"Bad lighting makes a person unhappy" – this was once said by the German industrial design artist Ingo Maurer (1932–2019), who was also called the Poet of Light. Ingo Maurer's idea has more than once been strongly confirmed in the studies conducted by various scientists.

The influence of light on human health should not be underestimated. Low-quality lighting has a negative effect on our vision, causes overwork, discomfort, headaches and insomnia for more sensitive people, as well as significantly reduces work capacity. Also, lighting performs another important function - it affects human biorhythms. It's no secret that human activity is much higher in natural light than in artificial light, and that our productivity increases significantly on sunny days compared to cloudy days.

Let's not forget that we perceive 90% of the information about the world around us with the help of vision, so it can be safely said that a correctly planned and rational lighting plan plays a decisive role in any area of our life.
