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.
