vault light การใช้

But anyone can venture into City Hall Park, just southwest of City Hall, to one of the original vault light panels.
The first floor ( at track level ) featured a large waiting room occupying the entire center block, with vault lights providing natural illumination and a fountain set into the western wall.
Deadlights were commonplace for lighting underground vaults in the 19th century, in which application they were also called " vault lights " ( US ) or " pavement lights " ( UK ).
Along the platform, 12 chandeliers lit the space, along with nine fanciful leaded-glass skylights, which brought light down from panels of vault lights above, a luxury of the early subway that originally extended systemwide.
