Right now, LED lighting is more prevalent in commercial applications than in residential settings. (If you’re interested, here are some examples/images of LED lighting used in commercial applications, compliments of Cree LED Lighting Solutions.)
Why are so many companies jumping on the LED bandwagon? It has a lot to do with the bottom line: LEDs are a better investment over the long haul since they last so much longer than the old-fashioned incandescent bulbs.
Although LED lights are used more often in commercial applications currently, this will change as the price of LED light bulbs continues to drop and people start realizing the benefits of LED lights. In the meantime, you may be wondering what’s so great about LED bulbs?
Here are some reasons why LED lights are better:
While most fluorescent lights (CFLs) cannot be dimmed and many can flicker, LED lighting uses solid-state technology, which allows for dimming and eliminates flickering. LED lights can withstand extremely cold conditions, so they are very durable (this is one of the reasons LED lights are so popular for outdoor lighting applications).
LEDs turn on instantly, so there is no warm-up time. In fact, they are ideal for uses where there is a need for frequent “on/off” cycling. This is an advantage over fluorescent lamps, which fail faster when turned on and off often. LED light bulbs do not contain breakable filaments or glass, making them shock-resistant, unlike fluorescent and incandescent bulbs, which are fragile.
Most important of all is the fact that LED light bulbs last 25 times longer than the old-fashioned incandescent bulb. Instead of 1,000 hours, which is the typical rated life of standard incandescent bulbs, the rated life of LEDs is usually 25,000 hours or more. (The rated life of CFLs is about 9,000 hours.) This makes the LED light bulb cost-effective in the long run.
LED lighting can save up to 85 percent of the electricity used by incandescent bulbs and up to 50 percent of electricity used by fluorescents.
Unlike the old-fashioned incandescent, which wastes 90 percent of the energy it uses by giving off heat, LED bulbs do not create heat. Since LED light bulbs produce significantly less heat than incandescent bulbs, they reduce the need for air conditioning in the home.
While it’s true that LED light bulbs are more expensive, they provide real cost savings because they consume less energy – resulting in lower energy bills. This is another reason why companies understand that LED lights are a better investment over the long haul.
LED light bulbs do not contain mercury – making them more earth-friendly than CFLs, which contain mercury and thus contribute to landfill poisoning if not disposed of properly.
The U.S. Department of Energy estimates that widespread adoption of LED lighting by 2025 will reduce electricity demands from lighting by 62 percent; eliminate 258 million metric tons of carbon emissions; reduce the amount of materials dumped into landfills; and avoid the building of 133 new power plants.
The only drawback to LED light bulbs is they require an initial investment. It’s true you pay more for an LED light bulb upfront, but you save that money in the long run. You also save time since you don’t have to constantly change LED light bulbs.
