I saw this for the first time when I visited a friend yesterday She had a couple of thee flickering candles that looked real.
They work on batteries and stay on for hours. I was so impressed that she gave me a couple as a Christmas gift. What she gave me was smaller and they are white.
Whoever invented this it was indeed a wise decision. It can easily replace those zero watt bulbs and I will surely do that.
Have you seen or have these artificial flickering candles?
