LED lighting is one of the fastest technology shifts from the 19th century to the 21st. The steady switch to LEDs could reduce lighting power demand and its cost by a significant amount in the world.

This book puts less emphasis on applied science and more on the entrepreneurs who have aimed to take cheap, powerful light-emitting diodes and turn them into successful sources of illumination. In short, the book is about innovation: how human beings take risks to bring good ideas to the rest of us.

The book is divided into three parts. The first part concerns evolution, the quest to build better light bulbs. The second part looks beyond bulbs—the other forms of solid state lighting. The third part concerns revolution, the charting of new territory. It shows how LEDs are initiating another revolution—in the spheres of health and brain function. Further, the author predicts that the lighting will become, among other things, digital, personal, wireless, networked, smart, tunable, and capable of far more than mere illumination. This well-researched book is recommended to everyone.
