Unstable Power Supply Voltage
Flickering of grid lights is generally caused by an unstable power supply voltage. When the supply voltage is too low or too high, the brightness of the bulb changes, causing flickering. In addition, fluctuations in the mains voltage and voltage spikes can also cause flickering.
Circuit Design Faults
Flickering of grid lights can also occur when there are faults in the circuit design. For example, a faulty inductor coil or filter capacitor in the switching power supply can generate electromagnetic interference that affects the bulb brightness, causing flickering.
Short Bulb Lifespan
A short bulb lifespan is also a factor contributing to flickering of grid lights. When a bulb reaches a certain lifespan, it will automatically flicker or turn off.
Faulty Lamp Base
A poor lamp base connection can also cause flickering of grid lights. In this case, poor contact between the lamp base and the bulb will occur, causing flickering.
