LED lights vs. conventional bulbs: spot the differences

Korea is replacing street lights with LED lights: the aim of this programme is to reduce the electricity bill and light pollution. LEDs require 10 times less energy to generate light, offering a less light dispersion in the air. In public areas where lights have been changed to LED, the inhabitants can see the stars in the sky, because LED lights emit a focused light directed downwards.
This picture, posted by the Reddit’s user alreadytakenusername, shows the significant difference between the two sources of light. LED lights are more eco-efficient and sustainable, and they illuminate roads in a better way, improving road safety.
About one-third of a municipality’s electrical costs are for street lighting, Forbes’ research shows.
As regards LEDs efficiency, producers’ data show that LED lights exceeded 100lm/W: LED lights moved from 180W to over 18,000 lm.
LED lights are economical, clear, less impacting and more eco-efficient lights.
