Both breast and prostate cancers are hormone-related..

Why are LEDs better 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.

Is blue light bad for eyes?

Symptoms of eyestrain include sore or irritated eyes and difficulty focusing. Retina damage: Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems like age-related macular degeneration.

Which Colour is best for eyes?

Green, the mixture of blue and yellow, can be seen everywhere and in countless shades. In fact, the human eye sees green better than any color in the spectrum.

Which is cheaper LED or CFL?

LED costs more at purchase, but lasts longer. CFLs are cheaper, but if broken become not so convenient very fast. Other people decide that CFL lighting is closer to what they’re used to and therefore choose these bulbs to replace incandescent bulbs as they blow out.

Which light is good for eyes CFL or LED?

The Best Light Bulbs to Buy for Your Eyes There are several other light bulbs that are a better choice for your eye health, including traditional incandescent bulbs, LED bulbs, and halogen bulbs. Warm white fluorescent CFLs can be a good replacement, but do know that they still emit a small amount of UV rays.

Does CFL 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.

Why are my LED bulbs burning out so fast?

Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.

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.

Is it worth switching to LED bulbs?

In addition to saving money, LEDs can save you time — with fewer trips to the store and up the ladder. They last about 25,000 hours.

Does turning LED lights on and off shorten their life?

The operating life of a light emitting diode (LED) is unaffected by turning it on and off. While lifetime is reduced for fluorescent lamps the more often they are switched on and off, there is no negative effect on LED lifetime. This characteristic gives LEDs several distinct advantages when it comes to operations.

Should I replace CFL with LED?

Yes, LEDs do last longer and use less energy than CFL bulbs. LEDs can also cost a little more, and should provide an ROI within two to four years.

Are LED bulbs safer than CFL?

LEDs use significantly less energy than even CFLs, and do not contain mercury. And they are becoming economically competitive with CFLs at the point of purchase while yielding superior quality lighting and energy bill savings down the line.

What is bad about LED lights?

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. Studies also reveal that light emitted by LEDs can cause retinal changes, if there is high exposure for even a short period of time.

How many lumens do I need?

To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
