Abstract :
Obviously it is impossible to prophesy accurately what will happen in any phase of human activity. In the field of lighting, however, it is fairly safe to make some predictions based upon the following hypothesis: Throughout the world there are certain organizations and establishments which are unusually progressive, which do things before the ideas involved have been accepted generally. A study, therefore, of what is being done in these outstanding examples gives an indication of what is likely to become general practice in the next several years. On this basis the author analyzes lighting methods in certain definite fields, such as stores, restaurants, industrial plants, and streets. He describes installations of new types of illuminants and new methods of applying the older forms.
