Warm white LED street lights and parking lot lights—with a CCT of 3000K or less—are a much better option for public outdoor areas. They emit a much smaller portion of blue light—which is unnoticeable to the eye—and are currently the best options available for street lighting.
How do I choose an LED street light?
The height of the streetlight pole will determine the wattage of the bulb that you should buy. If the height of the pole is not more than 12 feet, buy an LED bulb whose wattage does not exceed 15 watts. For poles between 12 to 15 foot, buy a bulb whose wattage ranges between 15 and 30 watts.

Do street lights have bulbs?
It turns out that bulbs found in streetlights aren't like the bulbs in our regular table lamps or light fixtures at all. Since there's no finicky filament to decide when the bulb's life is over, streetlights last much, much longer than traditional incandescent light bulbs.It turns out that bulbs found in streetlights aren't like the bulbs in our regular table lamps or light fixtures at all.

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.
Which light is good for eyes tube light or LED light?
Traditional incandescent bulbs are fine, but many people are looking for a more energy efficient option. Luckily, “warm light” CFLs (Compact Fluorescent Lights) are okay for your eyes, as well as being much more efficient. They do emit UV rays, but a much smaller amount. You can also use LED bulbs or halogens.
