How to tell if the light tube is broken
Lamps are common lighting equipment in daily life, but they will inevitably malfunction after being used for a long time. How to quickly determine whether the light tube is broken? This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with detailed judgment methods and solutions.
1. Common symptoms of lamp failure
When there is a problem with the lamp, there are usually the following symptoms:
| performance | Possible reasons |
|---|---|
| The lamp doesn't light up at all | Damaged lamp, faulty ballast or power supply problem |
| Lamp flashes | Lamp aging, poor contact or unstable voltage |
| The lamp is black | The lamp life is coming to an end or internal gas leaks |
| Lamp brightness dims | Lamp aging or insufficient voltage |
2. How to judge whether the lamp is broken?
Here are a few simple ways to judge:
1. Observe the appearance of the lamp
Check whether both ends of the lamp are blackened. If the blackness is severe, it means that the lamp has aged and needs to be replaced.
2. Judge by listening to the sound
If the lamp emits a noticeable "buzzing" sound when the switch is turned on, there may be a problem with the ballast or lamp.
3. Substitution test
Replace the suspected problematic lamp with another working lamp and test it. If it still does not light up, it is basically certain that the lamp is broken.
4. Multimeter test
Use a multimeter to measure the resistance at both ends of the lamp. If the resistance is infinite, it means there is a circuit break inside the lamp.
3. Common problems and solutions for lamps
| question | solution |
|---|---|
| The lamp doesn't light up at all | Check the power supply and replace the lamp or ballast |

| Both ends of the lamp are bright but the middle is not bright | Replace starter or lamp |
| Lamp brightness is insufficient | Replace with new lamp |
4. Suggestions for purchasing lamps
If it is confirmed that the lamp is damaged, you need to pay attention to the following points when purchasing a new lamp:
1. Matching model
Confirm the power, length and interface type of the original lamp, and purchase products with the same specifications.
2. Choose a brand
It is recommended to choose lamps from well-known brands to ensure better quality.
3. Pay attention to color temperature
Choose the appropriate color temperature according to the usage scenario. Generally, the color temperature is around 4000K for the living room and 2700-3000K for the bedroom.
4. Environmental protection and energy saving
Give priority to LED lamps, which are more energy-saving and environmentally friendly although they are slightly more expensive.
5. Tips for daily maintenance of lamps
Tips to extend the service life of lamps:
1. Regularly clean the dust on the surface of the lamp tube
2. Avoid frequent switching of light tubes
3. Make sure the environment is well ventilated
4. Pay attention to voltage stability
5. Do not disassemble the lamp at will
Through the above methods, you can easily determine whether the lamp is damaged and take appropriate measures in time. If you still cannot determine the problem after self-inspection, it is recommended to ask a professional electrician to perform maintenance to ensure safe use of electricity.
