Specification Clearside 5350/1/2 and 5354/5/6
Side road lighting; 15 ft. mounting height; spacing 100-120 ft. for best results;
road width up to 30 ft. The lanterns can also be used for space and area lighting.
Z5350 and Z5354: 60-200W Osram tungsten filament lamp, B.C. cap.
Z5351 and Z5355: 80W or 125W Osram MB/U or MBF/U mercury lamps, 3-pin B.C. cap.
Z5352 and Z5356: 60-200W Osram tungsten filament lamp, E.S. cap.
Top entry, the lantern is tapped 3/4 in. B.S.P. and locked to the bracket by a
1/4 in. dia. Allen-type grub screw.
Die-cast aluminium alloy. The Z5354 range have a white enamelled reflector plate which
carries the single piece prismatic glass dome refractor. The refractor is held by
two stainless steel spring clips. The Z5350 range have a plain white enamelled reflector
plate and no provision for a dome refractor. An earthing screw is provided.
The lampholder can be either B.C. or E.S. for use with Osram tungsten filament lamps or
three-pin B.C. for use with Osram MB/U or MBF/U mercury lamps.
The lampholder is mounted on a cranked bridge-piece carried on stepped lugs within the
lantern body; these provide adjustment for the various wattages and types of lamp
which can be used.
The Z5350/1/2 lanterns have a white enamelled plain reflector plate, held in position
by three screws.
The Z5354/5/6 lanterns have provision for a prismatic glass dome refractor giving three
alternative types of light distribution:
Note: The reference letter for the type of distribution required should be quoted after
the catalogue number when ordering.
- Z6502 (reference letter 'S') symmetric all-round distribution.
- Z6508 (reference letter 'N') 160 deg. non-axial asymmetric distribution.
- Z6514 (reference letter 'A') axial asymmetric distribution.
The alloy used is specially selected for its resistance to corrosion and is specially finished
to give a pleasing appearance.

1. (right curve) Light distribution in a vertical plane through maximum intensity.
2. (left curve) Light distribution around the lantern at 81° to the vertical.
Direction intensity ratio: 3:2 (for 200W lamp)
Light above horizontal: 5% (for 200W lamp)
Light output ratio: 89% (for 200W lamp)
The Polar Curves of the Z9354N lantern are based on an average lamp light output through
life from a 200W coiled coil Osram lamp (2725 lumens average).
Light distribution data are given for the guidance of the lighting engineer and represent the
average results of laboratory tests on a number of lanterns taken at random from stock.
The data are based on the lamp characteristics stated; if the latest lamp efficiency is different,
the candela or lumen values should be calculated in direct proportion to the relative lamp
Z5350/1/2: 2lb (0.91 kg)
Z5354/5/6: 3lb (1.4 kg)
