Semi-Prism Glass Co,
The Rookery, Chicago.
Gentlemen:
I have made a thorough examination of the
Prismatic glass manufactured by you, and am convinced of its merit
for the purpose for which it is designed. By its use, large savings
in the cost of artificial light will be made, resulting in better
illumination of shops, offices, manufactories, etc., than has
hitherto existed.
I should think this product will be of value
not only in old buildings but in new ones as well.
Yours very truly,
ION SPECIALTY COMPANY,
58½ Yonge Street.

Luxfer Prism Co., Limited, Toronto.
Gentlemen:
Our sample room is long and narrow, the dimensions
being 15 feet wide by 100 feet deep. The Prisms installed in the front
window diffuse a good light to the extreme rear of the sample room, through
a screen partition 60 feet from the front and to the rear of a back room, in
all 100 feet from the front window. The Prisms, being hung on hinges can be
removed, and in this way the comparison between the difference in conditions
of light with and without Luxfer Prisms can be seen. Without Prisms this
sample room is dark and useless as a salesroom. With Prisms, we have all
the light we desire for business purposes. We would not rent our premises
without the Prisms, unless the light could be otherwise improved.
Yours truly,
ION SPECIALTY COMPANY, Limited.
J. W. Lester, Treasurer.

Gentlemen:
Regarding the Luxfer Prisms which you have placed
over our dining room window, we would say that we are astonished as well
as pleased with the change you have made in this room. Before we had the
Prisms our room was so dark that we frequently used gas, not only in the
morning and evening, but on rainy or cloudy days, but now we do not use
gas at all in this room in the daytime. Of course, we enjoy having daylight
in place of artificial light very much, and take pleasure in saying that we
are satisfied in every way with the Luxfer Prisms.
Very truly,
