Oregon 1919 A lighting code was adopted in 1913, but did not contain intensity stipulations. Law provides for board to recommend intensities, which intensities have not yet been announced. States which Have Industrial Lighting Legislation Definitely State Ohio Massachusetts Oklahoma Under Contemplation Comment Very extensive list of intensity recommendations has been prepared. Very extensive list of intensity recommendations has been prepared. Several other States have this subject under advisement. In substantially the form of the Society's latest revision, this Industrial Lighting Code has been further reinforced as to authority and influence by being promulgated by the Committee on Labor of the Advisory Commission of the Council of National Defense and by the United States Bureau of Standards as a part of the Safety Code. In the several States the codes have been adopted and put into effect under the auspices of the State labor authorities. The movement for better industrial lighting, of which these industrial lighting codes are an expression, is of immediate interest to central station companies. Adoption and enforcement of such codes means more useful application of artificial light in the promotion of safety and comfort of workmen and in the promotion of economy in industrial plants, both of which tend to confirm the great value of central station service to the community, and, in enhancing the value of that service, tend to increase the company's business. The enforcement of these codes will result at all times in the improved utilization of artificial light, and in many cases an increase in the amount of light used, with resultant advantages to the workman, to the industrial establishment and to the central station. THE FOOT-CANDLE METER An instrument called the foot-candle meter recently designed and which has been described in the technical press is being used with considerable success in measuring the illumination intensities commonly found in artificial lighting installations. The instrument is simple in operation, so light that it may be carried about, and of such size that reading may be taken in very restricted spaces. Fig. 6 is an illustration of the instrument, while in Fig. 7 the same is shown in operation, being placed upon a lathe for the purpose of measuring the foot-candle intensity on the work. A lamp within the box illuminates the under side of the screen to a much higher intensity at one end than at the other. The illumination which it is desired to measure is, of course, practically uniform over the entire scale. Closely spaced translucent dots, which serve the same purpose as the grease spot in the simple bar photometer, line the scale from end to end. If the illumination on the scale from the outside falls within the measuring limits of the meter (0.05-25 foot-candles) the spots will appear brighter at one end of the scale than at the other, and at the point where the spots are neither brighter nor darker than the white paper scale the illumination from within and from without are equal. The scale is accurately calibrated with the lamp within the box burning at a certain definite voltage. A voltmeter and rheostat permit the operator to adjust the lamp voltage to that at which the instrument was originally calibrated. The energy is supplied from a standard 3-cell flash-light battery. Several of these instruments may be seen in use throughout the Lamp Committee Exhibit. FIG. 7 FUEL CONSERVATION LAMP PROGRAM For the purpose of the record, it will be of interest to outline the conservation program of the United States Fuel Administrator as applied to the production, distribution, and use of lamps. including carbon and gem. This program, the details of which are a matter of record in the Proceedings of this Association, was promulgated by the Fuel Administrator, following a report (made to and adopted by him) of a sub-committee appointed for that purpose, of which Mr. John W. Lieb was Chairman. The details of the recommendations were made public first by the Fuel Administrator in direct communication with all interests involved, through the instrumentality of the Lamp Committee of the Association of Edison Illuminating Companies, the National Committee on Gas and Electric Service, and finally, through our Association, as a result of direct request by the Administrator to your Lamp Committee. Your Committee undertook to bring this to the attention of the membership, through the medium of the BULLETIN and by a direct communication to the Class A members, as follows: To Member Companies: Your careful attention is directed to the current month's issue (Vol. 5, No. 8) of the Association BULLETIN, containing on page 470, in`full, the fuel conservation program promulgated by the United States Fuel Administration, through the discontinuance of manufacture and renewal of certain types and sizes of inefficient incandescent lamps. The Association has been asked by the United States Fuel Administrator to lend its aid in carrying out this program, and at a meeting of the Executive Committee held on Friday, the 13th instant, the Lamp Committee was authorized and directed to bring to the attention of the membership, through the medium of the monthly BULLETIN, the details of this program. Your Committee was also authorized to address a communication directly to member companies calling attention to the September issue of the BULLETIN and asking for a hearty compliance with the provisions of the program therein set forth. Please make a careful study of the recommendations made by the Fuel Administrator, and, so far as the same refers to central station companies, undertake to comply therewith in every respect possible. It is urged that the widest publicity be given the matter either in the daily papers, house organs, or other advertising media, and through your sales organization to make the program thoroughly effective. Your Committee would greatly appreciate it if you would advise what steps your company will take toward this end, putting us in possession of copies of all advertisements or other data that you may publish or issue on this subject.
