The latest ideas in illumination

The first meeting of the New York Electrical Society for the administrative year 1924–25 promises to be unusually interesting. The Director of the Lighting Research Laboratory, National Lamp Works, Cleveland, Mr. Luckiesh, will explain some of the very latest ideas that have been developed in the illuminating field. He will show among other things how artificial lighting has not kept pace with its rapidly decreasing cost and the increasing standards of living, prove daylighting indoors costs as much as artificial lighting and is less satisfactory and will discuss the quality of light with relation to the human being from several viewpoints. In connection with new data on the effect of quantity of light on our ability to see he intends to show that the most effective intensities are many times those with which we are ordinarily familiar in artificial lighting. Mr. Luckiesh will accompany his talks by interesting demonstrations and will test the speed of vision of the audience. This is believed to be the first time such a test has been attempted. Engineers interested are cordially invited to attend. The meeting will be held in the Auditorium, Engineering Societies Bldg., 33 West 39th St., New York at 8 p. m. on Thursday, October 23, 1924.
