0.6 kW times 18 hours = 10.8 kWh.
To calculate the kilowatt hours (kWh) used by a 30 watt light bulb in 8 hours, we first convert the power to kilowatts: 30 watts = 0.03 kilowatts. Then, multiply this by the time in hours: 0.03 kW * 8 hours = 0.24 kWh. So, 0.24 kWh are used to light a 30 watt light bulb in 8 hours.
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
An LED light bulb can last up to 25,000-50,000 hours, depending on the quality of the bulb and usage. This makes them much more durable and long-lasting compared to traditional incandescent or CFL bulbs.
The time it takes for water to evaporate under a 75 watt light bulb can vary depending on factors such as the amount of water, humidity levels, and distance from the light bulb. Typically, it may take a few hours to a day for a small amount of water to evaporate under a 75 watt light bulb.
When the filament of a bulb becomes hot, it can react with the air around it, causing it to change size and / or shape, breaking the filament. Argon is unreactive, and so when this gas surrounds the filament, it prevents it from reacting, so preserving it for a longer period.

Convert the 100 watts to kilowatts. Calculate the total time in hours, and multiply by the number of kilowatts that the light bulb uses.
It is rumored that Edison's carbon filament light bulb, demonstrated in 1879, burned for over 40 hours. However, this was not the first light bulb ever created, as other inventors had developed similar technology prior to Edison.
