How do you calculate power consumption of a light bulb?
To find the kilowatt-hours your light bulb consumes per month, multiply the kilowatt use by the number of hours it’s on each month. Example 1: The incandescent bulb uses 0.06 kW of power and is on for 180 hours a month. Its energy usage is (0.06 kW * 180 hours/month) = 10.8 kilowatt-hours per month.
How do you calculate light bulb consumption?
To find the total wattage of a fixture, add the wattage of each light bulb together.
- fixture watts = bulb watts × bulb quantity.
- kWh = Power(W) × Time(hrs) ÷ 1,000.
- monthly kWh = kWh per day × 30.
- price = kWh × cost per kWh.
