Ediswan full range | Mercury Lanterns




London / London Major
Introduced in 1932 as the "London" Lantern and employs the Ediswan Prismatic Refractor with pressed glass outer globe and provision for exterior focussing.

These lanterns provide a non-axial light distribution. It is equipped with a prismatic refractor globe with internal prisms, the outer surface, with the exception of the path side, being quite smooth, thus reducing to a minimum the collection of dust and greatly facilitating cleaning. The head embodies a drip proof wiring chamber housing a porcelain connector. At the top is fitted an aligning flange tapped 1", which ensures the lantern will hang plumb. The internal reflector is finished white vitreous enamel.

Takes Incandescent or Mercury Discharge Lamps. For Group A roads.

This lantern embodies a simplified form of reflector system on the same principle as that used by the Northbury lantern and gives full light control in both vertical and horizontal planes. It also has a non-axial light distribution. The body and canopy are constructed of heavy guage copper and is fitted with a cast-iron cap, which forms a drip-proof wiring chamber and houses a shrouded terminal block. The optical system consists of a chromium-plated reflector which forms part of the canopy, and below, a pair of silvered glass reflectors mounted on the bottom hinged panel of a body, allows easy access to the interior for cleaning and lamp renewal. The body is glazed with diffusing glas panels.
