  • "SOLAR PRISM LIGHT. For many years the inhabitants of crowded cities, particularly in the business portions, have cried for more sunlight and have cried in vain, because it has only been until quite recently that the need could be supplied. Solar prisms have solved the problem for the dark interiors of our public and office buildings, for, by their use, according to the statement of Prof. Charles E. Norton of the Massachusetts Institute of Technology in his recent report on a series of tests, under certain conditions, the light in a room may be increased fifty times by the installation of prisms. The installation of solar prisms has often effected a saving in lighting cost amounting to 100 per cent per annum on the cost of the installation. Under average conditions the direct light from the sky entering a room through sheet or plate glass strikes the floor within a few feet of the window and is mostly absorbed. For this reason the rear part of the room is dark. By the installation of solar prisms at the window openings the direction of the entering light is changed and projected horizontally into the room. Solar prisms do not create light; they simply distribute and diffuse the excess of light at the window. A 12-page booklet fully describing the advantages of solar prisms can be had by addressing Jones & Le Baron, 625 Sixth Ave., New York City." —Municipal Journal & Public Works, 1902
