How much power does a 100 watt bulb consume?
So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).
Is a 100 watt bulb bright?
The wattage tells a buyer how much energy the bulb uses, not how bright is. For instance, a 100-watt light bulb is not necessarily brighter than a 40-watt light bulb. This is very relevant today as newer light bulbs use less energy, so wattage is not a reliable measure of a light bulb’s brightness.
