G.E.C. "Lewisham" 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 an re-lamping.
The outer surfaces are finished aluminium. The lantern is supplied complete with porcelain enamel inner
reflector and two special prismatic glass plate refractors to suit the light distribution of the
OSIRA lamp. The lantern 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 (see page 22). 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.
