Advantages of LED lights
Energy efficient: The biggest advantage of LED lights is that they are extremely energy efficient.
LED bulbs use 90 per cent less energy compared to incandescent or halogen bulbs.
Longer life: LED bulbs have a much longer lifespan as compared to traditional light bulbs.
What is so special about LED lights?
LEDs don’t require a high voltage to operate. This makes it easy to use LEDs outside by connecting them to a solar power source. They also don’t become hot to the touch as they don’t produce the same amount of heat as incandescent bulbs. This also means that LEDs are ideal for lighting food displays and textiles.
Why are LEDs being used more?
Energy Efficient. LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights. 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. Less energy use reduces the demand from power plants and decreases greenhouse gas emissions.
What are the advantages of LED lights?
Benefits Of LED Lighting. LEDs are extremely energy efficient and consume up to 90% less power than incandescent bulbs. Since LEDs use only a fraction of the energy of an incandescent light bulb there is a dramatic decrease in power costs.
Do LED lights really save money?
LEDs cost 40 times more than incandescent, but since they use about 75 percent less electricity, they win in the long run. The LED bulb uses only 25 cents’ worth. So the LED saves $1.23 per year. Since it costs $20, it will take 16 years to recoup the cost in electricity savings.
What will replace LED lights?
“It’s the same materials, but you put two mirrors on either side of the LED and it breaks into a laser. In theory, that means per square centimeter, a laser diode can produce 2,000 times as much light. Simply replacing the light emitting diodes in a typical LED bulb with a laser diode wouldn’t work.
Why are LED lights bad?
Because LED light is so concentrated and has high blue content, it can cause severe glare, resulting in pupillary constriction in the eyes. Blue light scatters more in the human eye than the longer wavelengths of yellow and red, and sufficient levels can damage the retina.
Why do LED lights use less power?
LEDs emit almost no forward heat while traditional bulbs like incandescents convert more than 90% of the total energy used to power them directly into heat. That means only 10% of the energy powering incandescent lights is actually used for light (which also makes them extremely inefficient compared to LEDs).
Do LED lights use less power?
Both CFLs and LEDs use considerably less electricity than traditional bulbs. As you can see, buying longer-lasting, more efficient light bulbs can really pay off over time. By comparison, it would cost just $48 using a handful of CFLs, or $38 using a single LED light bulb — a savings of more than $150 either way.
Is led good for eyes?
Eco-friendly LED lights may damage your eyes, according to new research. A study has discovered that exposure to LED lights can cause irreparable harm to the retina of the human eye. A Spanish study has shown that the light emitted by LED bulbs can damage the cells in the retina.
What are the disadvantages of LED light bulbs?
Disadvantages. High initial price: LEDs are currently more expensive (price per lumen) on an initial capital cost basis, than most conventional lighting technologies. Over-driving an LED in high ambient temperatures may result in overheating the LED package, eventually leading to device failure.
What are the disadvantages of LEDs?
Disadvantages of using traditional LEDs. High price: LEDs are currently more expensive, price per lumen, on an initial capital cost basis, than most conventional lighting technologies. The additional expense partially stems from the relatively low lumen output and the drive circuitry and power supplies needed.
Are LED lights dangerous to health?
LEDs use significantly less energy than even CFLs, and do not contain mercury. But LEDs do have a dark side. A study published in late 2010 in the journal Environmental Science and Technology found that LEDs contain lead, arsenic and a dozen other potentially dangerous substances.
