## 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.
