What You'll Learn
Turn off the power supply
Before you begin to change a round fluorescent light bulb, it is important to prioritise safety by shutting off the power supply to the light fixture. This will prevent any accidents or mishaps during the process of changing the bulb.
To turn off the power supply, locate your home's electrical panel, which is usually found near the main breaker box. Once you have located the electrical panel, identify the breaker switch that controls the circuit that the light fixture is on. It is important to note that if your breaker switches are not clearly labelled, or if you are unsure which circuit the light fixture is on, it is recommended to turn off all potential circuits or the entire electrical supply to your home. This ensures that there is no power flowing to the light fixture, eliminating any potential safety hazards.
For added safety, you can use a no-touch voltage tester to double-check that the power is indeed off. Hold the voltage tester as close as possible to the light fixture to ensure that no electricity is flowing. This extra step can provide peace of mind and help prevent any accidental electrical shocks.
After confirming that the power is off, you can proceed to the next steps of changing the fluorescent light bulb. Remember to work carefully as fluorescent bulbs can break easily, and always ensure that the power is off before beginning any electrical work. Safety should always be the top priority when working with electricity.

Remove the light fixture cover
To remove the light fixture cover, you will need to identify how it is attached to the light. Typically, there are a few standard ways that light fixture covers are attached: with screws, with clips, or with a hinge. Once you have identified the method of attachment, you can proceed with the removal process.
If the cover is attached with screws, you will need to use a screwdriver to remove them. Make sure you have the correct type of screwdriver (either Phillips head or flat head) that fits the screws securely. Place the tip of the screwdriver into the head of the screw and apply gentle pressure while twisting the screwdriver in the counter-clockwise direction to loosen and remove the screws. Take care not to strip the screws by using excessive force or the wrong size screwdriver.
For covers that are held in place with clips, you will need to gently pry the cover away from the light fixture. You can use your fingers or a flat-head screwdriver for this task. Insert the screwdriver under the edge of the cover, between the cover and the fixture, and gently apply leverage to pop the cover out of the clips. Work your way around the perimeter of the cover, releasing each clip one by one. Be careful not to apply too much force, as this may damage the clips or the cover itself.
If the cover is attached with a hinge, you will usually find a latch or a clip holding the cover in place. To remove this type of cover, locate the latch or clip and gently lift or depress it to release the cover. The cover should then swing open on the hinge, providing access to the fluorescent tube. In some cases, the hinge may be tight, so take care when opening the cover to avoid any sudden movements that could cause the cover to snap.
In some cases, the light fixture cover may have a combination of these attachment methods. For example, it may have both screws and clips holding it in place. In this case, you will need to remove the screws first and then gently pry the cover away from the fixture to release it from the clips. Always be mindful of the delicate nature of light fixtures and use appropriate force when removing the cover to avoid any damage.
Once you have successfully removed the light fixture cover, set it aside in a safe place where it will not be damaged or accidentally knocked over. Be sure to handle the cover with care, as some covers can be fragile and prone to breakage if dropped or mishandled. With the cover removed, you will now have access to the fluorescent tube and can proceed with replacing the bulb.

Release the spring-loaded clip
To release the spring-loaded clip, you will need to understand the mechanism of the clip and the bulb. Fluorescent light bulbs are held in place by J-shaped, spring-loaded metal clips. These clips are designed to keep the bulb secure and in place. Typically, there are one or two such clips holding the bulb in place.
To release the clip, you must first locate it. It is usually found along the perimeter of the fixture where it meets the ceiling. Once located, use one hand to hold the bulb in place. With your other hand, you can now release the spring-loaded clip. Flex the clip away from the bulb. If there are two clips, repeat the process for the second clip. Make sure to flex one clip at a time if there are multiple clips.
The spring-loaded clip is an essential part of the light fixture. It ensures the bulb is held securely in place. When replacing a bulb, it is important to flex the clip out of the way so you can position the new bulb in place. Once the bulb is positioned, the clip can be guided back into place. This will ensure the bulb is held securely and safely.

Insert the plug into the pins
Before you insert the plug into the pins, make sure you have turned off the power to the light fixture at the electrical panel. This is important for safety reasons.
Now, grab the plug at the end of the wire that connects to the ballast. Carefully, insert the plug into the pins on the new bulb. Ensure that the pins on the bulb are inserted completely into the plug. Work slowly and carefully so that you do not accidentally break the bulb.
If you had to leave your home to purchase a replacement bulb, make sure to double-check that the power to the light fixture is still switched off at the electrical panel before you insert the plug into the pins of the new bulb and proceed with the installation.
In some cases, you may need to push the bulb towards the ends to insert it properly. Some older single-pin lamps were held in this manner, with one spring-loaded end. There may be a version of this with two pins on each end.
If you are in Australia, it is important to note that all electrical work needs to be carried out by a licensed electrician. If you are uncomfortable with any step of the process, it is recommended that you hire a professional electrician to assist you.

Turn the power back on and test the bulb
Once you've replaced the bulb, it's important to take some precautions before turning the power back on. Start by ensuring that you didn't accidentally touch any part of the new bulb with your bare hands. If you did, use a soft cloth to gently wipe down the bulb, removing any fingerprints or marks. Oils from your skin can damage the bulb over time and shorten its lifespan. Next, carefully re-install the bulb cover or diffuser, making sure it's securely in place. Now you can turn the power back on at the switchboard or fuse box. If you have a dimmer switch, ensure it's turned up to full brightness. After turning the power on, there should be an immediate, bright light. If the bulb doesn't light up right away, don't panic. Some new fluorescent bulbs can take a few seconds to warm up and reach full brightness. Give it a moment and observe if the light gradually brightens. If the bulb still doesn't light up, or if it flickers or makes a buzzing noise, there may be an issue with the ballast. The ballast is the component that regulates the amount of electricity flowing to the bulb, and it may need to be replaced. In this case, it's best to consult an electrician or a knowledgeable staff member at your local hardware store for advice on ballast replacement. If the bulb lights up but appears dim or emits a humming noise, try replacing the starter. The starter is a small, cylindrical component that sits near the bulb and is usually inexpensive and easy to replace. Finally, if your fluorescent light fixture has a diffuser or cover, ensure it's properly cleaned and maintained. A dirty or dusty cover can reduce the amount of light that shines through, making the bulb appear dimmer than it is.
