Just like mentioned on its cover, this book will tell us a lot about the science of lighting. A guide for people who want to know more and understand more about lighting. It will tell us about light and radiation, how is light produced, how is light directed and screened, about quantities of light and the unit, about light and vision, light with color, about light and health, about lighting quality. The way of this book tell us about the content is easy to follow and understand. Even though it tells a lot about the science (of course include with formulas, calculation, science terms, etc), the writers have done a great job to make the content easy to understand, even for people who just know or newly learn about lighting.
