| This installation of American 3-Way Luxfer Prism Co vault lights at a 1919 building in Tijuana, Mexico, were taken and donated by Ruben Michel Murillo. He reports the building was an elementary, junior and high school, then a state university, and finally Tijuana's Casa de la Cultura. | ||

These are the later-style lights that overcame the two major defects of the original embedded-directly-in-concrete kind—liability to fracture due to compressive forces, and difficulty of replacing lenses—using the same mechanism: the glass lens sits inside and is protected by a cast iron cup. The cup takes the compressive forces, and the lens is only caulked into the cup where it is isolated from stresses and can be easily removed and replaced. "In this construction, the glass—both square lenses and round lenses—is armored against both expansion pressure and the assaults of traffic. Each lens is caulked with tar and brimstone compound in a cast iron galvanized ring, or bottomless cup. This is built right into the concrete slab, being perfectly embedded with a permanent bond." —Sweet's, 1927-28 |
