Metro's original brutalist vaults were intended by their designer, Harry Weese, to be blank and to be lit entirely by indirect lighting. However, over the years, accoutrement has been added to the vaults, from station signs to security cameras. In most stations, supplemental lighting was added in mezzanines, which tend to be in perpetual shadow.

The new test lighting strikes a medium between the extremes. It adds lots of light to the mezzanines, while still providing light to the vault. At the same time, the fixtures' design limits the encroachment of the light supports on the vault.
