When troubleshooting a 120 volt light fixture with a volt meter and it reads 160 volts what could be wrong?

Check the volt meter. Less expensive meters go out of calibration very easily. This could lead to an over reading. If you know an electrician, ask to check his meter against yours for an accuracy reading. A digital meter is usually more accurate than that of an analogue meter with a moving needle. A moving needle meter has a screw slot adjustment so that the needle can be zeroed in to the left side of the meter where the scales all start at zero.
Now if you have established that your meter is not At Fault then you should call the electrical utility company and explain that you think their voltage is higher that it should be at your residence. A normal voltage from the electrical utility company should be in the the range of 110 to 120 volts. Using the top figure of 120 volt, even at 10% over, it should never exceed 132 volts.

How do you wire a 240 volt light fixture?
Does it have a name plate or instructions on how to wire it? the wire that you pulled black,red or red ,blue goes to one of the fixture leads and the other color to the remaining fixture lead. green to green for your grounding conductor. As always if you are unsure consult a qualified person in order to be safe!

You have an outside light that won't work but switch has power?
First and foremost make sure the light bulb is a good one. Try it in another fixture to make sure, even if it just came out of the box it was packed in. If you have checked the switch for power then you must have a tester. The power coming to the switch will most likely be on the top screw. Turn the switch on and see if you have voltage on the bottom screw. Check this voltage from the screws to the ground wire as the neutral will not be accessible in the back of the switch box. If there is voltage to the bottom screw then move on to the light fixture. Remove the outside light fixture and see if you get a voltage reading on the incoming hot (black ) wire. If there is voltage there then you have to see if the lamp holder is making continuity. If you have an ohm meter or a continuity meter remove the lamp fixture from the "hot" wire and the neutral connection and see if you get a reading across the fixtures black and white wire. This has to be tested with the bulb in the fixture. No continuity reading then there is trouble with the socket. Might be time to think about a new fixture.
Can you measure lighting?
You can measure light by:The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the power of light perceived by the human eye.orA light meter is a device used to measure the amount of light.You measure a lighting fixture with a ruler, too

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.
Why meter clocking need to be performed for any new piping installation?
To get an actual reading of fixture /appliance demand
What object could you use to measure the brightness of the bulb?
An item called a LUX meter is usually used for the determination of the brightness of a light bulb. It is generally a meter that measures the amount of incident white light.
Outside porch lamp has no box just two wires coming in black wires are tied and don't connect to fixture just the white wires what is going on here?
You would have to provide more info to be certain what your problem is. Typically a black and white wire would connect to the two wires on the light fixture. The fixture should also be controlled by a switch that "breaks" the black (Hot Wire) to turn off the fixture. If you have a volt meter you can see if there is 120Volts between the black and white wires with switch on. If there is a single white wire going to fixture (Neutral), where is the "black wires tied" to. Maybe one of the black wires has broken off the fixture.
Why might a scientist use a light meter?
Scientist use a light meter to show how light in shining on a surface !
What is a light meter used for?
If you mean a light meter that is used in a photographic studio, then it measures the light that hits the 'subject' from the studio lighting, the light meter then tells you what you need to set your camera to, for the correct exposure.
