LEDs, or light-emitting diodes, are gaining favour with consumers ahead of options like incandescents, halogens, and even compact fluorescent lights (CFLs). LEDs tend to have far longer lifespans than other types of light bulbs, and they can be used in a huge variety of devices. Whether you're already using LEDs at home or at work, or you're looking to find out more about them, these 10 interesting facts are some of the reasons to appreciate the utility and benefits of LEDs in our lives.
LEDs can have a useful lifespan of up to 50,000 hours. This means an LED switched on for seven hours a day, 365 days a year, can last for nearly 20 years before you need to replace it. In contrast, a traditional incandescent light bulb may last only 750 to 2,000 hours, and a CFL up to 10,000. A linear fluorescent, lasting up to 30,000 hours, would be the alternative that comes closest to LEDs' long lifespan yet still falling far behind the long-lasting power of LEDs.
Additionally, LEDs don't suddenly burn out like incandescents, and leave you with no light. Instead, they fade away over time, and at the end of their effective life, they still light up, typically offering around 30% of their original lighting power.
Since LEDs can last up to 10 times longer than halogens while using only 25% of the energy to generate the level of lighting, LEDs can be much cheaper to use in the long run, despite costing slightly more at the outset. At the same time, LEDs are getting cheaper to buy and prices could be as low as $10 for one light bulb. Research suggests the cost savings over 10 years for LEDs compared to CFLs could be nearly $10, and almost $110 when compared to halogens.
Because LEDs are easy to maintain and long-lasting, they have a wide variety of applications beyond lighting space. They're so versatile they're used for everything from lighting up watches to data transmission in remote controls. LEDs are used also in traffic lights, digital clocks, and TV screens.
LEDs emit less heat than incandescent light bulbs, so when it's the height of summer and you're looking for ways to stay cool, you'll be grateful for your LED lights. The cooling factor of LEDs reflect their efficient design: LEDs direct most of the electricity into lighting rather than heat, unlike other lighting technologies.
LEDs give off little or no UV rays, which means your fruit and veggies might be able to retain higher nutrient levels. While the impact in your home is probably minimal, for supermarkets, restaurants, and commercial kitchens, the impact could be notable. Additionally, bugs are attracted to UV rays, so using LED lighting could help shops and other commercial operations keep the insects away.
LEDs switch on and reach maximum brightness instantly. This offers extra convenience. For example, you won't need to wait for the light to reach full brightness before carrying out activities like reading.
LEDs can tolerate temperature extremes, making them a useful, durable option to have if you live in an area with varying temperatures throughout the year. LEDs are known to operate successfully in harsh environments and they can tolerate temperatures that range between -40 C to +85 C. This makes them ideal in regions with an extreme climate and highly durable options for any home or workplace.
The energy efficiency of LEDs is astounding, as LEDs can save you up to 89% of the energy you would otherwise be using with a halogen light bulb. When combined with their long lifespan, cooling factor, and tolerance of temperature extremes, this energy-saving advantage makes LEDs the top choice for lighting.
LEDs may have a much smaller environmental footprint than options like incandescent light bulbs. This is because LEDs contain no mercury and may be lower in other harmful chemicals like lead and cadmium. In addition, since LEDs are highly efficient, they use less energy to produce the same lighting effect. Both of these factors translate to a reduced environmental footprint for LEDs.
In contrast to the Watts (W) used for incandescent bulbs, LEDs use Lumens (lm) to indicate brightness. For the equivalent of 100 W, look for an LED with a light output of 1500 lm. An LED with 250 lm would give you the same brightness as a 25 W light bulb.
LEDs are the probably the best option when it comes to choosing a light bulb for your home or office. The latest LED technology has ensured LEDs are superior to options like CFLs and incandescents in terms of lifespan, long-term cost, and durability and utility. By choosing LEDs over other options, you'll save money and help out the environment.
