• Dual purpose lantern with unique optics provides both 'cut-off' and 'semi cut-off' distribution from a single lantern. A simple adjustment of the lampholder and lamp support bracket alters the position in the housing to provide the two light distributions with no additional components.
• Optical system designed to meet the BS1788 and BS4533 'cut-off' and 'semi cut-off' and C.I.E. 12 'semi cut-off' requirements.
• Versatility of the product reduces spares stock and maintenance costs. Greater visibile uniformity on lighting schemes.
• Basic modular construction. A complete lantern comprises of three separate components: canopy, prismatic bowl and spigot entry module.
• Canopy and bowl can be standardized throughout the scheme.
• Spigot entry module available without control gear housing or with integral hinged gear shoe. The modular construction offers easier installation, maintenance and lower maintenance stock.
• Injection moulded acrylic reflector bowl with high quality interior prisms.
• Hinged gear shoe when released from safety catches can be completely removed for replacement.
• Electrical connections are made by plug and socket and the integral gear version incorporates replaceable cartridge fuse link.
• The canopy is constructed in glass fibre re-inforced polyester (GRP) and formed by a special pressing method, giving a very smooth surface structure that discourages dust and grime from settling. The pressing method prevents inherent stresses from forming in the canopy during construction, and combines great mechanical and tensile strength when subject to vibration.
• The GRP canopy is self-coloured white throughout and combines an additive to improve UV resistance. It is light in weight, is resistant to chemical and weather influences and will not discolour.
• Lamp compartment is housed in the canopy module separate from the control gear module; a specification requirement now in force in many countries for motorway lighting.
• All internal wiring is of heat resistant material.
• Low profile canopy with low drag sepcailly designed to minimise the windage area and so reduce the amount of street on the column.

To specify state:

• Lanterns shall be certified by the British Standards Institution as fully complying with the requirements of BS 4533: Part 2: Section 2.7: 1976.
• Lanterns shall be of a type currently acceptable to the Department of the Environment.
• The Lantern shall ahve a downward light output ratio of 0.74 (cut-off) or 0.75 (semi cut-off).
• The Lantern shall be totally enclosed side entry mounting on 42/48 mm o.d. spigots 100 mm long and suitable for use with SOX low pressure sodium lamps.
• The Lantern shall have, as an integral part of the design, adjustment for both 'semi cut-off' light distribution and 'cut-off' light distribution.
• The Lantern shall have International Protection category IP23.
• The Lantern shall be similar to Philips MA SOX range.
