An ornamental unit with asymmetrical distribution curve suitable where "White Way" type of lighting is preferred to lighting having a directional characteristic. It has a cast aluminium canopy carrying a 24" reflector and an ornamental diffusing globe. The globe is carried on an aluminium spinning which is much safer than the customary three set screws. The base of the globe is finished off with an ornamental copper spinning. The globe can be lowered for cleaning purposes and for lamp replacement and when lowered is suspended by chains so the operator has both hands free for cleaning.

Lantern designed in 1936 for the newly-introduced MAT/V lamp. First installed in Preston. Could provide a symmetrical light distribution. For use with the Siemens Sieray-Dual lamp. The metal work of this lantern is exactly the same as the Charlton-Sieray but is fitted with a larger globe of white glass.

Described as newly introduced in 1936. Exibited at the Public Works Congress in 1937. Designed for use with the Siemens Sieray "H" lamp. Probably named "Regent" after first installation in Regent Street, London, although there's no literature to back that up. Designed fro asymmetric distribution with 160° or 180° spread between the main beams, light control being effected by Holophane refractor panels. It consists of a cast-iron hinged top enclosing the wiring chamber, cast aluminium alloy canopy and bottom framework, with the side angle pieces of heavy guage brass. A special feature is the complete isolation of the lantern interior from the wiring chamber, connection between the two by means of Mica insulated terminals so sealed-in as to be watertight. Condensed moisture cannot possibly enter the lantern from the bracket arm whilst the lead wires are totally enclosed.

First described in 1937. A blended-light lantern which could take one mercury discharge lamp and two gas-filled tungsten lamps. Provides a directional distribution. Could've been named after the first installation in Gower Street, London; but the literature is sketchy and only MV Gower lanterns have been explicitly mentioned as being used.

Believed to be the Holophane Bi-Way. Exhibited at the Public Works Congress in 1937. For Group A lighting. Could take the Siemens Sieray "H" lamp. Can be supplied with two-way axial asymmetric, two-way non-axial asymmetric or symmetric light distribution. The Holophane Bowl Refractor is manufactured in one piece with an outer surface that is smooth except on the pavement side. It has a reflecting segment on the pavement side for redirection towards the street, and a series of prisms adjacent to the flange, for refraction of the upward rays emitted by the lamp. The body of the lantern is soundly constructed and very robust. Hinged cast rings carry the glass refractor and are connected together by 3/8in. diameter steel rods. The outer casing is of heavy gauge spun copper, and the reflector of vitreous enamelled steel. The refractor is secured to its ring at three points and cannot be dislodged accidently when the lantern is opened. Lamp focussing is by means of an adjustable cast bridge. The cast head incorporates cable inlets anda separate wiring chamber heat insulted from the body of the lantern, the design being such as to prevent the ingress of water into the lantern. A new design of this lantern was made available in 1945 which utilised a Holophane bowl refractor. It used a Holophane one piece bowl refractor which can be supplied to give two-way axial, two-way non-axial or symmetrical light distribution

Believed to be the Standard Type Holophane Duo-Dome. Exhibited at the Public Works Congress in 1937. The lantern consists of a cast iron body with detachable hood and vitreous enamelled reflector. It is fitted with an external focussing device attached to the hood. The Holophane Duo-Dome Refractor is smooth on both the exterior and interior surfaces and is attached to the reflector by means of an internal copper sleeve. It can be supplied with two-way axial, 150° or symmetrical distribution.

For Group A lighting. A more decorative version of the Regent-Sieray. Designed for use with the Sieray "H" type lamp (MA/H) but also could accomodate the Sieray-Dual lamp (MAT). Gives an asymmetric light distribution with a spread of 160° between main beams, the control being effected by Holophane refractor plates. Made of non-ferrous metals expect for the cast iron top and vitreous enamelled reflector. By 1945, refractor plates for either 160° or 180° main beams were available. Similar in construction to the Regent-Sieray Lantern except it's fitted with a dished bottom door, glazed with diffusing glass, which improves the appearance of the lantern without detracting from its efficient light distribution. The extra depth allows accomodation for the 500W Sieray-Dual Lamp.

arp lantern
Complies with British Standard Specification BS/ARP 37. For wartime use. The large area of the reflecting surface is utilised therefore night appearance is good. The large diameter (12") provides good daylight appearance. For mounting heights of 19' and upwards, at a spacing in plan of not less than 100', when fitted with 25W pearl lamp. When so installed a general level of illumination of 0.0002 foot-candle will be provided and howhere will the value exceed 0.004 foot-candle. The fitting consists of a standard 12" diameter R.L.M. Reflector, stove-enamelled black inside and outside, carrying an annular slotted mask so designed and located as to procude the desired light distribution. The exterior of the mask and the interior of the bottom portion are stove-enamelled black; the cylindrical upper portion is stove-enamelled white inside. Access for cleaning and relamping is provided by the removal of the bottom portion of the mask. In designing this reflector the Siemens lighting engineers have aimed at producing a fitting giving its resutls through the medium of large areas at low lighting intensities e.g. the reflector is flashed to a depth of approximately 2¼" whilst a reasonably broad ring of light is emitted from the slot in the mask. In this fitting the mask is fixed to the top of the reflector.

concrete lantern
For Group B lighting, this design evolved in collaboration with Concrete Utilities in 1945 to form part of a concrete bracket arm. "The cast concrete head carries a ring, to which are fixed the lampholder supports, porviding three lampholder positions, and to which a Holophane Duo-Dome refractor is attached by three special fasteners. A quarter-turn of these fasteners instantly frees the refractor for cleaning etc., without the removal of any stud or nut. All rings and supports, etc., are made of non-corrodible metal, consequently maintenance is reduced to the absolute minimum. A Concrete Lantern for Group 'A' lighting is in course of development, and this will incorporate an ingenious method of dissipating heat from the lantern interior, the subject matter of a patent."

newton-sieray minor
For Group B lighting. A side entry lantern fitted with a single-piece Holophane Dome Refractor. It is made with a one-piece cast canopy and reflector and is tapped ¾-in. gas thread as standard (with provision for 1-in. if required). In the top of the lantern are three pairs of cast lugs, to one of which a strap is fixed which carried the appropiate lampholder. These are arranged that any lamp for which the fitting is designed will take up its correct focal position. The strap carries a porcelain skirted pattern and is of the B.C., E.S., or 3-pin B.C. type. The reflector is stove enamelled white on the reflecting surface. The glassware is available with two types of distribution: symmetric and 2-way non-axial with 170° between the main beams. The maximum candle power is at 78° to the downward vertical. The glassware is held in position by two phosphor bronze rods which are secured to the main casting, the necessary locking being obtained by two phosphor bronze springs. Provision is made for locating the glassware correctly in respect to the body of the lamp. Could also be fitted with an optional clear glass outer globe.
