LED Lights Help In Decreasing Light Pollution

Take a look at the picture on the left. The sky bears an unnatural shade of yellow, caused by too much artificial light. That is light pollution in its finest – light clutter, glare, energy waste, and decreased night visibility.
We have talked about scrolling LED signs and its many benefits. These LED signs are made of LED lights. What benefits are there if we replace conventional lights with LED lights?
LEDs emit light in a more directional way compared to other light sources.  LED lights that direct all their output in one direction are more economical than either LPS or HPS lamps. Aside from its low maintenance cost, LED lights can be dimmed if the light requirement is also less, saving more energy and decreasing light pollution.  As LED signs can still be viewed clearly from the distance because of fewer glares, it goes the same with LED lightings. With more unvarying levels of light, hot spots and dark spots are greatly reduced.
These LED lights, if grouped together, provide light to a particular area of a street or a city during nighttime. What’s good about these is that it doesn’t have to warm up for a few seconds. It comes on instantly the minute you switch it on, therefore reducing wastage.

Now let’s move on to energy wastage caused by light pollution.
With about 35 million streetlights in the US alone that uses conventional lights, it shows that there is a whopping $958,125,000 electricity wastage! 
These lights, compared to LEDs, does not only waste electricity big time but also damages clarity of vision. Light that is not directed downwards strikes the eyes horizontally, resulting in increased glare and reduced vision. Hence, there more accidents waiting to happen.
The rise in LED light usage and the replacement of conventional light bulbs on streetlights and buildings contributes to the elimination of light pollution.  With its high lumen per watt consumed, zero wastage, no toxic waste or mercury, directional lighting, longer life, low cost, low energy consumption, and better performance in cold weather, LED lighting is dominating the lighting technology.
And, oh! LED signs are dominating the advertising industry as well.
