Lighting design has undergone a major transformation with the rise of LED technology. Alongside the upcoming revision of the ISO/CIE 8995-1 standard, the German standard DIN 5031-100 is also being introduced into practice, systematically addressing the biological effects of light on humans for the first time. Lighting is no longer assessed only by intensity on the work surface, color, or glare, but increasingly by the signals it sends to the human body.
New metrics are therefore entering lighting design, such as melanopic lux (m-EDI), which describes the effect of light on circadian rhythm, alertness, and concentration. These principles are already reflected in building certifications such as WELL, BREEAM, and LEED, and are gradually becoming a key attribute and standard of indoor environmental quality.
At Spectrasol, we have therefore prepared a practical guide to new standards for healthy interior lighting, which clearly explains updates in ISO, DIN, and international recommendations, and shows how to prepare projects for them today.
