But - it offers a very good guide to the real-world contraints and demands of lighting. The author give very concrete and useful suggestions and advice. Analysing a complete design ('Hokey') step-by-step is a clever move. It is also the perfect book for those who want learn how to accurately document their designs to last nut and bolt. Even with my 20+ years in lighting and lighting design, I found this book a worthwhile addition to my collection of lighting textbooks.
