Vault Lighting and How It Is Secured |
|
The proper lighting
of basements and subsidewalk space depends largely on
the use of the correct form of glass. To meet every
possible condition and to satisfy all ideas in regard
to the best type of glass to use, we make out sidewalk
and skylight tiles in many different forms and sizes.
|
We are thus able to solve every every lighting
problem in the most effective manner. For size and number
of each, look under the headings of the different forms
of constructions.
PLAIN LENS, round or square. For lighting the
space immediately below the setting. An efficient form
when the space to be illuminated is not large, for the
light rays drop down.
SINGLE PENDANT PRISM, round or square. For
throwing the light to spaces outside the range of
the Plain Lens. The large single prism throws a
strong single beam of light in one direction only.
It has the advantage over the plain lens in that it
illuminates a larger area but, because of its weight
the cost is considerably more.
MULTI PRISM, square only. For general diffusion
and the breaking up of the direct light rays. Preferred,
by some, to the plain lens for this reason.

3-Way Prism |
 |
3-WAY PRISM, square only. For
spreading the light rays over a large area and
illuminating the largest amount of space. Each of
the three prisms on the tile are of a different size
and of a different angle. Thus the light is thrown
in three separate beams to the various parts of the
room. Probably the most efficient form of tile because
it gives a wider range to the light equalized over
a large area.
|
All of our glass is made of a special
tough composition that resists wear and pressure so
that danger from breakage is reduced to a minimum.
The trademark  is moulded
in every tile. Be sure to specify .
