BIO-LOGIC LIGHT: A New Standard for Daylight-Like Lighting

Rethinking Daylight-Like Lighting

How can artificial lighting better support our natural needs? With BIO-LOGIC LIGHT (BLL), LUMITECH and Bartenbach have developed a new approach to Human Centric Lighting that combines scientific knowledge with practical lighting design.

The concept takes natural daylight as its reference. Intensity, color temperature and direct and indirect light components change throughout the day and influence our circadian rhythm. BIO-LOGIC LIGHT brings this dynamic into indoor environments while also considering typical working hours and daily routines.

The technological foundation is LUMITECH’s patented 3-channel PI-LED technology. Its wide color-temperature range of 1,800 to 16,000 K enables precise control of direct and indirect light, helping to address both visual and biological lighting requirements.

The result: a new quality of daylight-like lighting – designed around people and the needs of modern working, learning and living environments.
