Effect of Change in Frequency on Voltage

LED 230 Volt bulbs are directly related to the EDF power grid that delivers a voltage of 230 Volts (-5% / + 10%), which vary the tension of your network domestic outside the usual line 220/240 Volts.

These increases or decreases tension are necessary for the proper functioning of the electric network and adapts to changes in consumption.

What is the influence of the change of voltage?

A LED light bulb works in a range of voltage and intensity very targeted. When you move away from this beach, the operation is most optimal. To regulate these parameters, one bulb is equipped with an electronic circuit with component which ensures a voltage and a current stable. However, when input voltage is outside the range 220/240 Volts, these components can no longer ensure the ideal intensity and tension that is intended to cause a slight flicker.

This explains why all of the light bulbs can flicker at the same time.

This phenomenon degrades the LED life expectancy?

No, this flicker is not harmful to the life expectancy of your LED lamp from http://www.healthvv.com/2016/06/19/led-bulbs-for-fluorescent-fixtures/. It only translated output of the input voltage of the 220/240 Volts range the bulb through its electronic circuit to be adapted.

This phenomenon occurs with other light sources?

Yes, the flickering occurs also with halogen bulbs, incandescent or CFL but still usually imperceptible to the human eye.

How to prevent this flicker?

There is no reliable means to deal effectively with this glitter. If you live in a region strongly subject to the difference in voltage, you can install bulbs type MR16 12 volt including the input voltage and regulated by a current transformer 12 volt DC. This change of installation will solve the whole problem.
