Our bodies work through the same cycle every day. Our internal clock determines sleeping and waking phases, as well as heartbeats, blood pressure and mood – a rhythm of biological processes controlled and supported by light, as well as hormones, specifically cortisol and melatonin. A lack of light throughout the course of the day can result in chronic fatigue, sleep disorders or depression.

VTL (Visual Timing Light) “controls” smart lighting in the office by working in tandem with the body's natural endorphins. The Waldmann Net Module facilitates biodynamic lighting by controlling color-changing VTL fixtures. This innovative light management system brings the dynamics of natural daylight into the building to extend the emotional and ergonomic benefits of light quality. Biodynamic light (Human Centric Lighting) can provide lasting well-being for employees in offices with insufficient daylight and also during the winter months when there are much fewer sunny days.
