Why this matters

Practical work and the designer perspective

Good design must not only look good on paper, but also work in everyday life.

This book is written for readers who want to understand lighting beyond individual lamps.

Janne's aim is to provide practical knowledge that helps create spaces that are safer, more functional and more comfortable to live in.
