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?!

  1. There's a low power bulb In my room. That does the same. In pitch black it's still glowing damn. I was scared when I got to know

  2. both bulbs are probably from china tbf, that aside wouldnt you want the bulb that still glows and tells you that even though you switched it off there is still a current in your system? Also not really the bulb's fault, more down to shit wiring and the other bulb is not really fixing the issue just covering up the symptoms.

  3. All my G9 LEDs do this, my landing light fitting has 3 G9 bulbs and the only way to get it to fully switch off without permanently glowing is to replace one of them with a normal halogen bulb. Wierd…

  4. The analogy with the syringe has a bit of an incorrect statement, which also applies to electricity. You CAN overcome the resistance with enough pressure. In the case of electricity this results in an arc as there is sufficient voltage to overcome the resistance of the less conductive medium of air to allow the current to flow to the other end. I always wondered about what those electrons that can't complete the circuit do, and now I know they are sloshing back and forth like water hammer due to AC.

  5. ? Remove grounding wire … U can see this in all bulbs ? **Shock will be inevitable if you remove the grounding wire ?

  6. So I wonder what would happen if this bulb was attached to the live? Following electron flow would mean that electric is still attached to the bulb if broken but with the live wire it would be detached… In theory anyway.

  7. this is mutual inductance hahaha circuit was being fed voltage from the receptacle and not the "capacitor" you made. more like an inductor.

  8. I get scared when he opens his eyes completely just as if they are going to drop on the floor just now xD ?

  9. He is saying you should not operate with open wires and 2 minutes afterwards he is playing with a jab full of water in front of the open circuit

  10. Interesting. But…My eyes were so fixated on your hands getting closer and closer to the live break in the wire as you were explaining how the accidental capacitor was created! ??

  11. So wrong. It has nothing to do with capacitance. It's a bad circuit in the bulb. The bios diode is to small and the voltage is leaking through.

    if the wire was ever holding charge your analog bulbs would stay on after you turned them off at least for a split second
    2
    leds are diodes them selves of the light emitting variety. Therefore they are DC. That means there 2 main things you can use a transformer or a rectifier. Well that's where in the circuit theirs an issue.
    3.
    Where is your tester. WTF .
    4. How much do you know about electrictonics, you are jumping into a complex problem that takes a little more explanation. Like a capacitor holds a certain amount of electrons than can't hold any more. A wire or a conductor allows for the free flow of electrons. The capacitors layers are to allow each plate to hold its maximum amount of electrictrons in the holes of the doped (germanium I believe) and the silicon insulation is to keep the electrons from escaping. But I'm not saying wire doesn't have any capacitance its just so neglectable it's like a the level of free flowing electrons in the air.
    5 .
    Please watch a video or two on how the different electronic components work before you misinform.

  12. I feel like I should have gone to BigClive to learn about the chinese bulb.

  13. SCR's and Triacs used in light dimmers along with a noise filter do the same. To make the bulb go out, a dummy load has to be added in parallel with the bulb. Use this with some stage lighting so the lights don't flicker when off.

  14. I bought a cheap LED R7S off eBay and had exactly this issue. I didn’t test it forever but would stay on overnight even when switched off. Freaked us out.

  15. The voicebocer goes through the flexolead into the the extra low microvoltile receper colectimost , slightly umbrifoil about 16 ohmers where a mind boggily combinode of two steely belties clatter clatter causing thus . Horendous expensifold but all clear now.

  16. in AC the current goes out and enters by its two poles and this lamp can recover the manganese current and gives to the return because it is a led diode and the magnet is attracting the electrons of the copper which seeks other electrons which come by the one foot of the lamp.
