The street lights will not induce miscarriages in pregnant women, or cause insomnia, or nosebleeds, and they are not killing all the birds and insects.A spokesman also said that the authority had spoke to Public Health England about the trancievers on its streetlights and experts had confirmed there was “no risk”.
Are LED streetlights safe?
Despite the energy efficiency benefits, some LED lights are harmful when used as street lighting, its website reads. It explains that while the lights appear white to the human eye, they are actually blue, which can make nighttime glares more harsh for eyes and can lead to discomfort.
What is the problem with LED street lights?
The first is discomfort and glare. Because LED light is so concentrated and has high blue content, it can cause severe glare, resulting in pupillary constriction in the eyes. Blue light scatters more in the human eye than the longer wavelengths of yellow and red, and sufficient levels can damage the retina.
Are LED streetlights better?
LEDs are up to 50 percent more energy efficient than traditional sodium bulbs and can last 15 to 20 years. And there are other unexpected benefits. Better street lighting could potentially make riding public transportation easier by reducing the perception of danger, as well as improving visibility on roads.
What color temperature are LED street lights?
Lower temperatures are warmer and yellower; higher temperatures are cooler and bluer. Our existing high pressure sodium (HPS) streetlights have a color temperature of 2200K. LED streetlights have color temperatures ranging from 3000K or lower (warm white) to 6000K (day white).
How long do LED streetlights last?
Long and predictable lifetime: The projected lifetime of LED street lights is usually 10 to 15 years, two to four times the life of currently prevalent HPS.
Why are there purple street lights?
The purple hues are not intentional. They’re caused by defective LED lights, and crews need your help replacing them. Duke Energy officials say normal LED lights give off no color. But a small percentage of the area’s tens of thousands of street lights are casting purple shades due to a manufacturer’s defect.
Do LED lights emit electromagnetic radiation?
Unlike other energy-efficient types of lighting, the LED bulb does not emit polluting radiation and therefore does not pose a health hazard.LED lighting also does not emit UV or infrared radiation, it does not contain mercury and is resistant to shocks and vibration even in a particularly cold environment.
Which is the best LED street light?

What are blue street lights for?
LED lights normally have a blue / violet color. Turns out it’s the covering that has worn off and needs to be replaced. The coating is supposed to turn that blue’ish or purple’ish light to a bright white so you can see better.
Do street lights make safer?
There is no clear scientific evidence that increased outdoor lighting deters crimes. It may make us feel safer, but has not been shown to make us safer. A 2015 study published in the Journal of Epidemiology and Community Health found that streetlights don’t prevent accidents or crime, but do cost a lot of money.
Why are there purple street lights in Florida?
TAMPA, Fla.
– Street lights around Tampa usually illuminate a bright white color, but some purple lights are popping up across the city due to a manufacturer’s defect.”It’s happening at multiple utilities across the country to multiple manufacturers of these lights, and it is a manufacturing defect.
Are LEDs more efficient than HPS?
LEDs are much the same. Though they’re generally more efficient than HPS (with some clocking 2.8 µmol/joule), some LEDs are less efficient than high-quality HPS fixtures, and they give you less light.
Can I complain about street lights?
If nearby street lighting is shining in to your home at night and causing you distress, you can contact your local council’s street lighting department, explain the problem you are having, and ask what they can do to minimise the problem.
Can street lights be too bright?
When street lights are too bright they can cause light pollution, something that delays the maturity of crops, aggravates astronomers, and disorients wildlife like sea turtle hatchlings, which can wander inland instead of toward the sea, where they end up dying after being run over by cars or eaten by predators.
Why are street lights white?
The different colors of the lights are caused by their use of different light generation techniques. The history of electric street lighting first used incandescent lamps, then mercury-vapor lamps (white color), then sodium-vapor lamps (yellow color) and recently LED lamps (white color).
What are the advantages and disadvantages of using LED light as street light?
It can be used for more than 50,000 hours and provides three-year quality assurance. But the disadvantage is that the battery life cannot be guaranteed. 8. Using chips ?100LM, LED street light can save more than 75% of energy compared with traditional high pressure sodium lamps.
How powerful is a street light?
A high-pressure sodium street light can draw up to 1000 watts, and an incandescent light used in the 1900s needed 320 watts. Some LED street lights require only 73 watts and, according to the U. S. Department of Energy, produce a higher quality of light.
Are LED streetlights brighter?
The result is that at night the blue-rich light from an LED streetlamp looks brighter to the eye than the orangish light from a high-pressure sodium lampeven if the two emit the same number of lumens, which are measured on a scale based on the eyes’ daytime response.
Why are street lights orange?
Streetlights and industrial lights, such as those found in parking garages or manufacturing facilities, give off a yellowish or orange glow because they are sodium vapor gas-discharge lights. There are two types of sodium vapor lights, high pressure (HPS) and low pressure (LPS).
Can LED lights turn purple?
White LED light is made up of all of the colors in the rainbow, when one color is removed, such as green, it leaves red and blue light which mix and make purple. Bowling Green Municipal Utilities’ Christy Twyman says she’s not exactly sure what caused the manufacturing error.
