How much does it cost to run a 60 watt LED bulb for a year?
If you used a bulb for just two hours a day and paid the national average of 11.5 cents per kilowatt hour, a single 12-watt LED will cost you about $1 per year. Comparable CFLs that consume about 14 watts come to $1.17 per year and about $5 a year for 60-watt incandescents in that scenario.
How much does it cost to run a 60 watt LED light bulb for 24 hours?
Let’s say you have a 60-watt incandescent lightbulb and you are paying 12 cents per kWh of energy. Leaving the bulb on the whole day will therefore cost you: 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = approximately 20 cents in one day.
How much does it cost to run a 60w bulb for one hour?
A 60 watt lightbulb left switched on for one hour is equal to 0.06 kWh (divide 60 watts by 1000 to get the kW) – so you multiply 0.06 kWh by your provider’s kWh price, to get the cost.
How much energy do LED lights use?
Without taking into account the cost of the fixtures, an LED bulb (18 watts) can cost as much as 950, a CFL of 23 watts 200, a fluorescent tube of 36 watt around 85 (there are also LED versions that cost much more, at least 500), while a 100 watt incandescent bulb costs around 12.
How much does it cost to run a 100 watt LED bulb?
We will also assume that a kWh of energy costs 15 cents. Incandescent: A 100-watt, classic light bulb running for a full year would use up 876 kWh of energy. This means a full year of running one incandescent bulb would cost $131.40.
How much does 100 watts per hour cost?
Watts X Time / 1000 X Cost per KWH = Total cost. Let’s use a regular 100 watt light bulb for example, lit continuously for one year (8760 hrs.), at a cost of 12 cents per KWH. 100 watts times 8760 hrs. = 876,000 divided by 1000 (converts to KWH) = 876 KWH times 12 cents = $105.12.
