Despite of the fact that LED streetlights are more efficient and save money, they can hurt you.
A lot of cities got their uniqueness by how they look at night. Can you imagine New York, Paris or Sidney with a normal lighting?
But, nowadays technology is not focused on looks, but rather on cutting costs and safety. However, it turns out that LED streetlights have shown surprising consequences.
It is believed that LED lights will save city funds on power and maintenance. Also, they change the appearance of cities and allow for better, clearer vision at night.
Even though, 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 supposed to.
On the other hand, LED lights provide greater illumination with cooler night light. However, the American Medical Association (AMA) warns about them.
A lot of people complain about the harshness of the lighting. That happens in some cities where LED street lights were implemented.
For instance, the city of Davis, California started changing over its streetlights to LED, as there have been a lot of complaints about the new bright lights for causing glare and hurting eyes.
The lights can lead to eye damage, at a certain color temperature (CT).
According to the AMA, lighting must not exceed a CT above 3000 Kelvin. We will explain this more clearly: a candle gives off a CT of about 1800K, while an incandescent bulb has a CT of about 2400K. Many of the LED lights being installed around the country have a CT above 4000K. They consist of a cool blue wavelength that can scatter when it hits the eye.
Thus, although the roads seem brighter and clearer, this light can actually damage the retina. Additionally, it should be known that the bright lights contribute to more light pollution, so that they can throw off people’s sleep rhythms, and animals’ as well, and shake up their migratory patterns.
The AMA made a few recommendations: converting to LED lighting; but, using the lowest possible emission of blue light when doing so; and protect the LED installations to reduce glare and possible harm.
