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.

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.
What if your ceiling light does not work although there is power to the live wire?
Is this a fluorescent fixture? Most fluorescents will not start if the fixture is not grounded. Make sure the fixture has the branch circuit ground wire properly connected.
How do you wire a series of recessed lights to a single switch when the power goes to the lights first?
If you already know how to put one fixture on a 3-way, just connect white-to-white and black-to-black from one light to the next. If you're changing from a single switch to the 3-way, the exact wiring will depend on whether the power comes from the breaker box to the switch or the existing fixture. I'll assume you're starting from scratch or have the power going to the fixture. You need #15 two-wire with ground and #15 three-wire with ground romex. Run two-wire from the breaker box to the first light fixture. Pull a another two-wire from this box to switch A and a three-wire between the switches. String two-wire from the first light to the second, second to third, etc. In the first box, connect white from source to the white fixture wire and the white going to the second box; black from source to the black to switch A; and the black fixture wire to both the white to switch A and the black to the next fixture. At each of the other 5 fixtures, connect all white to white and black to black (three pair in each box except the last one). At switch A, connect the white from the fixture to the common (center) connector and the black directly to the black going to switch B. The red and white wires going to switch B are connected to the two outside connectors of switch A. At switch B, the black goes to the common connector and the red and white to the outside connectors. At each box, connect all the bare wires (second ground) to each other and to the fixture or box. Now turn the power back on. If all the connectors are tight, power should follow the black wires from source past the fixture and switch A to switch B. From there it will go through one or the other of the travellers and, if switch A is in the same position as B, up the white switch leg to the fixtures, turn on all the lights and go back to ground.
What are the four features required to construct a working simple circuit?
power source, wire, switch, end fixture. Simplest circuit would be a power source and a heating element. No wire or switch needed.
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.

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.

How much power does a fluorescent fixture use with no tubes installed For example a switched on 8' fixture with a single tube with an old ballast.?
Depends if ballast is in fixture and switch is on. Several watts if new ballast and perhaps 15 watts for old ballasts....
How do you replace dining room light fixture?
If you don't know how to install light fixture, I don't recommend that you do it by yourself. The installation theory is actually very simple - all you need to do is attach fixture on the ceiling (or any other place) and then connect the electrical wires (usually there are two of them). After that it's good to put the light cover over the fixture to improve the appearance.
What would cause loss of power to the wires in the ceiling for a light fixture if the breaker is not tripped?
Bad ground connection. Corrosion on wire. Broken or cracked wire. Bad Switch. Mouse chewed through wire. just a guess but it may be faulty wiring in the fixture itself you can try to figure it out first try to problem solve it.did you replace an older one?is it a new fixture?did it work before or after you replaced it?andis it a fairly old one?you can replace it as a last resort.
How To Install A Lighting Fixture Onto Your Ceiling Fan?
There are many beautiful lighting fixtures available that can be installed onto a ceiling fan. These lighting fixtures can create a special atmosphere are provide great lighting options within a room. Installing lighting fixtures are very easy to complete yourself on a ceiling fan that is already in place. Here is a guide to help you complete this project in your home. Step 1. Gather all of the products, tools and supplies you will need to complete your lighting fixture installation. For this project you will need a screwdriver, a pair of pliers, wire insulation stripper, your chosen light fixture kit and a step ladder. Step 2. Before you begin with the installation process, you will need to turn off the power to the switch that controls your ceiling fan at the breaker box. Step 3. Remove all glass fixtures that come with the light fixture for your ceiling fan. In the center of your light fixture you will find a tube with a nut and washers. Both the nut and washers should be removed and set aside for later. Remove the center of the canopy and place it on the top of your ceiling fan lighting fixture where the tube is positioned. The canopy with thread downward or slide down over the tubing. Using the washers and nuts that you set aside, tight the canopy onto the lighting fixture. Make sure that this is tight but do not over tighten. Pass the black and white wire that is on your light fixture through the hollow center tube. Use a gentle pull to accomplish this so that the wires do not break. You will be able to see the inside wiring of the ceiling fan. Pull the black and white wires that are used for lighting fixture installation down. If these wires are insulated at the end, remove the insulation cap. If no insulation cap is present, strip about one half inches of the insulation off of each wire. Connect the white wire on the ceiling fan with the white wire on the lighting fixture. Connect the black wire on the ceiling fan with the black wire on the lighting fixture. Finish this by twisting the exposed wires and cap each set of wires. Tuck these wires back into the ceiling fan without breaking them. Replace the screws and tighten them securely without over tightening. Step 4. Place the glass covers that come with the light fixture in place. Insert all necessary light bulbs as needed. Restore the power supply to the ceiling fan. If necessary, attach a pull cord for your lighting fixture.
What is One everyday use of a series circuit?
The average light fixture is likely in series with the light switch, and the utility power grid.
Why don't I get power at ceiling fan when I have power at light switch?
Check the wire. It must have been broken in between
