The Southwark is a traditional, eight paneled, copper lantern and is based on similar, original, The Southwark lanterns located around the Tower of London. The lantern is hand crafted from copper with an access door for re-lamping and the gear integrally housed within the lid. The Southwark is a robust lantern as the frame structure is strengthened with stainless steel inserts. The lantern is available with an optional door or a hinged lid for re-lamping. The lantern is frog mounted as standard; designed to fit a 76mm spigot.

All gear is class I wired and a full range of discharge gear can be accommodated integrally within the lantern. The Sugg twin beam optic can be fitted offering superior lighting performance; this lantern will also take a glass refractor. Single and two part electronic photocells are available as standard and should be factory fitted to maintain IP integrity.
