The cost of running a LED light bulb for 24 hours depends on the bulb's wattage and your local electricity rate. For example, if you have a 10-watt LED bulb and the electricity rate is $0.12 per kilowatt-hour, running the bulb for 24 hours would cost approximately 2.88 cents (0.01 kW * 24 hours * $0.12/kWh). To get an accurate estimate, multiply the bulb's wattage by the hours used, divide by 1,000 to convert to kilowatts, and then multiply by your local electricity rate.
