It gives us pleasure to express our appreciation
of the improved conditions within our salesroom since the installation of
your product. Having a somewhat long front, and not very deep rooms, we
have always considered ourselves reasonably well provided with light, but
your Prisms have effected a most remarkable improvement. The result has
been to very substantially reduce the amount of artificial light in use,
and to give us one of the brightest and most comfortable salesrooms in
Very truly yours,
