Print on Demand. This book is among the earliest publications on the scientific and practical application of lighting to interior spaces. Written at the turn of the century, it shines a light on the history of lighting, its impact, and the considerable scientific research that went into making artificial light more efficient and less harmful to the human eye. Illustrated with drawings and photographs from the early 1900s, the book explores the relationship between humans and light, the challenges of using artificial light at the time, the detrimental effects of glare, and the many ways to effectively use reectors, shades, and globes to minimize visual strain and enhance the practicality of artificial light. Beyond highlighting the science behind effective lighting, the book also explores how lighting impacts the aesthetics of a space and provides examples of different lighting applications in various environments. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

Before going into the details of the various points involved in artificial lighting, a short statement of some of the principal reasons why present attempts at efficient illumination are so often found faulty will aid to an understanding of the subject.
One reason why much light is wasted is that frequently too much of the light goes in directions where it is not needed and too little in directions where it is needed. If light coming from a lamp were a tangible thing, as, for example, water coming from a hose, failure to direct it where needed would be more apparent than it is. No one would think of trying to wash windows, flush off pavements or do similar work calling for a concentrated stream of water with a hose fitted with a lawn sprinkler which throws a gentle spray in all directions. Nor would one think of using a nozzle giving a powerful stream on a flower bed or a soft, newly-made lawn. The light thrown in different directions around a lamp can be modified with globes and reflectors just as the direction and character of a stream of water issuing from a hose can be modified bv the nozzle. The important point is to pick the right kind of nozzle and the right kind of reflector or globe for the particular work in hand. Although a certain amount of light on ceilings and walls is a good thing,it is quite likely to be the case that a much larger proportion of the total light goes in those directions than is at all necessary, while a smaller proportion than is necessary is thrown in places where it can be utilized. On the other hand, there are cases where the reverse of this is true.
It is of first importance to know what effects various reflectors, shades and globes will produce. Much attention is therefore given to this in following chapters.

A cancellation, however, is a manual, multi-step request that must pass through several systems. By the time such a request reaches the appropriate stage, the book has almost always been printed, packed, or already dispatched, which makes cancellation impossible.
For this reason, we kindly ask that you double-check the title, edition, and your shipping details before placing an order.
If you change your mind after ordering, you are welcome to return the book once it arrives, and a refund will be issued in accordance with AbeBooks’ return policy.
