The more lumens, the brighter the light. The LED bulbs require much less wattage than the CFL or Incandescent light bulbs, which is why LED bulbs are more energy-efficient and long lasting than the other types of bulb.



Besides, are LEDs more efficient than CFLs?

Efficiency—While incandescent bulbs and CFLs generate most of their energy in heat, LEDs are cool to the touch—which translates into less wasted energy. LEDs are more efficient than even CFLs: A 16.5-watt LED bulb is equivalent to a 20-watt CFL and a 75-watt incandescent.

Beside above, which light bulbs are the most energy efficient? The most energy efficient light bulbs are compact fluorescent light bulbs, or CFLs, and LED bulbs. CFLs use mercury to cause a phosphor coating on the inside of the bulb of fluoresce, thereby producing light, while LED bulbs use light-emitting diodes as their light source.

Also to know is, which is more harmful LED or CFL?

LED bulbs are way better than CFLs simply because they are durable, energy efficient, environment-friendly and emit less heat. They do not contain harmful substances like mercury and are more cost-effective. They also use less power per unit of light generated.

Should I replace CFL bulbs with LED?

A new study from University of Michigan researchers recommends replacing all incandescent and halogen light bulbs in your home now with compact fluorescent lamps (CFLs) or LEDs. LEDs are long-lasting light bulbs that use less energy than incandescent, halogen or fluorescent bulbs to provide the same light output.

Why is CFL better than LED?

LED bulbs require much less wattage than CFL or Incandescent light bulbs, which is why LEDs are more energy-efficient and longer lasting than their competitors. The lower the wattage needed, the better.

Is it worth switching to LED bulbs?

The lifetime cost of LED bulbs
The first thing you need to realize about the lifetime cost of LEDs is that they are VERY energy efficient, as in 80% more efficient than incandescent bulbs. No doubt, LEDs are just more energy efficient – a 10 watt LED bulb does the same work as a 60-watt incandescent bulb.

Which is cheaper CFL or LED?

Cost Winner: LEDs (in the long run)
Initially LED bulbs are slightly more expensive than the CFL bulbs. A six-pack of CFL bulbs typically costs around $22-25, while a six-pack of LED bulbs costs around $28-30. Although LED's have a higher initial cost, they will save you money in the long run.

Are LED lights bad for your eyes?

LED light can damage eyes, health authority warns. The "blue light" in LED lighting can damage the eye's retina and disturb natural sleep rhythms, France's government-run health watchdog said this week. LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness.

Which light is better for eyes CFL or LED?


Compact Fluorescent Lights (CFLs): CFL bulbs produce fewer UV rays and are more energy efficient than bright white incandescent and fluorescent tube bulbs. They are less energy efficient than LED bulbs, but they usually cost less up front. Many consumers also believe CFL bulbs are harmful due to their mercury content.

What is 30w LED equivalent to?

A 30w LED floodlight is usually equal to a 300w halogen floodlight. Top-spec 30w LED floodlights such as Osram are 100 lumens per watt, but not all lower-spec 30w LED floodlights are as bright.

How bright is 1800 lumens?

For instance: 40 Watt incandescent lamp produces only 380-460 lumens and uses 40 Watts of energy per hour. 100 Watt incandescent lamp produces 1700 – 1800 lumens and uses 100 Watts of energy per hour. Direct sunlight is around 100k lumens and uses no amount of energy per hour.

What is 60 watts in LED?

An LED that uses 60 watts is in no way comparable to an incandescent bulb that uses 60 watts. In fact, a 60-watt LED just may blind you. LEDs are designed to use less energy and naturally have a lower watt rating. This means it's useless to use watts to determine brightness.

What is bad about LED lights?

LED lights emit light from the short-wave, high-energy blue and violet end of the visible light spectrum. The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration.

Are LED lights safe for human eyes?


The light sources we create in LED bulbs and digital devices, however, lack the intensity of the sun. You can, and do, stare directly at these lights frequently and for extended periods. Unfortunately, while the light sources don't cause the immediate pain and recoil caused by the sun, they still damage our eyes.

Which LED light is best for eyes?

The Best Kinds of Light for Your Eyes
Artificial warm light includes sources like incandescent bulbs and LED bulbs, which are more energy efficient. You can also buy full spectrum light bulbs for your light fixtures that attempt to mimic the warm natural lighting of the sun without the harmful UV rays.

What happens if you break an LED light bulb?

If an LED lightbulb breaks in your home or workplace: Put on protective gloves and sweep up the LED pieces into a plastic bag using a stiff piece of cardboard (if you use a broom, consider disposing of the broom after using it). Next, use sticky tape to pick up any small fragments left over.

Do CFL light bulbs cause cancer?

Doctors at Stony Brook University in New York found that CFL bulbs produce significant levels of UVA and UVC emissions, which are harmful to human skin. This ultraviolet radiation can cause skin to age and burn and ultimately lead to skin cancer.

Do LED lights cause headaches?

LED Lighting Versus Fluorescent Lighting
We know that both LEDs and fluorescent lights can cause visual, headache and migraine symptoms. This occurs because LEDs can only be completely on or completely off, so they have to produce the flicker in order to simulate these dimmer settings.

Are CFL lights bad for you?


CFL bulbs are dangerous because of ultraviolet radiation leakage. Two readers pointed with alarm to a 2012 study by Stony Brook University researchers, which found that most CFL bulbs have defects that allow UV radiation to leak at levels that could damage skin cells if a person is directly exposed at close range.

Which Colour is best for eyes?

Green eyes: The most attractive eye color?
  • Green: 20.3%
  • Light blue: 16.9%
  • Hazel: 16.0%
  • Dark blue: 15.2%
  • Gray: 10.9%
  • Honey: 7.9%
  • Amethyst: 6.9%
  • Brown: 5.9%

Is blue light bad for eyes?

Blue light exposure may increase the risk of macular degeneration. The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina.
