With an ever-increasing number of people shifting away from traditional light sources such as incandescent bulbs, LED lights are more popular than ever.
LED or light-emitting diode is the technology that powers LED bulbs. It works with the help of an electric current passing through the diode. These diodes provide light in an LED bulb when electricity is supplied.
The advantages of LED bulbs are well-known, such as being brighter than incandescent bulbs, not requiring heat to produce light, lasting longer, and most importantly, being more energy-efficient.
LED bulbs are available in several different sizes, shapes, colors, and temperatures. You can also use such lights in vehicles, bicycles, and more.
Before we talk about the different types of LED lights available on the market, let us look at some of the advantages they offer. So, let us get straight down to it.
Advantages Of LED Lights
We have already mentioned some of the benefits that LED lights offer in the preceding section. However, now we are going to discuss these advantages in greater depth for better understanding.
-
Energy-Efficient
As most of you must be aware, one of the most critical factors that make LED lights the best option for lighting purposes is higher energy efficiency. Compared to incandescent bulbs, LEDs are up to 90% more efficient than incandescent bulbs and up to 40% more efficient than CFLs.
As per the United States Department of Energy report, residential LED lighting uses 75% less energy than incandescent bulbs. Besides being highly energy-efficient, LED lights are much brighter than incandescent and fluorescent lights. It means it is possible to use a lesser number of them while getting more radiance.
-
Longer Lasting
LED lights last much longer than other types of lighting, such as incandescent or halogen bulbs. It is because of the way they function. While incandescent bulbs produce light when a tungsten filament is heated within a glass dome, halogen lights contain halogen that pushes the burnt tungsten back into the filament.
On the other hand, LED bulbs have light-emitting diodes mounted on chips that illuminate when an electric current passes through them. Unlike incandescent bulbs that stop working once the filament burns out, LED bulbs can last up to 25,000 hours or even up to 50,000 hours. And, even after that, they only lose 30% of their brightness.
LED lights can last for decades without needing replacements. A phenomenon called lumen depreciation makes LEDs lose their brightness slowly over time, instead of completely burning out like incandescent bulbs. The rating on LEDs indicates after how many hours, the bulb will dim to 70% of its original brightness.
-
More Economical
Due to various factors such as higher energy efficiency, lower maintenance, and more excellent durability, LEDs automatically become the most cost-effective option for lighting in the long run.
While the initial cost may be higher than traditional incandescent bulbs, you will be able to save more over a more extended period. Even the upfront costs have come down, leading to more significant savings. On top of that, various manufacturers are conducting research and trying new technologies to bring down the price even further.
Besides lower direct costs, LEDs also help you save more by reducing indirect costs. A perfect example of this is the cost of air conditioning, which is higher when you use incandescent bulbs to generate heat. LED bulbs do not produce heat, helping reduce air conditioning costs as well.
-
Wide Application
Traditional forms of lighting such as incandescent bulbs and halogen lamps are limited in shape and, by extension, in the application. You can only use these lights for conventional lighting purposes.
LEDs, however, are available in several different forms, sizes, temperatures, and colors. The smaller size and cooler operating temperature make them ideal for a variety of other purposes. You can use LEDs to light areas that conventional light sources cannot reach. LED lights are available not only for residential applications but also for commercial and industrial purposes.
Additionally, you can use these on daily use objects and vehicles, street lights, smartphones, TVs, and more. The versatility of LED lights knows no limits.
-
Environment-Friendly
With the global population becoming more aware of adopting environment-friendly technologies, LED lights make a compelling choice. One of the critical factors that make LED lights great for the environment is their durability.
Since they last for a long time, it results in a lower replacement rate and, therefore, lower production. Additionally, LED lights are brighter than conventional bulbs and CFLs, which means you need a fewer number of them than other types of lighting.
Higher energy efficiency is another factor that makes LEDs better for the planet. While fluorescent bulbs convert 95% of the energy into heat and 5% into light, LEDs are the opposite. They convert 95% of energy into light, and only 5% is wasted as heat.
Finally, fluorescent lights, while being excellent in energy efficiency, also contain toxic chemicals such as mercury. These chemicals can leach out and contaminate the environment and require proper disposal. LEDs are free of such chemicals and hence do not require special disposal. Also, they emit a lower amount of emissions, which is an added advantage.
The LED lighting industry is continuing to grow and evolve, with more consumer-friendly products available. It will contribute to the rapidly increasing popularity of LED lights for multiple purposes.
Learning about the various advantages of LED lights over older lighting technologies, we can now focus on understanding the different types of LED lights available on the market.
