Yes; you need to know how long the light bulb is on.
<h3>How much electricity does a light bulb use?</h3>
Because of this, lower wattage bulbs are sometimes referred to as "equivalent to 60W"; nevertheless, what is equal is brightness, not energy consumption.
Converting wattage to kilowatts is the best way to determine how much energy your lightbulb consumes. Thus, 0.1 kW would be needed per hour for a 100W light bulb.
Incandescent (up to 100W) and halogen (up to 120W) light bulbs with higher energy consumption are being phased out. You may get ornamental exposed carbon filament light bulbs, which are normally 40–60W, if you still have any of them operating in your house.
