Ok, light bulbs I get come in 20 or 40 or 60 watts. But if there was a 1,000 watt light bulb and it was left on for 1 hour would it use a kilowatt-hour? Also correct me if I’m wrong; kilowatt is 1,000 watts, megawatt is 1,000,000 watts, and a gigawatt is a billion watts. If both the things I’ve said are true then would a 1,000,000 watt light bulb left on for an hour use a megawatt-hour? Any other information you think I should know about this would be appreciated.

I am talking about the kind that store for ages and then you break them to make them light up. They last for about 12 hours. I am sure its some sort of reaction or phosporescence or something.
