 O

Order
 Shorthand expression of the size of an optical apparatus or lantern. At the time the system of  orders was established, when kerosene burners  were used, longer range lights needed larger  burners, and larger burners needed lens assemblies of longer focal length to ensure a sharply defined beam. In turn the lantern rooms were required to
 be larger to house these lens assemblies. AMSA historic lantern rooms range from 1st to 4th order.

 P

Pedestal
 Part of the optical apparatus, consisting of a metal column or base standing on the balcony floor inside the lantern and supporting the lens assembly and light source. Some later Chance documentation
 ,such as their tariffs 1908, also refer to the lantern
 base as a pedestal.

 T

Tower
 Structure to support the lantern at a sufficient height
 above the ground. The most common types are the masonry tower, timber-framed tower, cast iron tower, and lattice tower.
