This book is a comprehensive guide to the theory and practice of lighting. Covering the physics of light production, light sources, circuits and a wide variety of lighting applications, it is both suitable as a detailed textbook and as thoroughly practical guide for practising lighting engineers. This fourth edition of Lamps and Lighting has been completely updated with new chapters on the latest lamp technology and applications. The editors ahve called upon a wide range of expertise and as a result many sections have been broadened to include both European and US practice. The book begins with a description of the fundamentals of light, vision, colour and measurement. Part II, the main section of the book, deals with lamps and control equipment and includes descriptions of all lamp types in use today. Part III on lighting covers both interior and exterior applications.

Rare gas resonance lamps having high spectral purity, high intensity, and long lifetimes have successfully been manufactured. The design and filling procedure for these lamps is described in detail. Particular operational characteristics of the xenon, krypton, argon, neon, and helium resonance lamps are also given. Windows suitable for use with each of these lamps are described, with particular emphasis given to the procedure for fabricating thin aluminum windows for use with neon and helium lamps. In addition, a method for determining extinction coefficients and ionization quantum yields based on the measurement of saturation ion currents is described.

In the collection of the J. Paul Getty Museum are more than six hundred ancient lamps that span the sixth century BCE to the seventh century CE, most from the Roman Imperial period and largely created in Asia Minor or North Africa. These lamps have much to reveal about life, religion, pottery, and trade in the ancient Graeco-Roman world. Most of the Museum’s lamps have never before been published, and this extensive typological catalogue will thus be an invaluable scholarly resource for art historians, archaeologists, and those interested in the ancient world. Reflecting the Getty's commitment to open content, Ancient Lamps in the J. Paul Getty Museum is available online at http://www.getty.edu/publications/ancientlamps and may be downloaded free of charge in multiple formats, including PDF, MOBI/Kindle, and EPUB, and features zoomable images and multiple views of every lamp, an interactive map drawn from the Ancient World Mapping Center, and bibliographic references. For readers who wish to have a bound reference copy, a paperback edition has been made available for sale.

This volume illustrates lamps from the Byzantine period excavated in the Holy Land and demonstrates the extent of their development since the first enclosing/capturing of light (fire) within a portable man-made vessel.
