How To Winterize Pool Lights?

Nowadays, pool lights are quite hyped by people. That’s because, other than lights, it creates an aesthetic vibe to the pool. In summer, everything is fine, and you can swim over. However, in winter, the weather doesn’t allow you to swim. Therefore, you have to close the pool during the season partially. You may be worried that cold temperatures will damage your pool lights, this blog will tell you if and how to protect your pool lights from freezing.

What Do Winterize Pool Lights Mean?

Winterising a pool light means protecting the pool light during the winter months to prevent it from being damaged by cold or freezing temperatures. Damage generally means that the pool light will not light up as winter passes and temperatures rise.

Do pool lights need to be protected from freezing?

Generally speaking, pool lights do not require frost protection. This is because most pool lights use solid state lighting (SSL) technology such as LEDs. This lighting technology uses semiconductor materials to emit light, rather than traditional incandescent filaments or gas discharges.LED lights perform better at low temperatures, and when the ambient temperature falls below 25°C (77°F), it lowers the junction temperature to produce more light than usual.

Of course, other electronic components within the pool light may also be affected by extreme low temperatures. Therefore, in countries with cold climates such as Canada, Russia, Iceland and Norway, it is necessary to consider frost protection when purchasing and using pool lights.

WAKING Lighting manufactures LED pool lights that are completely sealed to withstand operating temperatures of -4°F (-20°C) and do not require freeze protection in most areas.

How To Winterize Pool Lights- The Steps

There are many different processes for winterizing those lights. However, try this one, as it clearly shows what you have to do. Also, the process is quite simple and convenient for everyone to use. You won’t require any professional assistant or a company to pay for this job.

So, let’s start with the steps.

Locate the pool light and its power supply cable

The first step in winterizing your pool light is to locate the light and its power supply cable. This will allow you to access the light and disconnect it from the power source.

Remove the plastic cap covering the cable

Check for the power supply cable

Use a flat screwdriver or other sharp, pointed object to remove the plastic cap that covers the power supply cable. This will expose the cable and allow you to disconnect it from the bulb.

Disconnect the power cable from the bulb

Once you have removed the plastic cap, you can disconnect the power cable from the bulb by separating the live and neutral wires. This will cut off power to the bulb and prevent it from being damaged by freezing temperatures.

Fold the wires connected to the bulb inward

After disconnecting the power cable, fold the wires that are connected to the bulb inward towards the bulb holder. This will help to protect them from damage during the winter months.

Dismantle the lock

Gently twist the lock that holds the bulb in place in a clockwise or counterclockwise direction to dismantle it. This will allow you to remove the bulb from its connection.

Detach the light bulb from its connection

Detach the light bulb

Once you have dismantled the lock, you can detach the light bulb from its connection by covering one end of the bulb with your hand and twisting or pulling it to remove it from its connection. Be sure to handle the bulb carefully to avoid damaging it.

Place the bulb in a dry location

After detaching the light bulb, place it in a dry location where it will be protected from moisture and freezing temperatures during the winter months.

Insert a winterizing plug into the hole where the bulb was installed

Fix the winterizing plug

To prevent water from entering and freezing in the hole where the bulb was installed, insert a winterizing plug into this hole and twist it in an anticlockwise direction to secure it in place.

Well, the antifreeze work of the pool lights is completed.

It is important to note that this is a more conventional method of winterizing pool lights. For some specific models, there may be other methods that are more appropriate for your pool light. For example, AQUALUMINATOR pool light winterize. If you still have questions about the methods described above, it is best to consult a professional or refer to your pool light’s manual.

What other pool fixtures need to be freeze-proofed?

In this blog, I’ve said that most people don’t worry about frost protection for pool lights except in extremely cold areas. However, other parts of the pool unit are not as freeze resistant as pool lights. Therefore, it is still important to take the following steps to close your pool and protect it from freezing temperatures:

  • Before closing for the winter, make sure you clean the swim. This includes removing debris and dirt from the bottom of the pool, such as leaves and debris
  • Lower the water level to ensure that there is enough room to expand when it freezes. It is usually more common to lower the water level below the waterline tile or pool wall tile
  • Turn off pool equipment, including pumps, filters, etc. Ensure that the drainage system is emptied of water to prevent freezing and damage
  • Make sure to drain all pool pipes; this prevents water from freezing in the pipes and causing a rupture
  • Install proper winter covers to protect pool water and equipment. These covers are usually sturdy and waterproof, preventing leaves, debris and snowfall from entering the pool


Well, it is essential to winterize pool lights. Therefore, you shall look into the steps required to do this job. Without professional help, you would do this job properly.
