We are replacing CFL lights with LED. It is expected that LEDs have longer life times. However we are facing frequent issues with LEDs such as blinking. The vendors give only 2 yr warranty with life time 30,000 hrs to 50,000 hrs. However we are not able to resolve the issue of blinking of LEDs. Could any one guide me on this to find what is the cause of blinking. Is it a LED driver issue ?

I've seen this issue in the parking lot of my apartment and I enquired. Though not convincing, I was informed that the driver component of the LED bulb gets affected by the voltage spikes. 

I'm not sure about the exact cause of this, and curious to know. Let's see if someone knows.

Fluctuations in voltage or frequency can cause flicker in LED lighting. Low cost unbranded LED lamps seem to be particularly susceptible. I have both in my house. The known high end brand has not failed while the low cost ones supplied by the electricity board failed often. I am replacing the failed ones with the more expensive branded products, which are fine in the same duty.

I know that we have considerable fluctuations because I check the voltage with a digital meter.

There can be many causes behind the blinking of Lights. For example, Loose light plug, Faulty light, Sensory overload on a circuit and Voltage fluctuations.
