1,300 and $1,700.

3) Incandescent Lights

Incandescent lights are the oldest type of pool lights. Each one uses a filament to produce a bright shining light inside of a bulb. The filament is a wire with an electrical current flowing through it. As the filament gets hotter, the light glows brighter.

A colored lens is required if you want to change the color of an incandescent bulb. It is not as bright as an LED light, though. What’s worse is that incandescent lights have a shorter lifespan than LED lights. There is no upside to using incandescent lights anymore, other than they’re cheaper to buy.

Incandescent pool lights cost between $450 and $650.


Maintenance is not required. You’ll only need to replace the light bulb when it stops working. In most cases, the water level won’t need to be lowered to replace the light bulb. If the bulb’s housing unit can be elevated above the water, you can replace the bulb without changing the water level. The replacement shouldn’t take more than 5 to 10 minutes to complete.

If the housing cannot elevate, then you might need to replace the housing unit entirely. It will take a much longer time, though. That is why a fiber optic light system might be ideal if you want a fast and easy way to replace a bulb. The fiber optic light system keeps a dry box cover on the patio. It means you don’t even need to get into the water to change the bulb. Just open the cover, take the dead bulb out and put the new bulb into it.

Bulb Replacement Costs

  • A large LED bulb costs between $450 and $650.
  • A small LED bulb costs between $50 and $350. Some models have varying prices.
  • A fiber-optic bulb costs between $20 and $60.
  • An incandescent bulb costs between $30 and $70.


Pool lights are safe for the most part. Just make sure you have a professional person install the pool lights. You must maintain compliance with all local building codes and the specifications of the manufacturer. Do not attempt to perform the installation yourself. A lousy installation might cause a safety hazard.

Seven color options are available. The lights gradually transition from one light to another light while in the water. The batteries are strong enough to give you a maximum of 100 hours of constant illumination. When it comes time to replace the batteries, the process is simple.

How We Rated These Choices

We researched dozens of different pool lights to find these top three choices. Here are the considerations that went into our choices:


Pool lights are supposed to make your pool water brighter. If you have a large pool, you’ll need to purchase lights with more voltage or wattages. Smaller swimming pools won’t need as much brightness. Therefore, you can get away with one or two lights for them.

Simple Installation

Your pool lights must be compatible with your swimming pool if you want them to get installed correctly. For example, if you have a 12-volt pool light system, it requires 12-volt light bulbs. On top of that, you must install the light system while you construct the pool.

For this reason, most people choose floating pool lights because they’re so much less hassle. And if you already have an existing swimming pool without lights, it is much cheaper to add floating lights.

Durability and Strength

Since you’re investing money into your pool lights, they should at least be durable and long-lasting. You shouldn’t have to replace lights after a couple of months. Choose lights with high-quality materials.

For example, pool lights made of plastic and vinyl are much better than lights made of paper and foam. Durable lights ensure you won’t need to make as many repairs or replacements.

Other Features

Some of the best pool lights on the market come with additional features. That is why so many customers love them. The ability to switch the colors of the lights is one notable feature. Any other add-ons or accessories included are even more appreciated, especially if you’re having events or parties in your backyard. Accessories can make those gatherings much more fun.

The Top 3 Swimming Pool Lights of 2021

LED Lights

If you want fancy lighting colors, you’ll find plenty of colorful LED bulbs available for pools. Most LED lights come with a 7 to 15-year warranty if you purchase them from a reputable supplier. You’ll also save money on your power bill each month because they consume less energy. The LED lights are cheap to purchase too.

The most challenging thing is changing the bulbs. The housing setup will determine how long it will take to change the bulb. It might take you over 30 minutes with specific setups. If you host pool party events regularly, then prepare yourself to change the LED bulbs more frequently.

Halogen Lights

Halogen lights are the traditional lighting source for swimming pools. You can install them on above-ground pools or in-ground pools as well. The biggest advantage of halogen lighting is how easy it is to change the halogen bulbs. It is much easier than changing LED bulbs.

Unfortunately, halogen lightbulbs do not have a long lifespan. They also consume more energy, which will increase your monthly power expenses. The only two color options available are blue and yellow.

Fiber Optic Lights

Fiber optic pool lights offer the most flexibility. For instance, you can install colorful fiber optic lights beneath the water and change the water surface’s color. The lighting can change colors too. If you want to add excitement and creativity to your pool lighting setup, you must choose fiber optic lighting. The fiber optic lightbulbs can be changed quickly.

On the downside, fiber optic lights do not have a long lifespan. They’ll consume a lot more energy than LED lights and halogen lights.
