PRISMS.
"Schwickart's Sunburst" Prisms (patented in the United States, Canada, Great Britain and Germany) are ornamental, have a higher artistic appearance than any other construction, and solve the problem of a really efficient sidewalk, vault or ceiling light.
ADVANTAGES.
This prismatic system does not tire the eyes like artificial lights, and the cost of maintenance is practically nothing. The economy of the "Sunburst" Prism System, which we claim to be the best, is due to the superior efficiency of the prisms.
The vertical and quadrilateral diffusion of light is absolutely obtained with these prisms without the aid of crude or ugly devices. Each lens takes care of its own expansion and contraction, and if any prisms or settings should become injured, repairs can easily be made at a minimum of trouble and expense.
The lenses have great strength and beauty, and when used as a skylight the white cement obviates the black spots so noticeable in other systems.
In the use of the "Sunburst" Vault Light the necessity of transparent doors is eliminated, insuring an additional saving in the cost of the doors.
One third of the space required by other systems is sufficient for "Sunburst" Prisms to transmit the same amount of light, and all remaining space around the vault-light panel can be made of reinforced cement.

CONSTRUC-
TION.
The lenses have a plain top surface, set flush in cement, making a water and moisture proof building light. The square bottom portions of the lenses have the sides projecting below the cross-bars which are spaced so that the square bases of the adjacent lenses abut both in a transverse and longitudinal direction, forming an under surface of glass of an unbroken continuity.
The conical bottom portion of each lens has an angular bead which anchors it firmly in position, and the prisms in the lower part of the lens tend to refract

"SUNBURST"
WINDOW
REFLECTOR.
Our new "Sunburst" Prism Reflector Attachment is designed to illuminate dark and dismal offices and apartments, rooms in lower floors of high buildings, rooms lighted by shaft or court, and wherever direct side light can not be obtained.
The Reflector is very ornamental and is attached to the outside face of the wall at top of the window. it is made to fit any size window opening.
The Reflector is made slightly wider than the window, an inch or more on each side of the opening, to allow for fastening to the wall.
The top surface is made of "Sunburst" Prisms 12 inches wide and projecting at right angles to the face of the building. The light direct from above passes through and is then, by the aid of the mirror attachment, received as reflection from the prisms and distributed both vertically and laterally, and penetrates into the room a distance of 40 feet, with the regulation 12-inch top surface of "Sunburst" Prisms, containing four rows of lenses. If the depth of the room exceeds 40 feet an additional row of lenses on the top surface is required, which will cause the reflected light to penetrate 10 feet farther.

REFLECTOR.
The "Sunburst" Prism Vault Light with Reflector attachment is especially valuable for the purpose of lighting basement rooms or cellars. The transmission and diffusion of the light through our prismatic lenses is uniformly and equally effected in all directions. This fact in itself has made our "Sunburst" Reflector possible, and the same result could not be obtained from any other prism lacking this all important quality.
