Why is the light flashing?

Flickering or blinking bulbs from time to time is a problem familiar to many people in our country. Probably, have you ever fought with such a capricious lamp, which categorically refuses to work in a stable mode. In order to eliminate this problem, you must first understand the causes of it. In fact, the light in the house may blink or flicker for several different reasons. Consider the main ones.

Why is the light flashing?

  • The first reason is that you changed the light bulb to an energy-saving one (LED or fluorescent), and the switch has a small light bulb showing the way to the switch in the dark. In order for your energy-saving lamp to stop blinking, you will have to remove this light in the switch. It's pretty simple - disassemble it.
  • The second reason - in the neighborhood with you someone conducts electric welding. During the operation of a powerful welding machine in a power supply network that is not designed for pulsed welding currents, a short-term high voltage drop occurs, as a result of which the lamps in the house begin to blink frequently.
  • The third reason is a faulty wiring.If the wiring in the house is old, hidden cracks may form in the wires of the wires. When a large number of powerful household appliances are simultaneously turned on in such a faulty network, the worn out wires overheat, this overheating leads to the fact that the lamps in the house start to flicker or wink.
  • The fourth reason - defective contacts in the switch or in the lamp holder. If the switched on lamp starts to wink, and a characteristic crackle is heard from the switch, then the whole reason lies in the poor contacts in the switch. If everything is in order with the switch, oxidized contacts in the lamp holder may cause the blinking, or the light bulb may simply not be completely screwed into this holder.
  • The fifth reason is that the transformer substation is unstable, which supplies electricity to your home. In such a case, at times of peak load or during switching, the power lines may blink throughout the house.

Why is the power saving light off flashing?

The first reason: the lamp is connected to the network using a switch that has an LED backlight. To prevent the lamp from blinking, you can:

  1. Change it to an ordinary incandescent lamp.
  2. Replace the illuminated switch with an ordinary switch.
  3. Disconnect the LED backlight from the network (open the switch and have a snack on the wire suitable for the backlight).

The second reason is incorrect connection of the lamp. Sometimes the energy-saving lamp may flash when the phase and neutral wires are connected to its switch in the wrong order. In this case, in order to eliminate the flashing of the lamp, it is necessary to swap the phase and neutral wires in the switchboard located at the entrance to the apartment.
