Is of the open reflector form. Can be supplied in various types providing an asymmetric distribution of light in two, three or four directions at angles to suit varying road widths, junctions, intersections and mounting arrangements. Silvered mirrored glass reflectors normally used but white opal glass can be substituted if desired. (Opal glass has an extremely long life when employed in corrosive or humid atmospheres but the intensity of the peak candle power is not so high as for mirror reflectors). The silvered mirror reflectors are of a single piece of glass bent ot the correct contour and cemented into the cast iron backings. Diffusing glass is used to prevent glare as the whole of the surface appears equally illuminated. The distribution is wider than htat provided by other similar types of unit and the intensity of the peak candle power is higher, due to the greater control of light effected by the larger surface area of the reflectors. The cast iron backings are easily detachable from the top and body of the fitting for: (1) Nesting for packing and stocking; (2) Facilitating wiring and erection; (3) For replacements and (4) Interchangeability. For use with clear OSRAM lamps. Standard taping ¾" gas. Focussing screw accessible and rapid. Stout durable copper body (top cylinder). Standard finish is green.

The series of "Wembley" lanterns has been evolved as the result of many years of experience and research work. They incorporate a number of special features for ease of maintenance and maximum efficiency. The refractors are designed to give the maximum light output and ideal candle power distribution. This family are totally enclosed and therefore dustproof. An occasional wiping of the outer globe is all that is generally necessary to maintain maximum illumination. The interior will only need attention in this respect at the end of long periods and this can be done when it is necessary for the lanterns to be opened for lamp renewal purposes.

Made from heavy gauge sheet copper. Enamelled green outside and white inside for reflecting surfaces. With copper top and ventilator. The ventilator is a patented device operating on the ejector principle is fitted combining extreme simplicity with highefficiency. This device causes a steady stream of air to be drawn into the lantern and ejected from beneath thetop cowl. Exhaustive tests have been carried out with this ventilating device, special attention being given tolamp performance. The result of these tests demonstrates convincingly that the ventilation is such as to safeguard the lamp from overheating and consequent reduction in normal life. The focusing device is a special patented feature which enables the lamp to be raised or lowered inside the prismatic refractor,thus varying the distribution of light to suit the height and spacing of units. All such adjustments in the largersize "WEMBLEY" lanterns are made from the outside without opening the lantern in any way. The lamp is lowered until the filament is sighted across the bottom edge of the refractor; the knob is turned a predetermined number of times to the right, and adjustments can be made to the 1/100th part of an inch. The lantern is made in various sizes to accommodate OSRAM gasfilled lamps of either 100 or 1500 watts, suitable for main thoroughfares, suburban streets and residential areas. The light emission is ideal for street lighting, the maximum candle-power being given at the useful angle of 70° from the vertical. The 300-500W GLS model (FC.6047) could be converted for use with OSIRA lamps by means of general conversion units - likewise the 1000-1500W GLS model could also be converted with similar kits.

One of the "Clearspace" range. This lantern is solely designed for outdoor sub-station lighting. It has been approved by the C.E.G.B. for use in their sub-stations. It is intended for mounting at a height of 8-10 ft. above ground. A special 8 ft. pivoted steel column has been designed for use with the lantern so that it can be maintained by a man standing on the ground. The lantern is designed to project a concentration of light at angles of 10° to 20° above the horizontal where it is most needed, and to restrict intensities at and below the horizontal.

Control of the light distribution is obtained by the use of a prismatic glass refractor. Three types of refractor are available: symmetric distribution (S) (Z 6504); non-axial distribution (N) (Z 6510) and axial asymmetric (A) (Z 6516). The choice of refractor depends upon the relative positions, as seen in plan, of the lantern and the apparatus requiring most illumination.

The entry at the bottom of the lantern is tapped 1½in. B.S.P.; a grub screw is fitted for locking the lantern on to the support.

The lantern body is of non-ferrous cast alloy, specially selected for its resistance to corrosion. It has a cast alloy hinged ring holding the glass globe which can be swung open to give access to the interior. These alloy castings are Pyluminised and finished stove enamelled aluminium colour. The lantern is totally enclosed and dust proof, a neoprene gasket being provided on the lip of the glass globe. The hinge pin, screw fastener and screws exposed to the weather are of stainless steel.

An aluminium heat baffle is provided above the lamp to prevent excessive heating of the special glass globe. The refractor is supported on a white vitreous enamelled plate and held in position with spring clips.

A double-headed arrow on the outside of the lantern indicates the direction of the main beams of light, and both the refractor and refractor plate can be fixed in only one direction.

G.E.C. directional street lighting reflectors, open pattern, can be supplied in various types for providing an asymmetric distribution of light in two, three or four directions at angles between the reflectors to suit varying road widths, junctions, intersections and mounting. These are fitted with single piece silvered glass mirrors bent to the correct contour, and cemented into cast iron backings which assist in ensuring long life to the silvered surfaces. Diffusing glass used to prevent objectional glare, as with it the whole of the surface appears equally illuminated. The cast iron backing holding the silvered glass reflectors are easily detachable from the top and body of the fitting by unscrewing two nuts. This facilitates nesting for packing and stocking; wiring and erection; replacement in the event of breakage; and has the additional great advantage of interchange ability, as tops and bodies are universal for all patterns. Robust cast iron top. External focusing screw, heavy gauge copper body. Single piece English-made diffusing mirror glasses secured by special cement in protecting iron casting. Standard tapping, ¾-in. gas. Standard finish - Green

For side road lighting, mounting height 13 ft. - 15 ft. and spacing 100 ft. - 120 ft. Greater spacing will produce dark areas midway between lanterns. For road widths up to 30 ft. Two forms of lantern body can be supplied. One is top entry ¾ in. gas, the other is sloping side entry 1 in. gas barrel unthreaded. In the latter case a ¼ in. Allen grub screw locks the lantern to the bracket. Each body is made of die-cast light alloy and consists of two detachable wings, a main body casting and a top, which, in the case of the sloping side entry form, is a light alloy spinning. An earthing screw is provided. Each wing carries six identical facet mirrors, therse are silvered and lead backed and held in position by lead clips. In the event of damage, replacement is simple. The light distribution is very good and the glare ratio conforms to the recommendations of the M.O.T. Final Report 1937, though it is necessary, when used with H.P.M.V. Lamps, to replace the four lower mirror facets with pot opal facets. If this is not done, the directional intensity ratio is about 5.5. The lampholder is carried on a bridge piece which slides on two vertical rods. One rod is marked with the correct focal positions for the various wattages of lamp. The light alloy is spcially selected for its resistance to corrosion. Further protection is obtained by the use of a suitable primer, undercoat and matt aluminium top coat.

Totally enclosed dust-proof lantern, specially designed for low wattage OSRAM gasfilled lamps constructed of heavy gauge spun copper body with cast iron top, omplete with porcelain enamelled steel inner and outer reflectors. The outer reflector is hinged and provided with a locating notch for a G.E.C. prismatic glass bowl refractor, which, with a felt gasket, makes the lantern dustproof. An inner symmetric refractor converts the light from the OSRAM lamp to the vertical shaped source for correct light distribution by the outer bowl refractor. An external focusing knob is provided so that the correct positions of the different wattage lamps can be immediately obtained. The lantern is supplied with a felt gasket. The patent G.E.C. top connecting box, designed to eliminate lamp failure due to water drip or condensation, is wired with heat-resisting leads to an E.S. porcelain lampholder.

The external finish of the lantern is aluminium colour with all reflecting surfaces heavy vitreous enamlled. An important feature of this lantern is that by the removal of the inner symmetric refractor and the replacement of the inner reflector by one of a different shape the lantern becomes suitable for use with the 80 and 125-watt discharge lamps.

Introduced in 1936. First installation along Banbury Road, Oxford. For main road lighting. Designed to use the GLS lamp with the MA/V Glass Bowl Refractor - therefore an inner symmetric dome refractor is used to produce the vertically shaped light source for control by the outer bowl refractor.

Totally enclosed dust-proof lantern for use with 300/500-watt OSRAM gasfilled lamps, body constructed of heavy gauge spun copper with porcelain enamelled steel inner and outer reflectors. The outer reflector is hinged and provided with a locating notch for a G.E.C. single piece prismatic glass bowl refractor. This refractor was specially developed and designed by the G.E.C. research laboratories, and is identical with that used on the Di-fractor lanterns. It produces a very high standard of road brightness and at teh same time the whole surface of the bowl appears evenly illuminated, so avoiding the glare which is produced by less carefully designed imitations on which only a small section is flashed. An inner symmetric refractor prodcues the necessary vertical shaped light souce for control by the outer glass bowl refractor. An external focusing knob is provided so that the correct positions for the different sized lamps can be immediately obtained. The lantern is supplied with a felt gask and a wire net. The patent G.E.C. top connecting box designed to eliminate all danger of lamp failure due to water drop and condensation is wired with heat-resisting leads to the G.E.S. porcelain holder.

The external finish of the lantern is aluminium colour with all reflecting surfaces heavily vitreous enamelled.

An important feature of this lantern is that by removal of the inner symmetric refractor and the replacement of the inner reflector by one of different shape, the lantern becomes suitable for use with OSRIA lamps.
