5 reasons for frequent burnout

So, to your attention, the list of "culprits" because of which the incandescent lamp burns at the time of inclusion:

1. Overvoltage in the network. Scientists have proven that if the voltage deviates from the rated voltage (indicated on the package) even by 1%, the lamp life can be reduced to 14%. If you really have this problem, there are two ways to fix it: connect voltage regulator either buy fluorescent lampsthat can work with increased voltage in the mains. In the first case, although you will overpay the money, but completely eliminate the burnout of the bulbs, in the second, you will only slightly get away from the problem.
2. Poor electrical contact between wires and cartridge. The next reason that incandescent bulbs burn out can occur if the cartridge is made of cheap plastic. Burnt contacts contribute to additional heating of the bulb, as a result of which it can burn out. All you need to do is disassemble the lamp, check the cartridge and if there really is a problem in it, then you need to implement cartridge replacement to a new, better one. In addition, do not forget to strip the wires to a metallic color so that the new contact is reliable.
3. Poor connection of wires. If the mains voltage is normal and the cartridge is intact, but still when the light is turned on, the incandescent lamp burns out, you need to check all possible connections of the electrical wires, starting from the junction box and ending with the lamp itself. The malfunction can be anywhere: in the light switch, in the junction box and even on the chandelier itself. Check all wire strands, disassemble the light switch and after finding the problem area, fix the problem with a new connection. For this, it is best to use WAGO terminals.
4. Frequent on / off light. When we considered technical characteristics of incandescent lamps, we talked about such an indicator as the maximum number of inclusions, upon reaching which a tungsten filament burns out. There is nothing you can do, and you just have to replace the light bulb with a new one.
5. Incorrect operation. Well, the last reason why the lamp quickly burns out in the chandelier is due to increased humidity, temperature or vibration in the room. Observe the requirements indicated on the package and then the bulb will have a normal life.

That's all I wanted to tell you about this issue. We hope that from the listed reasons you have found your version of the malfunction and quickly solved the problem.We recommend that you install a surge protector in your home, as well as audit the wiring at least once a year. In this case, incandescent lamps will not often burn out when turned on, and all home appliances will be protected from power surges.
