Story at a glance:

  • LED lights have been rising in popularity consistently in recent years.
  • Among the many benefits of LED lighting is the fact that they consume significantly less energy than incandescent and even CFL bulbs.
  • LED lights are adaptable, directional, dimmable, and ever-improving compared to other lighting options.

The technology behind LED lights has been around for decades, but only recently have they become affordable and reliable enough to rise in popularity dramatically. With perks starting with energy efficiency to meet virtually any energy targets and a long lifespan, LED lights are both environmentally responsible and budget-friendly.

Light-emitting diodes, or LEDs, are a solid-state lighting solution that uses a semiconductor to convert electricity into light, according to the US Department of Energy. This means LED lights do not require a breakable glass bulb like traditional lights.

Plus, LED lights can be used anywhere: from sports arenas to industrial manufacturers to the home. They perform reliably and safely in various design applications. If this short list of the benefits of LED lighting isn’t enough to convince you it is a solution worth investing in, maybe one of the following 16 will.

1. Energy efficient

LED lights use up to 85% less energy than traditional bulbs, according to The New York Times. This means LEDs produce savings in electricity costs and simply do well by the environment. In 2007 Congress passed the Energy Independence and Security Act, which, though challenged by the Trump administration, helps the US stay on track with the global shift toward LED and other energy-efficient lighting solutions for everyday light bulbs.

2. Return on investment

As LEDs become more commonplace, individuals and the US as a whole will notice significant energy savings. According to the US Department of Energy, “Switching entirely to LED lights over the next two decades could save the US $250 billion in energy costs, reduce electricity consumption for lighting by nearly 50%, and avoid 1,800 million metric tons of carbon emissions.”

On a smaller scale, E3 used Energy Focus LED lights to retrofit the Big Sandy Independent School District in Eastern Texas in 2016. “Cost was a major component for Big Sandy. The LED’s use 15 to 18 watts per lamp as opposed to the 32 to 36 watts per lamp used by the fluorescents. So it saves the schools money and they get a good return on investment,” Tim Evans, vice president of E3, told gb&d.

3. Long lifetime

LEDs use dramatically fewer watts than traditional bulbs to produce bright light, which means they also last much, much longer. Most LEDs last a minimum 25,000 hours, according to NOPEC, a nonprofit energy supplier in Northeast Ohio. NOPEC says if you were to keep your LED bulb on all day every day it would be about 15 years before you’d have to replace the bulb.

4. Low radiant heat

Among the benefits of LED lighting is the fact that they radiate very little heat, particularly compared to CFL and incandescent lights. According to the US Department of Energy, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat in comparison to LEDs. This makes LED lights less hazardous, particularly in terms of fire safety.

5. Bright and intense light

LEDs do not compromise brightness or intensity for energy efficiency. They compete with incandescent and CFL bulbs in terms of brightness, making them a good addition to workspaces where bright light contributes to productivity.

6. Instantaneous light

LED lights have less warmup time compared to other bulbs, brightening rooms and outdoor spaces from the moment the switch is flipped.

7. Design flexibility

The structure of LED lights allow them to be used both functionally and artistically. In spaces of all kinds, LED lights offer design flexibility. In the Yotel NYC, Focus Lighting utilized LED lights in all kinds of applications, from pin spotlights to floor lamps to lit ceiling panels, to adhere to the hotel’s strong brand identity.

8. High Color Rendering Index

Many LED lighting options offer a very high Color Rendering Index (CRI), which means they reveal the true color of whatever they illuminate. Philips, one of the leading LED lighting companies, makes LED lights with a CRI of at least 80 compared to natural light’s 100. This allows consumers at home to predict how their outfit will look when they step outdoors, for example. The high CRI of LEDs is also useful in broadcasts, where bright and color-accurate light allows nighttime sports games to look vibrant and real, even on television.

9. Ability to dim

LED lights can be made to dim just the same as incandescent and CFLs. This increases energy savings and allows the light to adjust to suit the needs of a space throughout the day.

10. Range of colors

LEDs come in many colors, with surprising and increasingly impressive accuracy in terms of color matching. In one of the rising wellness design trends of today, LEDs perform a crucial role. In accordance with people’s circadian rhythms, LEDs can be programmed to adjust in color and warmth throughout the day.

11. Sturdy

LEDs utilize semiconductor material rather than a filament or neon gas. The light-emitting diode is a tiny chip enclosed in a plant epoxy, which makes LEDs far sturdier than traditional incandescent bulbs or neon tubes, according to the Department of Energy.

12. Great in case of emergencies

Because LED lighting provides bright light at such low wattage and can therefore last a very long time, they are a great solution for emergency lighting.

13. Environmentally friendly

LEDs do not contain mercury, and if their aluminum heat sinks were recycled, their life cycle impact would be noticeably reduced. Overall their energy savings and basic construction allow LEDs to win the ticket for most environmentally friendly light, according to a three-part Energy Department-funded study.

14. Operable in many temperatures and climates

Particularly in cold environments, LED lights perform exceptionally well. Recently they have progressed to perform in hot, humid environments as well. Industrial spaces are often not climate-controlled, but Flex Lighting Solutions is one company whose LEDs are a leading option for industrial lighting because of their impressive thermal management technologies.

15. Directional light

By their very nature, LEDs emit light in one direction instead of all around them. This 180-degree illumination allows the light to be more precise and useful—perfect for recessed and task lighting—and contributes to energy savings because no light energy is wasted or trapped.

16. Reliable performance

Again, the basic technology behind LEDs has been around for years and years. Although the bulbs dim toward the end of their very, very long lifetime, their performance overall is reliable and trusty across spaces, even in conditions with inclement weather or frequent impact.
