Lighting is an essential part of our daily lives.
LEDs have emerged as a leading choice for illuminating and enhancing our living and workspaces, including homes, offices, and public areas. These cutting-edge lighting solutions provide the ability to clearly see and perform tasks with precision and efficiency.
LED stands for Light Emitting Diode, and these lights have rapidly become popular due to their energy efficiency, long lifespan, and low heat output.
Despite their increasing popularity, there remains some uncertainty regarding the electricity consumption of LEDs.
In this blog, we will shed some light on this new technology.
Power Consumption
LEDs are known for their energy efficiency. They convert most of the electricity they use into light, rather than heat, and this makes them much more efficient than traditional incandescent bulbs.
The amount of electricity used by LEDs is measured in watts per hour, or kilowatt-hours (kWh).
A kilowatt-hour is equal to 1,000 watts of electricity used for one hour.
LED vs. Traditional Lights
Traditional incandescent lights, which have been used for more than a century, use a lot of electricity. For example, a typical 60-watt incandescent bulb uses 60 watts of electricity per hour.
In comparison, an LED light bulb that produces the same amount of light as the 60-watt incandescent bulb uses only 9 watts of electricity per hour. This means that LED light bulbs use significantly less electricity than traditional incandescent bulbs.
Fluorescent bulbs, on the other hand, are more energy-efficient than incandescent bulbs but still use more electricity than LED bulbs.
A typical 18-watt fluorescent bulb uses 18 watts of electricity per hour. In comparison, an LED light bulb that produces the same amount of light uses only 5 watts of electricity per hour.
How LongDo LEDs Last?
LEDs are known for their extended lifespan, as they last up to 25 times longer than traditional incandescent bulbs and up to 3 times longer than fluorescent bulbs.
This means that LEDsneed to be replaced much less frequently, reducing their overall environmental impact.
What About LED Strip Lights?
LED strip lighting is a popular option for homes and businesses, and the most important factor depends on the length of the strip and the number of LEDs in the strip.
On average, a 16-foot LED strip light uses around 36 watts of electricity per hour.
If you use a 16-foot LED strip for 6 hours a day, you will use 216 watts of electricity per day, or 0.216 kWh.Over a year, this would add up to 78.84 kWh.
The Cost of LED's Power Consumption
Electricity cost varies, depending on where you live and your electricity provider.
In the United States, the average cost of electricity is around 13 cents per kilowatt-hour.
This means that using a 60-watt incandescent bulb for 6 hours a day for a year would cost you almost $50 in electricity.
In comparison, using an LED light bulb that produces the same amount of light for 6 hours a day for a year would only cost around $7.
If you're worried about the cost or want to be even more environmentally friendly, you can also consider outdoor solar LEDs.
How to Calculate
To calculate the electricity usage of LED lighting, you can use the following formula:
Electricity Usage (kWh) = Power (Watts) x Time (Hours) / 1000
For example, if you have a 9-watt LED that you use for 6 hours a day, the calculation would be:
Electricity Usage (kWh) = 9 x 6 / 1000 = 0.054 kWh
Advantages of LEDs
There are several advantages to using LEDs:
Energy Efficiency: LEDs are highly energy-efficient, converting most of the electricity they use into light rather than heat. Because of their efficiency, LEDs are used in a range of applications. A few examples include entertainment and stage lighting, cars, and medical applications. LEDs are the go-to light sources for Christmas trees and other Christmas season decorations, as they produce less heat and are safer to use for extended periods.
Energy Savings: Since LEDs use much less electricity while still being able to produce the light you need, these lights also save you money in the long run. Compared to conventional incandescent lighting or fluorescent lighting, they will use a lot less electricity.
Long Lifespan: LEDs boast an impressive lifespan that far surpasses traditional incandescent bulbs by up to 25 times, and fluorescent bulbs by up to 3 times.
Low-heat Output: LEDs produce very little heat, making them safer to use and they reduce the load on cooling systems.
Durability: LEDs are more durable than traditional bulbs, making them less likely to break or fail. This durability is due to its use of a sophisticated diode and semiconductor, as opposed to the heated filament in typical light bulbs. These bulbs burn hotter and burn out the filament, which eventually breaks the circuit.
