Street lighting is designed to illuminate roadways, streets and adjacent areas to enhance safety for drivers and pedestrians. Legacy street lighting systems typically use high pressure discharge lamps, in most cases high pressure sodium (HPS) and metal halide lamps. These light sources used to be recognized to give the highest amount of lighting per watt of electricity used. As natural resources and energy will be depleted eventually, it gets to be important to save fossil energy and develop new everlasting energy. Because of this, people throughout the world are making efforts in this direction for public constructions. The demand for energy-efficient LED Street Light is driven by energy efficiency and various other factors including enhanced product life, lower maintenance costs, and reduced environmental impact.
Ignorant Preference with Color Temperature
There's a widespread application of outdoor lighting that incorporates cool white CCT (correlated color temperatures) light sources because of the ignorant preference in the perceived feel of "cooler" or "whiter". In countries with low latitudes the climate is hot and people prefer lights with high color temperatures which bring them a cool feel. The dominance of fluorescent lamps in the past few decades has made some people accustomed to the cool whiteness of lighting. They believe "whiter" the light "clearer" the visibility. However, in the area of LED lighting should people still make their choices based on how they feel? Never again! On June 14, 2016 the American Medical Association (AMA) released an official policy statement about led street light. They expressed serious concerns on the detrimental effects of high-intensity LED lighting.
