What are light-emitting diodes (LED)?

in light-emitting •  4 years ago 

"The light-emitting diode (LED) is one of today's most energy-efficient and rapidly-developing lighting technologies. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting."

"An LED light bulb typically uses up to 90% less energy than regular incandescent or halogen light bulbs and lasts far longer. This opens up savings in two ways:

On your electricity bill
On having to change your light bulbs less often"

"One simple way to conserve energy and save money is to switch to LED light bulbs. Each bulb you install uses 90% less electricity than incandescent bulbs. LEDs also come in a wide variety of colors and brightness options, allowing you to light your entire home, your way.

Compared to incandescent bulbs, LED light bulbs:

Last up to 13 years
Save you more than $100 per bulb over their lifespan
Are available in multiple color and brightness options
Are always cool to the touch
Can be safely recycled"

"LEDs use much less energy than incandescent bulbs because diode light is much more efficient, power-wise, than filament light.

LED bulbs use more than 75% less energy than incandescent lighting. At low power levels, the difference is even larger."

"LED or the light-emitting diode light bulb is a good energy efficient option for lighting, often beating out CFL light bulbs in power efficiency and longevity at a similar price. A typical cheap (60 watt equivalent to incandescent) LED light bulb is advertised as providing 800 lumens, lasting up to 10,000 hours at 10 watts."

Light-emitting diodes (LEDs) are semiconductor devices that emit light when an electric current passes through them. Unlike traditional incandescent bulbs that use a filament to produce light, LEDs generate light through electroluminescence.

I’m thrilled to share that I chose to install LED Lights for House https://ledex.ie/collections/residential-lighting from Ledex for my house in Ireland. I was looking for a modern and sleek lighting solution that would complement my home’s decor. Ledex’s LED Lights provide a clean, contemporary look with a variety of styles and color temperatures to choose from. The result is a beautifully illuminated space that perfectly matches my aesthetic preferences.
