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.
'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.
France uses 220-240 volts for their electrical system.
Hot, neutral and ground.
your house has 220 you must use a 2 pole breaker. your wiring will change ,not a do it your selfer call someone
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
No. The bulb will burn out.
Only use 110-120 volt appliances on a 110 volt socket.
Typically they are either 220V or 110 volts not both. Plugging a 11o volt blanket to a 220 volt line has a huge risk of fire.
NO
Yes
you don't. you just take and use 120 volts from the 220. At least that's what I'd do.
Although it would be electrically safe, you probably don't want to do this, as it would give off very little light, far less than 1/2 of the rated amount of light.
no
Yes - usually house voltage varies from 110 to 120 volts.
115 Volt and a 110 Volt can be treated as the same thing. The electrical voltage supplied from your electric company is not exact and can be 120 Volt + or - 10%.
No adapter is needed, 110 and 115 volt are interchangeable.
No, the applied 110 volt is too high for a 3 volt appliance. The appliance would burn out right away.
