JACOBS' PENDENT LENS
THE PERFECTION OF ILLUMINATION
We do not claim as other have done,
to give more light than comes through the lens opening, but
we use and diffuse the natural light to the best advantage.
Ordinary bull's eye glasses throw the light directly down,
while Jacobs' Pendent Lens distributes the light all about
the basement or room to be illuminated, as EACH lens is
so constructed as to throw the light in all directions AT
ONCE. Lenses are made to fit any variety of tile, either
cast iron or concrete face.
