LANTERN BODY
The body consists of a truncated moulded "Diakon" cone held between a cast aluminium base incorporating
the spigot cap, and a die-cast light alloy upper rim.
Two vertical rods join the base to the upper rim. A casting which slides on these rods carries the lampholder.
This enables the lantern to be focused for the full range of lamp wattages shown.
The light aluminium cast top canopy is hinged to the upper rim and secured when closed by a quick release
stainless steel toggle catch. The prismatic glass dome refractor is secured to its supporting plate by
spring clips. The plate is held in position by two short vertical rods screwed into the top canopy.
The lantern body is fitted with a terminal block, cable cleat and earthing screw. Two heat-resisting leads
are wired to the terminal block for connecting to the lampholder. The lampholder is supplied separately.
OPTICAL SYSTEM
A dome refractor controls the light distribution; three forms are available:-
1. Symmetric all-round distribution with Z6502 (ref.letter 'S') dome refractor.
2. 160 degrees non-axial asymmetric, main light output up and down the street just away from the kerb,
with Z6508 (ref. letter 'N') dome refractor.
3. Axial asymmetric, main light output directly up and down the street, with Z6514 (ref. letter 'A')
dome refractor.
Note: It is necessary to quote the reference letter identifying the light distribution required when
ordering lanterns.
