My title may be questionable but this is the warning label: this is not aimed at LED enthusiasts, infact i don't mind LED at all, it is aimed at people who are ignorant in terms of lighting technologies, such as this person who made broad claims in this youtube comments section https://www.youtube.com/watch?v=LJHLopzGz3Q i don't usually argue, but for some reason i felt the need to right some misinformation

There is no comparison. LED street lights are superior in every way. The quality of light is far better - they provide sharp true color just like daylight from the sun - the way we have evolved to see. They direct the light straight onto the street with no dangerous side glare and light pollution. They use much less energy than other lighting technologies and last far longer. I have been rejoicing that they have replaced the dangerous ugly glaring HPS lights in SLO with quality superior LEDs.

They can still cause light pollution, by the same effect that the suns light reflects off the moon, the moon is not white by the way, it is grey, much like the pavement of roads or atleast the older roads that have not been repaved which is most, I'll have you know there is HPS fixtures with optics that focus light downward exactly like these LED's you speak of, also you say they're dangerous for their glare? you realize that these things re mounted up high, so realistically there will be side glare no matter what light source it is, therefore that argument is invalid, also they are not the most efficient light source, Low pressure sodium (LPS/SOX) has reach efficiencies of up to 200Lm per watt, which still is higher than any available LED as of yet. and yes humans are evolved to see similar light to sunlight, but you don't need sunlight for traveling on a road, nor do you necessarily need high colour visibility, infact HUMANS DID NOT EVOLVE TO SEE THE SUN AT NIGHT! it is much more beneficial to have dimmer lights at night, to both humans and the environment, i might also add that the lack of color forces you to see certain details better since your eyes/brain are forced to adapt to their loss of ability to see colour information, and currently they do not last longer than ALL other lighting technologies, one technology that has been proven to last a long long time, and by long i mean decades is the mercury vapour lamp, which some have been burning bright for as long as 60 years, LED has not had the time to prove itself like this, therefore you cannot claim they last longer than ALL other lighting technologies


the guy will likely never see this unless he has notifications for comment replies turned on, but i still felt the need.
