Book Description
Excerpt from Incandescent Electric Lamps and Their Application Since the advent of the carbon filament incandescent lamp so many wonderful discoveries have been made that the adoption of the electric glow lamp as an illuminant is now almost universal. A little thought will establish the fact, however, that the improvements made have been chiefly in the lamp itself, the introduction of the metal filament being responsible for the increased efficiency that has placed electric lighting practically within reach of all. In comparison with the advances made in filament construction those made in the direction of scientific artificial lighting have been small. The formation of the Illuminating Engineering Society has done much to create an interest in this important subject, while further, the work of Government Commissions and the publication of their reports on school, factory and library lighting has served still more to impress people with the importance of adequate illumination. If good lighting is important in public institutions it is equally if not more important in the home, and the approved methods of disposing of the light units so as to avoid unnecessary glare and produce an adequate illumination, as well as the judicious selection of wall and ceiling coverings, should be fully understood by all users and installers of electric light. The existing literature on the subject is of too scientific and technical a character for other than scientists, and in presenting this treatise the author hopes that the obvious gap may be filled and that the general reader may be assisted in deciding upon the most suitable candle-power and distribution in his own particular case. The author has to thank Messrs. Siemens Bros, for information concerning tantalum and permission to reproduce one of their diagrams; Messrs. The General Electric Co. for information concerning the drawing down of tungsten filaments; Messrs. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
