This paper describes the results of laboratory tests of lamps and light quality in terms of, inter alia, consumed principal energy and obtained quality and quality of light, and it quatifies the differences between a number of generic types of lamps. Moreover, it identifies other factors equally important in establishing lighting conditions in a house - room such as the quality of the lamp itself. Electric lighting is shown to be better than non - electric lighting from nearly all points of view; as a matter of fact, electric lamps and non - electric lamps are not directly comparable from the lighting point of view.
