Fluorescent lamps are essential tools in every household. They provide wide lighting, save energy, have a long lifespan, and are affordable, making them the top choice for consumers today. When a fluorescent bulb is faulty or no longer illuminates, you can easily replace it by following the steps below.
1. Construction of fluorescent lamps
Fluorescent lamps consist of two main parts: the lamp fixture and bulb.
The lamp fixture includes a starter (a device to start the power supply for the lamp) and a ballast (a device used to regulate and stabilize the current).
The bulb has two electrodes at each end, made of tungsten. Inside the bulb, there is mercury vapor, inert gas, and a layer of fluorescent powder coated inside.

2. Lifespan of fluorescent lamps
A fluorescent lamp can operate for a maximum of about 10,000 hours (approximately 417 days). When the fluorescent lamp flickers, significantly reduces brightness, or doesn’t light up, it is time to check and replace the bulb.

Step 5: Install the new fluorescent bulb
You take the new fluorescent bulb, insert one end’s two electrodes first, and then work on the other end’s two electrodes. After that, gently adjust the bulb to fit properly and fix it.
Step 6: Supply power
You should turn on the power switch to supply power to the fluorescent bulb. If the bulb lights up, it means you have successfully replaced it.

4. Notes when replacing fluorescent bulbs
- If you have replaced the new fluorescent bulb but it still does not light up or flickers, the cause may lie in the starter of the lamp. The starter may be loose or broken, so you need to replace it to make the lamp work normally.
- If you have replaced the bulb and the starter but the bulb still does not light up, the ballast of the lamp is most likely damaged. When encountering problems with the ballast, you should seek help from an electrician to ensure the repair process goes smoothly and effectively.
