This webinar will provide 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 will also be 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.


  • Introduction to fundamental concepts of LED lighting technology
  • LED lighting colour temperature
  • Health impact of colour temperature  
  • Questions and answers

Learning Objectives

  • Understand basic concepts of LED lighting technology
  • Understand colour temperature of LED lighting source
  • Identify benefits and potential issues of LED street lighting

Target Audience

Lighting designers, engineers, owners and operators of the roadway lighting systems
