New ceiling fixture goes on as soon as power is back even though switch is off?

You switched the power and switch wires. There should be two sets of wires in the ceiling box. 2 black, 2 white, 2 bare. Two groups of three. The white wire going to the light is the incoming wire. The black one in that group is the power coming in. Take that black wire and connect it to the other black wire. The second black wire goes to the switch. The power comes back to the light on the white wire of that set. Connect that white wire to the black wire in the fixture. The switch should work now. That is if everyone wired the house the way it is supposed to be.

This could be due to a wiring issue where the fixture is connected directly to power instead of being controlled by the switch. Check the wiring to ensure it is correctly connected to the switch. If the issue persists, consult a professional electrician to investigate and fix the problem.

What would cause a ceiling fan's lights and fan to stop working while the small LED on the wall switch still lights when it is switched on?
That led is only showing that there is power to the switch and/or the light and fan fixture. You would have to check the power at the fixture to determine if it is actually in the switched feed or the fan/light assembly.
Why does dimmer switch cause ceiling light to make noise?
Dimmer switches control the amount of electricity flowing to the light fixture by rapidly turning the power on and off. This rapid cycling can cause the light fixture to vibrate or emit a buzzing sound, especially if the light fixture is not compatible with the dimmer switch. Upgrading to a dimmer switch designed for the specific type of light fixture can help reduce or eliminate the noise.
What if your ceiling light does not work although there is power to the live wire?
If there is power to the live wire but the ceiling light is still not working, the issue may lie with a faulty light bulb, a bad connection between the wire and the fixture, or a defective switch. Try replacing the bulb first, then check the wiring connections and the switch to ensure they are functioning properly. If the problem persists, it may require further inspection by a professional electrician.
Where does the switched live go in a ceiling light?
The switched live wire in a ceiling light typically connects to the live terminal of the light fixture. This wire carries the electrical current and is controlled by the light switch to turn the light on and off. Make sure to turn off the power before making any electrical connections.
What is a keyless light fixture?
A keyless light fixture is a type of light fixture that does not have a switch or socket that can accommodate a light bulb. Instead, it is typically wired directly to a power source and requires a light bulb with a built-in switch for operation.

Installing A Ceiling Light?
Installing a Ceiling LightInstalling A Ceiling LightReplacing ceiling lights is sometimes a required task when you decide remodel a room or the light fixture has worn out with age. Installing a new ceiling light is a simple task that can be done by most homeowners without any outside help.The first thing to do before installing any light in your ceiling is to turn off the power at the circuit breaker. Since you will be working with electrical wiring, you do not want to take the chance of being shocked or electrocuted. After the power is turned off, unscrew the light bulb from the existing fixture and use a screwdriver take out the screws holding the fixture in place and connecting the wires to the fixture.When the fixture is off, attach a mounting plate to the ceiling light outlet box. Then attach the wires to the new ceiling light fixture. Connect the copper wires together and like colored wires together with wire nuts so that the fixture is properly grounded.Attach the base of the new fixture over the outlet box and tighten it up with screws. Once this is finished, screw the light bulb back into place and put a glass bowl over the bulb to cover it. Use bolts on sides of the fixture to secure the glass bowl in place.Once the fixture is securely in place, return to the circuit breaker. Turn back on the power and test out the light to ensure everything is installed correctly.
What wattage does a 3-way light switch use in a single switch outlet?
A 3-way light switch itself does not consume any power as it is a mechanical device that controls the flow of electricity to the light fixture. The power consumed by the light fixture will depend on the bulbs used and their wattage.
How do you replace dining room light fixture?
Turn off the power to the fixture at the circuit breaker. Remove the old fixture by unscrewing and disconnecting wires. Install the new fixture by connecting the wires following the manufacturer's instructions. Secure the new fixture in place and turn the power back on to test it.
How do you wire a series of recessed lights to a single switch when the power goes to the lights first?
To wire a series of recessed lights to a single switch when power goes to the lights first, connect the black wire from the power source to the black wire of the first light, then connect a jumper wire from the white wire of the first light to the white wire of the next light, and so on for each additional light in the series. Finally, connect all of the grounds together and connect the switch to the black wire of the first light.
What would cause loss of power to the wires in the ceiling for a light fixture if the breaker is not tripped?
There could be a loose connection at the fixture, switch, or in the wiring causing a loss of power. It could also be due to a defective fixture, a damaged wire, or a faulty breaker. Additionally, there may be an issue with the electrical circuit or a problem with the main electrical panel.
Have ceiling fixture with a yellow wire and a combination wire of white and grey and fixture has black and white wires do you attached the black to the yellow?
No, the black wire from the ceiling fixture should be connected to the combination wire of white and grey. The white wire from the ceiling fixture should be connected to the yellow wire. Always follow the manufacturer's instructions and turn off power before making any electrical connections.
How many line conductors are installed between the switch and light fixture?
One. A typical "two way" ON-OFF light switch is a Single Pole Single Throw (SPST) switch with two terminals. It is wired in series with the fixture: that is, the power circuit is routed from the breaker to one side of the switch. The other side of the switch is connected to the "phase" or "power" terminal of the fixture. In a 115VAC single phase circuit, the other terminal of the fixture is connected to neutral. A "three way" switch circuit consists of two switches in different locations, each of which is a Single Pole Double Throw (SPDT) switch with three terminals. A typical use would have one switch at the top and the other at the bottom of a set of stairs. For the sake of clarity, we can label the "common" terminal on a SPDT switch the "C" terminal. This terminal is internally connected to one of the other two terminals, call them "A" and "B", depending of the position of the switch. A three way switch is connected with the circuit breaker connected to the "C" terminal on either switch. Conductors connect the "A" terminal on one switch the the "A" terminal on the other switch and the "B" terminal on one switch the the "B" terminal on the other switch. The remaining "C" terminal is connected to the "phase" or "power" terminal of the fixture. The other terminal of the fixture is connected to neutral. Note that, in either case, there is no neutral wire connected to the switch. Ground conductors do connect to the chassis of the switch box and the fixture, but they do not carry current and do not affect the operation of the circuit.
