Hi all, I just fitted a new ceiling light in our bedroom. The light is mounted on the ceiling in the middle of the room, with the wiring going through the ceiling to the wall mounted switch right outside the kitchen. I just changed out a fan for a light fixture and the light won't turn off. I think the switch live and permanent live have got mixed up. There may … Shut off power to the circuit before touching a bare metal light socket. By the way, are you sure it's real? Getting it fixed while everyone is still alive is liable to be "a good idea". In such case it will take some time to waste accumulated energy, like in that hand watch that glows at night. The light fixture then cools down, and after a few minutes it will come back on. I recently changed a bulb in a light fixture, but when I switch it off, instead of it turning off it just goes really dim? Update the question so it's on-topic for Electrical Engineering Stack Exchange. I watch the lights turn on and off and ceiling fan turn on and off … What is the policy on publishing work in academia that may have already been done (but not published) in industry/military? With the power shut off, check the wire connections on the switch to make sure they are all tight. Does the light seem to be at full brightness or dim when its lit, when the switch is apparently off The N in and N out should be the two together Sounds to me like you have the black switchline in with the black N out LED lamps keep glowing when dimmer is turned off, Help with fixing LED night light that won't turn off, Using only a rheostat on a LED ceiling panel light, Very low current (<10 microamps) darkness detector circuit that turns off in light.

Is that normal or I need to check it out by an electrician ? Most of the time, the LED bulbs on a ceiling work through two-way connections. Those Poorly done electrical wiring can also result in glowing led lights despite the switch being turned off either due to parallel cable installation or because the neutral conductor is switched. Single wall switch (to turn light on). Very little power, but still. There is no indicator light. I was always under the impression that no power would be supplied to a light fixture when the power switch is off. From my limited knowledge I would guess the lamp's circuit has some residual current which is not enough to light up the halogen bulbs, but makes the LED emit the dim light observed. In this case, you must change the cable from the switch to the light outlet from a 2-wire to a 3-wire cable. The original batten light also has the loop which was being used. If the switch is bad, you should replace it because you can't fix it. This means that the AC voltage on the hot wire can still slightly power the leds and/or the capacitors in the light bulb, leading to a few milli or micro amps of current to flow through ultra efficient leds, lighting them up. BTW-- I live in an old house without a ground wire at receptacles. But if you use equipment on the circuit where neutral and ground are connected (as happens even though it shouldn't) then such equipment will be "safe enough" on a properly connected circuit BUT lethally dangerous on this one. That being said, many white LEDs work by having an LED (usually UV) stimulate a phosphor to emit the white light. As per instructions on light fitting earth into earth, red beside brown marked L, black beside blue marked N and nothing in section marked LIVE LOOP. How many things can a person hold and use at one time? Shower does seem to respond to pull switch (irrespective of light) and working okay again now. When I turn on Main Switch of the house, I see the LED starts emitting very dim light ( have to look for a 3-4 second to perceive) even when LED's switch is off! 1 is red, 1 is black and the other has no plastic around it so i assume that is the earth. How can I quickly grab items from a chest to my inventory? I have recently purchased an IKEA LED bulb with G9 fittings, to replace a halogen one. Pretty easy i thought, but no, its permanently on and i cant turn it off at the switch. Reducing strobing of LED based household light bulbs, Replacing incandescent bulbs with LEDs, unexpected behavior. LED light bulbs flicker when switched off - where does the energy come from? But I didn't understand - switched to neutral. How do you take into account order in linear programming? I unplugged the 3 wires to the swith...LED stayed on. If I knock down this building, how many other buildings do I knock down as well? Whenever I shut the laptop down normally or in safe mode the screen will go black (as expected) but the power light will always remain on. We wired it identically to previous switch (where neon came on with switch or off as required) but now wonder if new switch had feeds opposite way. I would like the LEDs to light up only one at a time. The Phosphor is normally used to be give leds their white color through photo luminescent reaction, reacting to photons of a different wavelength, but it can glow in the dark without that. Main circuit breaker went off 10 days ago, but never then after. However once i let go of my finger the led light goes off already. If the switch is miswired, it's easy to rewire. I have found a strange behaviour. No additional energy is being consumed. The LED light glows continuously when off, or until I unscrew it from the ceiling fixture. How true is this observation concerning battle? hi, I've just fitted a new ceiling light in my kitchen but the light stays on no matter what way i flick the switch. It will not draw more current than it would with the halogen lamp, and all but the last cause are nothing to be concerned about. I would guess that your off-low-high switch has an indicator light so you can find it in the dark, so the LED lamp ends up in series with the indicator when the switch is 'off'. If the VP resigns, can the 25th Amendment still be invoked? In that case there is a possibility of some very low alternating current flowing via C10 to GND even if the switch is open. When make connecti … read more If the switch is old and has a loose toggle, replace it. If I turn the switch to off, then the light is completely off. You can get visible light from microamp-range currents. Some switches have a neon illumination to help find it in the dark; if so it will be connected ACROSS the open switch forming the leakage path mentioned above. I have a Honda Fit and just installed a LED light bulb in my dome light. Just a short buzz, really. Colleagues don't congratulate me or cheer me on when I do good work. Single wall switch (to turn light on). 3 wires coming from ceiling earth, black and red. But when you switch it off, some of the current remains in the circuit which is not enough to switch on the light or ceiling fan and hence it flickers the LED light for some time. I have found a strange behaviour.

I have problem with my CH whereby first thing in the morning when the heating comes on it doesn't switch off when the thermostat temp setting is reached and continues to heat the house. The bulb is installed in a lamp with 3 other halogen G9s in a 3 + 1 configuration with a 3-state switch. "up" lights up all four bulbs, "down" lights up only the socket where the LED is. I wanted to make an LED come on when you press a button and stay on, then once you press the button again it goes off and stays off until you press the button again. However, as soon as I connect the ground wire from the rocker switch to ground, the led light comes on and stays on regardless if the switch is in the on or off position. The light is on the ceiling and has four halogen bulbs. It is no longer happening, so it seems that this lamp is wired like circuit #2. The light and switch (single pole) have been in operation for 15 years. Phosphor emits light at total darkness, but it is dangerous because of radiation, radio active radiation, so this new LED bulbs may contain a small amount of chemicals like phosphor or something like to improve the light output of the bulbs, that's why they gloing even after shut them down for quiet some time. LED lamps are different though and in some cases that current may just be enough to actuate the circuitry in your lamp and cause it to glow, albeit dimly when the light switch is off. One way should result in completely off leds. When the lamp's switch is in the off position, the LED bulb still emits a very dim light, whereas the halogen ones do not. LED bulb still emits light when turned off, Podcast 302: Programming in PowerPoint can teach you a few things, LED lights with a dim light in open circuit. I took a hint from a previous comment and flicked the plug 180 degrees on the wall outlet. When make connecti … read more Dimmer circuit that has an internal snubber and is not switched off entirely. LED lamps are different though and in some cases that current may just be enough to actuate the circuitry in your lamp and cause it to glow, albeit dimly when the light switch is off. Why was there a "point of no return" in the Chernobyl series that ended in the meltdown? But another of the same fixture is next to it, that one goes off … I have just tried a switch from another light with the wiring as I originally posted and it works to turn on and off the light so it must be the switch that needs replaced ... is the new switch compatible with LED … Ceiling light stays on when switch is off - australia? A voltage-carrying conductor might sometimes induce its 99 Capacitor or RC snubber across switch to avoid EMI when switch is flicked (not seen often in North America, but might be a possibility in Europe). When you say it continues to glow, does it glow continuously, or just for seconds/minutes? Still I will let it checked very soon. At present the lights stay on but the switch doesn't turn it on or off. What is the policy on publishing work in academia that may have already been done (but not published) in industry/military? The ceiling lights/ fan was not remote control only wall control. Decided to replace them with Philips Dimmable Blunt Tip B13 LED Lights. I once had a similar thing happening for a lamp, and it turned out that turning the wall plug by 180° (thus switching phase and neutral) "fixed" it. Is the light switch a normal on-off type or is there any kind of electronic switching such as a remote or dimmer? And the phosphors used in LEDs don't contain radioactive elements, because their purpose is not to glow on their own, but to convert UV light into white visible light. Short of rewiring your lighting, one solution is to stick something in the circuit to mop up this unwanted voltage.
