4 reasons why LED bulbs burn out quickly
Since the advent of LED lamps, manufacturers have positioned them as one of the most reliable. They last longer than others and save energy. Prices for such lamps are justified by performance characteristics. If the LED lamp burned out several times or faster than stated in the warranty card, you should look for the causes.
LED bulbs consist of a matrix with a large number of LEDs, and the assembly is closed with a durable bulb. Sometimes the cause of burnout is marriage. But more often the problems are related to wiring or voltage instability in the network.
No. 1. Low quality bulb
The most common cause of burnout is poor build quality and cheap materials. In order not to run into a fake, you should not pay attention to Chinese brands that have a low price, but do not guarantee quality. In the first days of use, the lamp can burn brightly, and lamps often have an attractive design, but these are the only pluses of Chinese products.
The main reason for the burnout of a cheap light bulb is the lack of drivers, which stabilizes voltage drops. Its presence is important when installing a lamp in a ceiling chandelier. If it has an LED backlight, a current stabilizer is usually installed. The output voltage for which it is designed varies over a wide range. The output current value will remain constant.

Brands to look out for when looking for a quality light bulb:
- Eurolamp;
- Lemanso;
- Feron;
- Philips;
- Osram;
- Lexman;
- Voltega;
- Maxus.
Since Chinese manufacturers are trying to save money and earn more, they install a ballast power supply instead of a driver. Its main disadvantage is lack of current stabilization functionwhich often causes the lamp to burn out.
No. 2. Defects in the wiring
To understand why the LEDs in light bulbs often burn out, you can contact an electrician to check the wiring. It is also worth paying attention to the condition of the cartridges in the chandelier. If the lamp burns out frequently in the same room, the problem is in the wiring. First of all, you should check the wire connections in the junction box.
Also, experts advise checking the connection of the ceiling lamp. If after checking it turned out that the wiring is working, but the diodes have not stopped burning out, check the cartridges. If they are burnt or broken, they need to be replaced. Sometimes a little helps repair. To do this, it is enough to strip the contacts and bend them to their original positions.
Number 3. Mains voltage instability
Burnout of an LED lamp due to voltage instability problems is often found in country houses. The surge can occur at the time of peak electricity consumption. If a lamp without a driver is installed in the chandelier, most likely it will burn out.
A power surge in a house or apartment can only be overcome by a high-quality lamp with a driver with a wide range. In most expensive light bulbs, it ranges from 160 V to 235 V. But if light bulbs from popular and expensive manufacturers burn out, the only solution is to purchase a voltage stabilizer.
No. 4. Frequent turning on and off
If it was not possible to understand the reason for the failure of the lamp, it makes sense to think about more banal things. One of them is the constant on and off. It is worth paying attention to switches that are equipped with indication. In order to be able to adjust the current to save electricity, the circuit breakers are equipped with dimmer. Before choosing a lamp for it, you should ask the consultant if it will work correctly.
If the package contains the sign shown in the picture above, the light bulb can be installed in a chandelier, the light intensity of which is controlled by a switch. If you purchase a non-dimmable lamp, due to the current that passes through it even when it is turned off, it will soon burn out.
The effect of frequent switching on and off on the life of LED lamps has not been proven.Most experts believe that this cannot cause a burnout due to the lack of starting electronics in the design.
Other reasons
Intensive use does not affect the life of the bulb. In the instructions you can find information that the number of inclusions is not limited. But this only applies to expensive brands.. Chinese manufacturers cannot boast of such a feature. Therefore cheap light bulb may burn out due to frequent use.

Chandelier defects can also cause combustion. In order not to encounter such a problem, when choosing a lamp, you should pay attention to:
- lighting area;
- ammo quality;
- lifetime;
- material of manufacture;
- the ability to adjust the brightness of the light;
- power stability, which will affect the period of operation.
If the light bulb often burns out and the cause is not found, a voltage converter should be purchased and installed.
4 more main reasons are described in the video.
Consult an electrician to determine the type of inverter. If the ice constantly burns out. light bulbs in spotlights, the lack of a converter is not the only cause of the problem. This is often due to a poor quality power supply, insufficient power, or an incorrect backlight power circuit.
