These LED bulbs will continue to draw power from the mains indefinitely even once they're switched off and the circuit is broken. But how?!

    I'd say the wire is harvesting energy from the air, from radio waves, magnetism etc. just like you can do it with a wire put into ground. Otherwise the charge would be consumed. It doesnt make sense to me that you generate photons without any source

    here is why, i can proof it ,, the designer forget to put a pulldown resistor in that damn bulb,

    I've had this exact problem at a customers house. They were glowing at night. I solved the problem by connecting a tiny power supply parallel to the bulb.

    Your explanation alone should tell you that what you said doesn't explain it unless you are talking about a BIFILAR COIL! SCHOOL TEACHES WHAT TO THINK NOT HOW TO! Memory doesn't translate to intelligence! Caution school can make you an expensive idiot! Study TESLA NOT EDISON!

    You should put a meter on it to prove you are leaking some voltage from the source and not coming from the AETHER! A capacitor would eventually go to zero if source is OFF! So that means it is getting voltage from the AETHER not from you house! The copper windings(mass)are picking up voltage moving through the AETHER in the presence of a magnet(earth)as it does with a generator(copper windings) spins in the presence of the magnets(drum) of generator! This is why EDISON is an idiot and needed TESLA to solve his problems! And then not pay TESLA! EDISON IS A FRAUD AND A CROOK!

    There's probably a bleed resistor in the ones that go out when you turn it off. Just like on any capacitor setup. Thanks for sharing. Fascinating.

    OK at the 7 minute mark I stopped watching and am running out to get some of these way cool chineez lights that work with NO electric currant running thru them, that means FREE LIGHTING in my house. When the electric companys hear of this their buddie 'The Government' will outlaw these lights and demand we continue with these pathetic pig tail bulbs with poison gas inside them! guess I will buy a shit load of them chineez lights!

    It’s called a tank circuit. The coil of wire acts as an inductor & temporarily stores energy between the anode of the bulb & the coil. The same principle is what makes a Tesla Coil oscillate.

    The US LED had a transformer on it which takes all current and makes it another current; or, as explained, it equalizes the residual current effectively making that charge null.

    The collapsing magnetic field of a coil is the principle of operation for the ignition coils on gasoline engines. Even drag racing engines still use "Magnetos", a coil that produces huge current to fire the spark plugs that give those behemoths in excess of several thousand horsepower.... Coils are awesome... just ask the speakers you're listening to the audio of this video!

    There's totally nothing wrong with the bulb at all... the reason that the bulb lights up is that there is current flowing through it. Remember LED will light up with a very small current of just a few milliamps, unlike filament bulbs that require much larger currents such that it can generate sufficient heat before lighting up. I would recommend that you get your house wiring checked immediately before someone gets killed.

    this could be caused by a shared neutral or a loaded or a broken neutral so get your metre out and check both sides against Earth...very common problem in the UK if you have this problem get it checked.. all are very dangerous and can kill ...if the bulb lights when you touch it you are the ground call for an electrician not a DIY job

    its a cool effect for sure, at first i thought it was going to be some induction thing because of the coil of wire.

    that is a inductance has the same effects that a capacitor , more or less, is not quite the same but stores energy like one

    It’s acting like an inductor not a capacitor. The coil of wire is opposing a change in current. The loop of wire has a magnetic field around it. When current flow is interrupted, the collapsing field generates current.
