We take pleasure in saying that the Prisms have
proved to be a great success in our store, giving us sunlight throughout
the entire room, as well as reducing our light bill about 50 per cent.

I take great pleasure in saying that the Luxfer
Prisms which you made and put in for me are perfectly satisfactory.
Therefore, I take the liberty to write you my opinion of the same. I
know that they are scientifically a correct piece of work, because they
reflect the light just where it is needed. They also turn dark days into
light ones by bringing all of the available to a certain point. They
also serve as a screen with the fact that they prevent any view from the
outside. I can very cheerfully recommend their use by any of the profession
whose light is in any way impaired or obstructed. Yours truly,

Your patent Prismatic lights, which you recently
installed for us to light the basement of one of our buildings, are giving
good satisfaction. The basement, which was formerly quite dark and of no
use except for storage, is now light enough to use over one-half of it for
displaying samples of goods which require exceptionally good light; in
fact, the front half of the basement seems to be as light as the front half
of the store floor, which has modern plate glass windows.

We have used your lighting product in various
ways and places and take pleasure in stating that the results have been
entirely satisfactory to us. Yours respectfully,
