How to Replace Under Cabinet Light Bulbs

What is an Under Cabinet Light Bulb?

An under cabinet light bulb is a small, low-profile light fixture that is installed underneath office cabinets to provide additional lighting and visibility for food preparation and other office tasks. These bulbs are typically smaller in size compared to traditional household light bulbs and are designed to fit into compact spaces.

Types of Under Cabinet Light Bulbs

There are various types of under cabinet light bulbs available on the market, each with its own unique features and benefits. Some common types include:

LED Bulbs:

These are energy-efficient bulbs that produce less heat and have a longer lifespan compared to traditional incandescent bulbs.

Fluorescent Bulbs:

Also known as CFLs (Compact Fluorescent Lamps), these bulbs use low energy to provide bright, white light.

Halogen Bulbs:

Halogen bulbs produce a warm, yellow-toned light and are known for their high-intensity brightness.

Xenon Bulbs:

Similar to halogen bulbs, these produce warm-toned light but have a longer lifespan.

Necessary Tools

Before replacing your under cabinet light bulbs, make sure you have the necessary tools on hand. These may include:

Step Stool or Ladder to Access the Light Fixture

Since under-cabinet light fixtures are installed above eye level, having a step stool or ladder will make it easier to reach and replace the bulb.

Protective gear

It is always recommended to wear protective gear, such as gloves and safety glasses when replacing light bulbs to prevent any potential accidents.

New Light Bulbs

Make sure you have the appropriate type of replacement bulb for your under cabinet light fixture. It is also a good idea to have extra bulbs on hand in case of future replacements.

Cleaning Supplies

It’s a good practice to clean the area around the light fixture before and after replacing the bulb to ensure proper lighting and prevent any buildup of dust or debris.

10 Step-by-step Guidelines on How to Replace Cabinet Light Bulbs

Step 1: Identify the Type of Bulb You Need to Replace

As mentioned earlier, there are various types of under-cabinet light bulbs. Before replacing a bulb, it is essential to know the type and size you need. You can refer to the manufacturer’s guide or take a picture of the current bulb to compare it with the options available at the store. It is also a good idea to turn off the power supply to the fixture before handling the bulb.

Turn Off the Power Supply

Step 2: Prepare your Work Area

Clear the area around the light fixture and make sure you have enough space to work comfortably. Lay down a cloth or paper underneath the work area in case of any accidental drops or spills. You can also use a flashlight to improve visibility in dimly lit areas. The cleaner the work area, the easier it will be to replace the bulb. You can also turn on the overhead lights or open a window for additional lighting. But remember to turn them off before working on the fixture.

Step 3: Access the Light Fixture

Use a step stool or ladder to reach the light fixture. Make sure it is safely secured and you have a steady footing before proceeding. But if the fixture is within reach, you can skip this step. The key is to have a clear view of the fixture and enough space to maneuver comfortably. You can also ask for assistance from someone to hold the ladder or step stool in place. It’s always better to be safe than sorry.

Step 4: Remove the old Bulb

Once you have access to the light fixture, remove the old bulb by twisting it counterclockwise. For LED and fluorescent bulbs, gently wiggle and pull them out of their sockets. If the bulb is stuck, don’t force it as you might break it or damage the fixture. Instead, try using a small suction cup or a pair of rubber gloves for a better grip. However, if the bulb is shattered or broken, use a broom and dustpan to clean up the area before proceeding. The last thing you want is to step on a piece of broken glass.

Step 5: Clean the Fixture

Before installing the new bulb, take this opportunity to clean the inside of the fixture. Use a dry cloth or compressed air to remove any dust or debris that may have accumulated in the fixture. This will help improve the brightness and lifespan of the new bulb. It’s also a good idea to wipe down the exterior of the fixture and the surrounding area for a polished finish. But make sure the fixture is completely dry before proceeding. It’s a safety precaution to avoid any potential electrical hazards.

Step 6: Install the New Bulb

Gently screw the new bulb into place, making sure it is securely fitted. If you are using an LED or fluorescent bulb, push and wiggle it into the socket until it clicks. Avoid over-tightening as this may damage the fixture. You can also refer to the manufacturer’s guide for specific instructions on installing their bulbs. The same goes for xenon and halogen bulbs, as they may require a different method of installation. You can also use gloves or a cloth to handle the bulbs, as oils from your skin can affect their lifespan.

Step 7: Turn on the Power

Once you have successfully replaced the bulb, turn on the power supply and test if the new bulb is working correctly. If it doesn’t turn on, double-check if it is securely fitted or try a different bulb. It’s also a good idea to wait a few minutes after turning on the power before testing if the bulb is working. Some bulbs may take a few seconds to reach full brightness. It’s also a good idea to test the switch or dimmer for any malfunctions. The last thing you want is to replace a bulb, only to find out that the issue lies with the switch or dimmer.

Step 8: Check for Proper Lighting

After testing, check if the light is evenly distributed and there are no dark spots or flickering. If you notice any issues, turn off the power supply and try reinstalling the bulb. You can also clean the fixture and surrounding area again to see if that improves the lighting. If all else fails, it may be a sign of a faulty fixture or wiring, and you may need to consult a professional electrician. There may also be an issue with the power supply or circuit, so it’s best to have a thorough inspection done. It’s always better to be safe than sorry when it comes to electrical work.

Step 9: Dispose of the Old Bulb

Properly dispose of the old bulb by wrapping it in a cloth or newspaper and placing it in a sealed plastic bag. This is to prevent any broken pieces from causing harm and also as a safety precaution for those handling the garbage. But if the bulb is still intact, you can also donate it to a local recycling center or program. You can also check with your local government for proper disposal methods in your area. The key is to handle the bulb with care and avoid any accidents.

Step 10: Clean up

Dispose of any used cleaning supplies and put away any tools or equipment that you may have used. If there are any spills, make sure to clean them up before storing the cleaning supplies. This will prevent any accidents or hazards when using them in the future.

You can also take this opportunity to organize and declutter your work area, making it easier for the next time you need to replace a bulb. And with that, your under cabinet light is now as good as new and ready to brighten up your space once again! 

So remember, always handle bulbs safely, turn off the power supply before replacing them, and follow these simple steps on how to replace under cabinet light bulbs for a hassle-free experience. Happy lighting!
