This webinar provided information about the colour temperature and health impact of LEDs based on recent research. A review of spectral content and melonopic lux for various colour temperatures was also discussed. A number of jurisdictions that own and operate street lighting systems have chosen energy-efficient LED technology to reduce energy consumption and protect the environment. LEDs have a longer life span and improved physical robustness over incandescent light sources. However, there have been concerns and issues about the health impact of LED lighting due to its colour temperature.
