Lighting is hands down the most “visible” and universal technology humans are exposed to in the built environment. While energy savings often initiate the discussion to switch to LEDs, lighting can deliver far more than just light and energy savings. The growth of human-centric lighting over the past 8 years has led to an increasing focus on the visual and non-visual effects of light. From alleviating headaches through flicker-free lighting to improving sleep quality through circadian lighting, advanced lighting systems can provide more amicable and productive environments.
