LED lights have received widespread use because they are more than 75% more energy efficient than traditional lamps, and are gradually becoming the preferred choice of energy-conscious consumers. So is the cost of running LED lights for 24 hours really low? In this article we will calculate the running cost of LED and analyze why LED lights are so energy efficient.
How to calculate the running cost of LED lights for 24 hours?
To calculate the cost of running LED lights for 24 hours, the first choice is to consider two factors: the wattage of the LED fixture and the cost per kilowatt hour.
In the United States, the average cost of electricity per kilowatt hour is between $0.10 and $0.20 (depending on your local energy provider).
Let's take a 30-watt LED wall sconce as an example, with an electricity cost of $0.15 per kilowatt hour, based on the cost formula below:
Cost = (Wattage x Hours of Use ÷ 1000) x Electricity Charge
A small 30 watt wall sconce running for 24 hours: cost = (30W x 24 hours ÷ 1000) x $0.15 = $0.108
It only costs 10.8 cents per 24 hours to keep a small 30-watt wall sconce running. JC-LGL's small wall sconce also has a Dusk to Dawn Photocell feature that automatically shuts off the light during the day, which can more accurately reduce unnecessary running time, further reducing running costs and saving even more energy.
Why are LED lights cheaper?
LED has such a big cost advantage mainly because of these factors below:
- High energy efficiency: The most prominent advantage of LED lights is that they have very high energy efficiency. Compared with traditional incandescent or fluorescent lamps, LEDs are able to convert a higher percentage of electrical energy into light, which makes LED lights produce the same amount of light as incandescent or fluorescent lamps while consuming less power, greatly reducing energy consumption.
- Long service life: LED lights usually have a more robust housing than traditional lamps, as well as better heat dissipation, all of which make LED lights more durable. The long enough service life also reduces the frequency of replacing lamps, thus further reducing expenses.
- Low maintenance costs: Because of the longer service life of LED lights, so can greatly reduce the frequency of replacement lamps, which not only saves the cost of new lamps and lanterns, but also reduces the maintenance costs. Especially for some of the difficulty and cost of maintenance are higher commercial premises, the use of LED lights can save a lot of money.
