Yes it is leakage, often capacitive current between adjacent AC conductors in the run to the switch is sufficient to glow an LED. We have installed them to existing wiring in this job and i suspect the cables are all bunched up together and this is causing them to recieve an induced voltage of approx 19V, Sepperating the cables is not an ooption as they are all buried in the building fabric. Another problem we've noticed with LED dimming includes new lighting technology. In the case of non- led bulbs, this wouldn’t occur because they require a higher voltage, but as led bulbs are highly energy-efficient, even such a small source of electricity form the dimmer can cause these bulbs to light up dimly. Black light technology is a cinch for LED. If it is still on, you have some leaky wiring, which can be very dangerous. Current LED light sources and luminaires are very durable and normally last between 15,000 and 50,000 hours. If the bulb continues to glow well after being separated from the bulb holder, the problem is most probably with the bulb stocking up energy on its own.
