LED lamps are often promoted as energy-efficient lighting for both inside the home and outside however experts say that LED lighting, if not installed in moderation, could affect our health; this is because LED lights emit 10% more blue light and CFL lights. LED lighting leads to cost and energy savings and a lower reliance on fossil fuels in incandescent bulbs. An electric current passes through a wire filament until it becomes hot enough to emit light incandescent bulbs, therefore, waste a lot of energy as heat. A LED bulb produces light when positive and negative electrons move around within its semiconductor structure but not all LEDs are good for you.
Some Beneficial Effects of LED Lights
LED lights produce the same amount of light as incandescent or fluorescent bulbs but use less energy or watts this means they produce more lumens per watt. LED bulbs also have a longer rated life on average they will last over 20 years; to put this in perspective if you installed an LED bulb the same day a baby was born the bulb would not need to be replaced until after their college graduation.
Harmful Effects of LED Lighting
To determine if an LED light is good or not you have to know the color temperature. Color temperature is a measure of spectral content how much blue green yellow and red is in a light. A higher color temperature generally means more blue content while an incandescent bulb has a color temperature of 2400 kelvin containing fewer blue and more yellow and red wavelengths. A flame from wood or a candle burning has a color temperature of about 1800 Kelvin mostly yellow and red with almost no blue. Click here.
Blue-Rich LED Lighting
Blue-rich LED lighting can cause discomfort and glare this is because blue light scatters more in the human eye in yellow and red sufficient levels of blue light can damage the retina and LED light is concentrated which can cause severe glare resulting in strained eyes. The American Medical Association also warns the Blue-rich LED light can have a negative impact on the human circadian rhythm. Blue-rich LED light is estimated to be five times more effective at suppressing melatonin at night than the sodium lamps causing sleeplessness. Exposure to this type of light disrupts our body’s ability to produce melatonin a hormone that helps us fall asleep; when this process is disrupted our body’s clock goes off button. Many studies have suggested the blue light emitted by our mobile homes and laptops is destructive because its short wavelength tells our brain to stay a look.
On the other hand low light could be beneficial when it comes from the Sun as it gets diffused in the atmosphere and stimulates the retinal ganglion cells thereby improving the biorhythm. The United States Department of Energy has claimed that LED lights are no more harmful than any other lighting; however, we should ensure that lighting products meet photo-biological safety standards.
