The first LED light was created in 1962; however, it wasn’t for another 50 years before LEDs really became popular and began replacing incandescent bulbs. Now, it’s predicted that by 2025, 9 out of 10 lightbulbs that are sold will be LEDs, according to Goldman Sachs.
8 Compelling Reasons to Switch to LED Lights
With the amount of energy saved with LEDs along with the cost effectiveness of these lights, it’s hard to find a reason that you wouldn’t want to use them. However, if your house is already filled with incandescents and CFLs, it can be a bit of a project to switch out all of your lights. Here are 8 reasons why it’s worth using LED lighting.
Reduces Energy Usage
If you only needed one main reason to switch to LED bulbs, it should be due to the fact that these bulbs can reduce your energy bill and carbon footprint. Compared to incandescent lights, LEDs consume 75% less energy.
Additionally, even if your house is filled with CFL bulbs, by switching to LEDs, you’ll reduce your energy usage by about 50%.
According to Energy.gov, if there is widespread use of LED lights by 2027 in the U.S., it could result in saving roughly 348 TWh of electricity. To put that into perspective, that would be a savings of over $30 billion, based on the electricity prices we have today.
Lower Your Energy Bill
By switching to bulbs that use less energy, that also means that your energy bill will be reduced.
According to an analysis done by the Consumer Federation of America, a U.S. home that has an average of 20 light bulbs could save $1,000 over the course of 10 years by switching to LED lights. Even by only changing out the bulbs in the 5 most used spots in your home could give you a savings of $75 per year.
Have a Longer Lifespan
When LED lights were first introduced, they were relatively expensive and cost about $100 per bulb. To switch out all of the bulbs in your house was an investment; however, the upside was that LEDs had a longer lifespan than all other types of bulbs.
Now, LED lighting is much cheaper, making the longer lifespan an even bigger benefit of these bulbs. According to Consumer Reports, LED lights will keep their brightness for 23 years when they are used 3 hours per day.
This means that a bulb’s lifespan is about 25,000 hours before the light begins to lose some of its brightness. After the 25,000 hours, the LED light will still work; it just won’t reach the maximum brightness that it originally had. The bulb could still shine for an additional 25,000 to 50,000 hours!
Even if we take the minimum lifespan of an LED light (25,000 hours), here’s how it compares to other light’s lifespans:
- Incandescent bulbs: 1,200 hour lifespan per bulb
- CFL bulbs: 8,000 hour lifespan per bulb
Based on this, you would need to replace an incandescent bulb 21 times and a CFL 4 times in order to match the 25,000 hours that you get from one LED bulb.
Increase Productivity Levels
The American Society of Interior Designers conducted a study and found that 68% of employees complain about the lighting in their office or building. The complaints stemmed mostly from offices either being too dim or too harsh.
Dim lighting can strain your eyes and cause drowsiness, which also results in lower productivity levels. With harsh lighting, headaches and migraines can occur more often.
- Increase productivity levels
- Longer attention spans
- Better sleep at night
Because LED lights have the ability to change color temperature, offices, schools, and homes can customize the lighting to increase productivity. Here are examples of when certain color temperatures work best:
- Warn Temperature (2,000K – 4,000K): Creates a sense of calmness and relaxation, which is great for break rooms, one-on-one meetings, and in bedrooms an hour before you sleep.
- Neutral Temperature (4,000K – 5,000K): Adds a welcoming vibe to a room along with promoting alertness, and ideal for company meetings, conference rooms, and living rooms.
- Cool Temperature (5,000K – 7,000K): Improves overall productivity and moods, which is good for classrooms, main office spaces, and kitchens.
Operate Better in Cold Climates
If you live somewhere that experiences a decent amount of cold weather throughout the year, LED lights are preferred over other types of lighting. Based on research from the Lighting Research Center, in cooler temperatures, LEDs are 5% more efficient, have a higher output, and they can last longer than incandescent bulbs.
LED bulbs are also great for freezers because they can withstand freezing temperatures and still be more efficient.
Ability to Dim
Unlike traditional lights that only have one brightness setting, LEDs have the ability to shine at any range in their given output (from 0% – 100%).
Similar to the benefits of being able to change the color temperature on these bulbs, having the ability to adjust the brightness can create a sense or calmness when the brightness is reduced to 50% or lower. On the flip side, increasing the brightness helps with keeping you alert.
In order to dim LED lights, you do need specific hardware, such as trailing edge dimmers, in order to allow the LEDs to utilize their dimming function. Once this is set up, dimming LED lights reduces the amount of energy used per light. This is because of how bright the light is directly related to the LED current.
Not only does this save energy, but it also increases the overall lifespan of each dimmable LED.
Generate Minimal Heat
LED lights produce very little heat because not much infrared radiation heat is created. At first, this might not sound like a big deal; however, this is one of the biggest benefits of LEDs.
Since there’s so little warmth that comes from them, they are much safer than CFLs, incandescents, and other typical lights you might buy. These other lights can become very hot after being on for a couple hours, and if you touch them or if they break, it can become hazardous.
For example, about 90% of the energy consumed by incandescent lights is focused on generating heat. Not only is this a waste of energy, but it’s also a safety concern due to how hot the bulb becomes.
Designed for Durability
LED lights are designed to withstand falls and drops better than traditional lights. Standard lights are usually created from glass, which is very fragile to the touch. Even when dropped from a small distance, it’s no surprise when these bulbs shatter.
While there are LED lights that use glass, plastic and polycarbonate are other popular options. Polycarbonate is especially useful when the lights are meant for outdoors, where they can be exposed to various weather conditions.
The longevity, cost-effectiveness, and reduced carbon footprint of LED lights are just a few of the reasons it’s worth upgrading your home to these better bulbs. If your house is filled with CFLs and incandescents, start small by finding the areas in your home that are used the most and replace the bulbs there.
