Usually older switches glow lamps used for this orientation light and often connected in series to the switched load. In order to avoid such a situation a bypass capacitor is needed in the ceiling lights, which thus minimize the coming voltage being persuaded. Don’t know why I did this but I took one of those three prong adaptors converters to two prong and to my surprise the light fixture didn’t light up. The neutral wire in the circuit may not be bonded to the earth or the earth wire is at a very high resistance creating a small current that lights your bulb. Cart. Carelessness or inefficiency of electrical installation caused LED light glows when off. The power switch is turned off. LEDs also require much less energy to create the same amount of brightness as incandescent lights, and last much longer. The diodes in your LED bulb can use the very low level of current to create light (other bulbs can’t do this). They use LEDs that emit light in the 940 nano-meter spectrum, which means that no glow is visible when it triggers. LEDs, on the other hand, have electrons that flow to create photons – light we can see. Usually many of the times the wiring works was accomplished with two way connections, resulting voltage carrying conductor might sometimes induce its voltage into the other conductors along the way as normally some of the conductors are far away from the switch. If you had a common cathode LED, that common cathode would be at 0V, so you'd need a HIGH output for the current to flow from there through the LED to 0V. Therefore it causes LED light to glow. I added a new Leviton DZR15 duplex receptacle with the intention using it to schedule when my Christmas lights are on. The serial connection of the glow lamp closes the circuit even when the switch is turned off. Blue LEDs came into the market in the early 1990’s and both of these, just as they are, are suitable for plant cultivation. This is embarrassing if LED Light Glows when off. There is one thing that is necessary to know; this glowing of the LED even if there is no electric supply provides no harm to the bulb let alone damaging it.
