G.E.C. "Tunbridge Wells" Street Lighting Lantern

Totally enclosed dust-proof lantern specially designed for OSIRA lamps. Constructed of heavy gauge copper with internal stiffening ribs and provided with hinged bottom panel to give access for cleaning and re-lamping. The lantern is supplied completed with porcelain enamelled inner reflector and two special prismatic glass plate refractors to suit the light distribution of the OSIRA lamp. The lantenr is glazed with spreader glasses which give, in conjunction with the plate refractors, an asymmetric light distribution producing high and even road brightness. The possibility of lamp failures due to water drip or condensation is entirely eliminated by the patent external top connecting box. The lantern is wired internally with special heat-resisting conductors between the connecting box and the G.E.S. porcelain lampholder, the latter being adjustable to vary the direction of the main beams. The external finish of the lantern is aluminium colour.
