What does color temperature mean?

Color temperature of lighting is measured in Kelvin (K) units. When LED streetlights first came out most applications used 5,000 Kelvin, very cool or white. These were very harsh and almost bluish. Applications then moved to using 4,000K which is called “moonlight.” Several credible sources have issued opinions about the detrimental effects of 4,000K lighting, regarding its negative affect on human sleep patterns, nocturnal animal behavior, and light pollution. The Town has chosen 3,000 kelvin LED lights due to its softened yet effective color.
