Did you know that the majority of energy used by LEDs is for producing light, not for heating or cooling like with traditional incandescent bulbs? Did you also know that LED lamps can last up to 25 times longer than standard lights? If so, you probably understand why more and more people are switching to LEDs. They’re cheaper in the long run, they use less energy, they don’t heat up and they last longer. But do LEDs use a lot of electricity? The answer is yes – but only if you don’t compare apples to apples when it comes to cost and performance. Let’s take a closer look at how much energy LED lighting uses and why.
Do Led Lights Use A Lot Of Electricity?
It all depends on the type of light you are using, and how you are using it. LED lights are very efficient and use much less electricity than conventional bulbs. However, the amount of electricity used varies widely depending on a variety of factors, such as the brightness setting and the distance from the bulb. It is difficult to provide an accurate estimate of electricity use for LED lights, but it is generally 20 to 80 percent less than that of traditional light bulbs.
How Much Electricity Do Led Lights Use?
LED lights are more efficient than incandescent bulbs.
Because LED lights use less energy than incandescent bulbs, they use less electricity overall. According to the U.S. Energy Information Administration, LEDs use 30% less energy than standard incandescent bulbs and 10% less than CFLs (compact fluorescent lamps).
LED lights use a lot of energy for producing light
LEDs produce light using semiconductors that must be energized by a voltage that is much higher than that required to power an incandescent bulb. This means that in order for LEDs to work, you need to provide a lot of power – which is why they are so expensive and why they typically generate so much heat as well.
LED lights cost more upfront and last longer
Because LEDs require so much energy, it’s not uncommon for them to cost more upfront or last longer than traditional lighting options (like CFLs or halogens). This can be a big deal when you’re spending thousands of dollars on lighting because it can take months or years before you start seeing the savings from your new lamp(s). For example, if you replace all your 100-watt halogen bulbs with 40-watt LEDs and then turn off the light in your kitchen until morning, it will only save about $0.20 per day in electricity costs – but it will save you $16 every year! The math just doesn’t add up, but that doesn’t mean the savings aren’t there.
LEDs have a relatively short lifespan
While LED lights can last for years, their lifespan is much shorter than that of incandescent bulbs (5,000 to 8,000 hours) or CFLs (20,000 to 50,000 hours). In fact, according to the U.S. Department of Energy, LEDs can only last about 25 times longer than incandescents before they fail. For this reason alone – and because they typically cost a lot more upfront – LEDs are not an ideal choice for people who want to lower their energy usage and save money in the long run!
Comparing The Cost Of Led Lighting To Traditional Bulbs
- Traditional Incandescent Bulbs
These are the most common type of lighting in homes across the country. They are cheap to purchase, but they use a lot of energy and they’re inefficient. The majority of the electricity used by traditional bulbs is for producing light rather than heating or cooling.
- LED Bulbs
LED bulbs are more efficient than traditional incandescent bulbs and they use less energy. But they cost more upfront. And while they don’t heat up, their lifespan is shorter than that of standard incandescent bulbs, which makes them more expensive over time.
- CFL Bulbs
CFLs (compact fluorescent lamps) are a hybrid between LED and traditional bulbs in terms of efficiency and price – but not longevity or life-cycle costs LED lights do not heat up as much as traditional incandescent lights do, but their lifespan is shorter than that of standard incandescent lightbulbs – especially if you use CFLs with electronic ballast (as opposed to using them with a dimmer switch). In fact, CFLs only last about 1,000 hours on average compared to about 20,000 hours for LED lights. They also cost more upfront because you have to buy a special kind of bulb that can be used in your ceiling fixture – whereas LED lights come in both screw-in and non-screw-in varieties (e.g., lamp heads). So while LEDs may be more expensive than standard incandescent bulbs, they are also more efficient in terms of energy usage and life-cycle costs.
- Compact Fluorescent Lamps (CFLs)
Compact fluorescent lamps (CFLs) are a hybrid between LED and traditional bulbs in terms of efficiency and price – but not longevity or life-cycle costs LED lights do not heat up as much as traditional incandescent lights do, but their lifespan is shorter than that of standard incandescent lightbulbs – especially if you use CFLs with electronic ballast (as opposed to using them with a dimmer switch). In fact, CFLs only last about 1,000 hours on average compared to about 20,000 hours for LED lights. They also cost more upfront because you have to buy a special kind of bulb that can be used in your ceiling fixture – whereas LED lights come in both screw-in and non-screw-in varieties (e.g., lamp heads). So while LEDs may be more expensive than standard incandescent bulbs, they are also more efficient in terms of energy usage and life-cycle costs.
5 Cons To Using Led Light
1. LED lights use a lot of energy
LED lights use a lot of energy. But that’s not the whole story. Let’s compare LED light and incandescent light bulbs to find out how much electricity they use when compared to each other. For example, a 100-watt incandescent light bulb uses 10W of energy. It takes 12W of electricity to produce 1W of light and the remaining 88W are spent on heat, cooling, and other functions. The same 100-watt incandescent light bulb uses about $0.08 per hour for power, or about $0.33 per hour over its operating time (assuming it’s on for 8 hours). Compare this to an LED light bulb that costs about $0.30 each and lasts up to 25 times longer than an incandescent bulb. So it costs less than four cents per hour (or less than $0.03 per hour) in electricity for the LED lamp when compared with the cost of operating an incandescent lamp for 8 hours! That’s pretty impressive!
2. LEDs don’t heat up as much as standard bulbs
One major drawback with traditional incandescent lighting is that they get hot and produce excess heat which can damage your home and harm you if you touch them while they are hot (more on this in the next point). Because LEDs don’t get hot, they can be used anywhere around your home without causing problems such as damaged wiring or being in the way.
3. LEDs have a longer life span than standard bulbs
LED light bulbs are more durable than standard incandescent bulbs. LED light bulbs last up to 25 times longer than standard incandescent light bulbs, making them an excellent long-term investment. This means that you don’t have to buy new LED lights as often as you would incandescent lights and they will save you money over time. Plus, they’re more environmentally friendly and won’t add heat or damage your home or your body when used around it!
4. LEDs use less energy than traditional incandescents
LEDs use less energy than traditional incandescent, but this is not the whole story because we also need to consider how much power each type of bulb uses. Let’s compare 100-watt LED lights in comparison with 100-watt incandescent light bulbs for a single bulb (which will be called “Incandescent Light Bulb A” for simplicity’s sake). Incandescent Light Bulb A requires 10W of electricity to produce 1W of light and the remaining 88W is spent on heat, cooling, and other functions (see point #2 above).
5. LEDs are more energy efficient than incandescents
The main reason that LEDs are so much more efficient than traditional incandescent bulbs is that the LED lights use less power to produce the same amount of light because they don’t get as hot as incandescent bulbs do. The fact that they don’t get as hot means that they consume less power in the first place and also means that they will last longer before needing replacement. This makes them a better long-term investment.
When buying bulbs, make sure to look at the cost per kilowatt hour. You need to compare the cost per kilowatt hour between incandescent, halogen, fluorescent, and LED bulbs. This will tell you how much each type of bulb costs per hour to run. Since LEDs last 25 times longer than traditional bulbs and use a lot less energy, they’re actually cheaper in the long run. With modern technology, it’s easier than ever to invest in LEDs. Do your research, and you can save money while also helping the environment.
