Wayne Davis I believe that all the wiring is acting like an antenna and the ground in the home is allowing a crystal radio affect on the LED bulbs, capacitors will deplete after they lose their charge.

roman kalinchuk This is not wasting any more power than a standard bulb, so no need to worry about it costing you money. The led is just very efficient, so its able to glow from that tiny amount of current. Other led bulbs would probably have a voltage cutoff to prevent the glow, but they would not work with a dimmer circuit. I've had dim-able leds that would glow very faintly when turned off. Not bright enough to bother anyone, though.
