no but connector used in 110 rated have to be different in 220 rated system
------------------------
They are very much different. If you place a 110v rated fixture on a 220v circuit, all else being equal, you will double your current flow and odds are it isn't designed to carry twice the current. It will burn out.
On the other hand, if you place a 220v rated fixture on a 110v circuit, all else being equal, you will only draw half as many amps as it is designed for and likely won't get any light. It won't burn out, but it almost certainly won't work.
There are many fluorescent light fixtures that are rated for more than one voltage, however. They have internal mechanisms that allow you to connect them to different voltages and still work properly. But the fixture still has to be rated for the voltage that you connect to it.
The first answer above is correct in that cord and plug connections in the same installation (home, building, business) must be different for different voltages.

Do you have a diagram for converting 277 volt light to 110 volt?
It sounds like the fixture that you acquired was from an industrial site. 277 volts is the star point voltage of a 480 three phase system. You will have to change the ballast out to the proper voltage that you need. If you want to spend some money you can get a step up auto transformer to make the conversion but the cost would off set the cost of a new fixture many times.
How do you rewire a 400 watt metal halide shop light to run on 110?
400w is the power 110 is the voltage. Is your light using 110v already or 220v? Believe you are already running at 110 and u don't understand electrical terms. Perhaps you should call an electrician
Different types of voltage and current?
110 and 240
How many watts of lighting is required in a 15' x 10' room?
'Lighting', or the amount of light is not measured in watts. A 'watt' is a unit of power, measurement of current drawn. Most 100 watt/110 volt lamps initially produce 1690 lumens (a 'lumen' is the measure of the total "amount" of visible light emitted by a source). A 15 foot by 10 foot room is not very big, and one or two 100 watt incandescent lamps on a ceiling light fixture on a 120 volt service can light it adequately. I mention "110 volt" as in parts of the world with 220 mains these numbers change. As the voltage is doubled, the watts required would halve for the same amount of light. In other words, all other things being equal, a 50 watt 220 volt lamp should use the same amount of power, producing the same amount of light as a 100 watt 110 volt lamp.
How do you covert 277 light fixtures to 110 light fixtures?
You need to rewire to a lower voltage at panel or get a transformer that steps down 277 to 110 volts. Make sure wire is sized for new load as well as breaker.
