LED Streetlights Are More Efficient And Save Money But Might Hurt You.
Many cities got their uniqueness by how they look at night. Could you imagine if New York, Paris or Sidney suddenly lost their signature nighttime scenery?
Nonetheless, today’s technology focus is not on looks, but rather on cutting costs and safety. Even though considered as revolutionary, LED streetlights have shown surprising consequences.
LED lights are considered to save cities funds on power and maintenance. Also, they do allow better and clearer vision at night.
Although the old orange-ish yellow-ish lights seem warmer and more pleasant to some, they sure do not illuminate the streets well as they are suppose to.
Whereas, LED lights provide clearer, cooler night light vision and better illumination. But, the American Medical Association (AMA) issued a warning about them.
In some cities where LED street lights were implemented, people started complaining about the harshness of the lighting.
For example, the city of Davis, California implemented LED lights only to change the project midway because there have been numerous complaints about the new bright lights for causing glare and hurting eyes.
At a certain color temperature (CT), lights can cause eye damage.
The AMA warns that lighting mustn’t exceed a CT above 3000 Kelvin. We’ll put it like this: a candle gives off a CT of about 1800K, while an incandescent bulb has a CT of about 2400K. Some of the LED lights that have been installed around the country have a CT above 4000K. They contain a cool blue wavelength that can scatter when it hits the eye.
Despite making the road seem brighter an clearer, this light can damage the retina. Moreover, brighter light contributes to more light pollution that can throw off people’s sleep rhythms — and animals’ as well, and shake up their migratory patterns.
Not to be gotten wrong, the AMA is pro LED lightning, but they suggest converting to lowest possible emission of blue light when doing so; and shield the LED installations to reduce glare and possible harm.
