G.E.C. "Birchfield" Street Lighting Lantern
Totally enclosed dust-proof lantern specially designed for OSIRA lamps. The body is onstructed of heavy gauge copper
with internal stiffening ribs, with a hinged bottom panel to give access for cleaning and re-lamping.
The upper canopy overhangs the main frame of the body. Two special prismatic glass plate refractors when used with
the spreader glasses produce an asymmetric light distribution. The optical system is specially designed by G.E.C.
Research Laboratories to produce high and even road brightness with absence of glare.
The lantern is supplied with an
inner porcelain enamelled reflector with a G.E.S. lampholder so that the lantern is suitable for 250 and 400-watt
OSIRA lamps, the lampholder being wired with heat-resisting conductors to a G.E.C. patent external top connecting box
specially designed to eliminate all danger of lamp failure due to water drip or condensation.
The external finish of the lantern is aluminium colour.
