The light flashes/flashes at high frequency all the time. As it fades, the blinking becomes more pronounced. Very disappointed. Received 2 boxes, both have the same problem. Wouldn't recommend it.
Pros
DURABILITY. These lamps are an excellent energy saving replacement for older incandescent lamps with a total lifespan of up to 15,000 hours. You no longer have to constantly change lightbulbs.
