Vault Lights

The History of Sidewalk Pavement Lights

Prior to their use in city sidewalks, vault lights first appeared in 1845 as a way to provide light below deck on ships. Invented by Thaddeus Hyatt, they reduced the use of open-flame lighting that had the potential to create treacherous problems on old wooden ships. A brilliant way to light lower levels, their application spread to sidewalks in order to bring natural lighting to subterranean rooms, storage, apartments, and basements below.

From 1860 until the widespread use of electricity in the 1930s, vault lights were used across the country to convert dark spaces into usable rooms by bringing in daylight. The first design of vault lights featured a prism shape to maximize the spread of light into the room below.  Multiple prisms were configured to cover wider areas and mounted into cast-iron panels and concrete.

The Vault Light Evolution

Today, we see a resurgence in the use of vault lights as the benefit and sustainability of natural light is embraced by architects and designers.

The design and materials have all evolved to improve durability. These modern vault lights also feature a larger surface area, which aids in increasing the transfer of light. The early sidewalk prisms have been replaced by circular bullet glass and square vault lights.  During the day, natural light shines in, creating warmth. At night, the lighted sidewalk vault creates a dramatic entrance and a stunning feature of modern architecture.

Vault Lights and Historic Charm

Vault Lights Restored & Reimagined

Innovation in materials used in structural glass applications is extending the benefit of vault lights to new applications. Structural glass can now be found in walkable skylights, glass bridges, decks, balconies, landings, risers, and stair treads.

As well as new applications, innovative architects are making the old new again through the use of the historic aesthetic of vault lights cast in composite concrete or cast iron frames, which can be used for walls and ceilings.  Prefabricated panels can be custom-engineered to achieve the architect’s vision. Built to withstand structural loading requirements, the design can incorporate different glass shapes, textures, and colors. Steel, stainless steel, and cast iron pavement lights are available in a variety of finishes and colors too.
