It afford me pleasure to testify to the
marvelous change in the lighting of this store by the Luxfer Prism
front, put in by you last June.
It is practically a transformation from
semi-darkness to brightest sunlight. In fact, when the sun is in
the east, we have to protect ourselves with shades from the great
glare which penetrates to the farthest recesses of the store.
Your invention is wonderful, and will
revolutionize the lighting of stores and offices in large cities
where streets are narrow and buildings are high, shutting out the
