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.

By 1939 the London range (including a London Major, Medium and Minor) are the general utility units of the bowl refractor type for all sizes of vertically burning mercury discharge lamps or gas-filled incandescent lamps.

northbury
Designed for use with the "Escura" mercury vapour discharge lamp and also with regular incandescent lamps. A reflector system gives full control of the light in both the vertical and horizontal planes, thus ensuring correct distribution for bends and gradients as well as for straight roads. The light emission normally wasted above the horizontal is redirected onto the road surface ensuring high peak candle power and by lowering the intensity between 80° and 90° glare is reduced and visibility consequenty improved.

stepney
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.

Refractor-Reflector Lantern for use with horizontally burning Mercury Discharge Lamps. For the lighting of Group A roads. Light control by means of a combination of prismatic refractors and reflectors, care being taken to reduce the candle power at angles approaching the horizontal inorder to minimise glare. Lamp and optical equipment are totally enclosed within the lantern. There are only three glass panels, the area exposed for the deposit of dirt is reduced to a minimum and maintenance is simple. The lantern is constructed from aluminium alloy and iron castings and is fitted with a combined aligning union and drip-proof junction box, making installation easy.

ssa/1
Totally enclosed plate refractor lantern of unique design for use with 85W or 140W sodium discharge lamps. It consists of a cast canopy of corrosion resisting aluminium alloy and a Perspex enclosing bowl with precision cut Perspex refractor plates sealed to the inside so that the outside is smooth. The enclosing bowl slides open to give easy access to the interior. Felt runnings ensure smooth action and as the bowl is firmly supported in all positions, maintenance staff have both hands free for cleaning and relamping. A single knurled screw secures the slide in its closed positon. Water repellent, insect proof felt gaskets make the lantern completely weatherproof and a water baffle in the socket prevents the ingress of moisture from the suspension arm.
