What is LED lighting and how does it work?
LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light.
What is the difference between an LED light and a regular light?
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. Bright LED flood lamps use only 11 to 12 watts while creating a light output comparable to a 50-watt incandescent bulb.
What is so special about LED lights?
LED lights are free of all harsh chemicals and they do not emit UV rays. LED lights are also 100% recyclable and can significantly reduce your carbon footprint. With one LED light able to do the work of roughly 25 incandescent light bulbs over its lifetime, LED lights also help save on materials and production.
Are LED lights better?
The light-emitting diode (LED) is today’s most energy-efficient and rapidly-developing lighting technology. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting.
Are LED lights electric?
An LED lamp or LED light bulb is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps.
Are LED lights white light?
Unlike incandescent lamps, LEDs are not inherently white light sources. Instead, LEDs emit nearly monochromatic light, making them highly efficient for colored light applications such as traffic lights and exit signs. However, to be used as a general light source, white light is needed.
How can you tell if a light is LED?
If you can see small chips that look yellow while the bulb is turned off, its an LED. If these details are hidden away, you can Google the partnumber on the base, or guess based on the light quality. If its greenish, its a CFL. If its a harsh bluish white its an LED.
How long can LED lights stay on?
between 35,000 and 50,000 hours Type of Bulb Average Lifespan When should you turn it off? LED 35,000 – 50,000 hours Can be left on 24/7 Incandescent 750 – 2,000 hours Turn off when not needed.
What is the disadvantage of LED light?
Perhaps the biggest drawback of LED light bulbs is that they emit more blue light than incandescent bulbs, which are more on the red end of the spectrum. Blue light can cause a disruption in your circadian rhythm, negatively affect your ability to fall asleep and the quality of your sleep.
Can you use LED lights in any fixture?
When it comes to LED light bulbs, they will turn on and work in any light fixture that provides them at least the minimum wattage they’re specified for. Some LED bulbs may even be tolerant of too little or too much wattage, to a certain point. This is yet another thing they share with incandescent and halogen bulbs.
Do LED lights give off heat?
It is true that there is no heat, IR, in the beam. However, the LED fixture itself, does produce heat. However it may become warm, or hot, to the touch.
Are LED lights still popular?
“We absolutely expect LED technology in four or five years to be the most popular lighting technology that’s out there.” Last year, LED sales, though small at about 3 percent of the residential market by some estimates, grew faster than those of any other lighting technology, according to retailers and analysts.
How much do LED lights cost?
Cost Comparison Between LEDs, CFLs, and Incandescent Light Bulbs LED Incandescent Cost per bulb $5 $1 KWh of electricity used over 25,000 hours 212.5 1500 Cost of electricity (@ 0.10 per KWh) $21.25 $150 Bulbs needed for 25,000 hours of use 1 21.
What is the price of LED light?

Does LED lights increase electric bill?
LED strip lights do not cost a lot of electricity compared to traditional incandescent lights. Consumption is directly determined by the length of the strip light and its light density. A standard 5-meter strip will cost less than $3 a year to run, on average.
Do LED lights consume more electricity?
Yes! LED lights consume 80-90% less energy than incandescent bulbs, and last up to 100,000 hours, versus 3,000 hours for an incandescent. Combine this with the durable construction of LEDs, and savings extend beyond electricity.
What are the pros and cons of LED lights?
Blog The Pros and Cons of LED Lights. July 10, 2020. Pro: Long Lifespan. An LED light bulb has the longest lifespan of all the bulb options. Con: An Upfront Investment Is Required. Pro: Energy-Efficient. Con: Not Great for Dimmers. Pro: Produce Less Heat. Con: They Can Fail Under Heat. Pro: Environmentally Friendly.
How much does it cost to run a LED light bulb for 24 hours?
A 10 watt LED for 24 hours 240 watt hours at 25 cents a KWH around 6 cents. Why run it in the day! You multipy the rating of the bulb (normally printed on the bulb in kW or Watt) by your electricity rate (as indicated on you electricity bill in $/kWh) by 24 hours. That is you cost.
Do LED lights save money?
LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs. While LEDs are more expensive than traditional incandescent bulbs, they still save money because they last a long time and have very low energy use.
Are LED lights cheap to run?
LED bulbs use only a fraction of the electricity consumed compared to traditional incandescent bulbs. They are cheaper to run than fluorescent lighting. Also, they can last for up to fifty times longer.
