LED lights may have annoying noise when used, but the noise is often not caused by quality problems. It is a common problem caused by a variety of circumstances. There are usually three situations as follows:
- High-power appliances in the same circuit.
When high-power appliances, such as microwave ovens and air conditioners, are turned on, they may cause noise or flicker due to excessive voltage. This is because the LED light is trying to adjust the voltage to accommodate this situation. This condition can also lead to circuit overload, which may be harmful to both lights and appliances.
The best way to solve this problem is to have a professional electrician evaluate your circuit and separate them into two circuits.
- The use of incompatible dimmer
Some dimmers may be designed for CFLs or incandescent lamps, and the rated power will be very high, while the watt LED lights need is very low. An incompatible dimmer will run it with unstable voltage, which may cause noise or low dimming.
The best way to solve this problem
- Loose connection and wiring
The main reason LED lights causing buzzing or flickering is that there are voltage fluctuations in your wiring system. If the electrical wiring in your home is loose, your LED lights are likely to buzz. Especially for recessed light, it’s hard to find out the incorrect wiring on the ceiling. Loose connections in the circuit may cause by a collection of dust in the circuit.
The best way to solve this problem is to check the wires and connections to see if they need to be replaced and to safely clean the dust off the connections.
