Winsdor Lantern
Probably the most popular of the square, glazed pane type of lamp. In 1945, described as a soundly constructed square lamp with mirror glass faceted reflectors. Its high efficiency, storm-proofing and ease of maintenance were its main features. Quite suitable for Group "B" lighting schemes.

Rochester Lantern
The firm claimed to be the originators of this type of lantern. Available in "upright" or "suspension" options. Could take 4-8 mantles, with either single or dual supplies, and with clustered or "in-line" arranagements. Could also be supplied with either: "Multi-ray" reflector; "K" or "S" type Directional Reflector; Holophane Dish and or Band refractors. Clock controller, governor and/or controller could be fitted in the base. Was the lantern of choice for the City of Westminster and was installed on the Great West Road in 1936. In 1945, it has a variety of applications in either Upright or Suspension form and can be applied in most street lighting scheme. It meets the requirements of the Ministry Of Transport's Final Report.

London C Pattern Lamp
The London lamp was desgined to break away from the conventional shape of gas lamps and to incorporate within the lines of the unit all the necessary reflector equipment. The great advances made in the manufacture of heat resisting backing for mirrors enables mirror glass reflectors to be employed with consequent high reflection efficiency. Ventilation on the Venturi flue principle not only reduces the overall height of the lamp, but in conjunction with the patent improved air-gas mixing arrangements increases the lumen output of the light source. The "C" pattern lamp incorporates within the design of the unit accommodation for the clock controller, pressure governor and igniter. The reflector system is similar to the "B/2" pattern.

London B Pattern Lamp
The London B/2 was described as new in 1937, although it was being installed in 1936 and described as "widely used." It replaced the picture of the "C" pattern lamp in "The London Lamp" advertisement in September 1936. (The B/2 probably designates the use of number 2 mantles). It was of simplier construction and more universal application. A reflector system similar to the "C" pattern lamp is incorporated. The design of the reflector equipment is such that the candle-power at angles very near to, or above, the horizontal, is low; by this means glare in the normal line of vision is reduced to a minimum and the flux utilisation of the source is high. The only adjustment provided on the reflectors raises or lowers the angle of maximum intensity to suit various spacing height ratios, and to obtain a compromise between reasonable test point illumination and road surface brightness.
It was described as "self-focussing" and was fitted with a unique reflector system which gave excellent visibility and reduced glare. The use of shaped glass reflectors gave a very high degree of light control without undue absorption. A low-pressure unit with a streamline flow superheater carrying six, eight or twelve No. 2 mantles in alignment. Special mirror trough reflectors with heat resisting backing are used to give a wide distribution up and down the road. The "Venturi" type flue reduces the height of the lantern, and ensures steady burning udner the most adverse weather conditions. The burner incorporates a novel air control resulting in a very efficient light output.
For use in "busy" streets. It was exhibited at the APLE's 1937 conference at a spacing of 135' staggered, 25' height and giving a Class "D" classification. The lamps were adjusted to give a good compromise between surface brightness and horizontal illumination. In 1937, the lantern is available in four sizes. The mantles are arranged in line, the directional equipment consisting of special heat resisting mirror glass troughs of parabolic section. The reflector system is held in a rigid frame which also carries a compensating plane refelctor. The function of this compensating reflector is to redirect the light that would otherwise be wasted above the horizontal on the road surface adjacent to the lamp. Its output was increased in 1938 by a new burner design which gives an exact air adjustment and the optimal gas-air mixture for gases of different composition. By 1945, the lantern had been extensively used, now being built in accordance with the MOT's Final Report for Group "A" lighting. Has a special mirror glass optical system which can easily and accurately adjusted to suit any change of gradient in the road. Alternative Special Reflector Systems could be supplied to give either a low cut-off system or a back refelctor for unilateral distribution.

Adjustment of reflector system in situ: The rigid frames are pivoted and the angle of maximum intensity can be adjusted locally by means of two lead screws shown at B, B, which pivot the frames independently. The reflector system is thus adjustable to secure the optimum result for the particular system.

High Visibility / H. V. Lamp
First exhibited and installed in prototype form at the APLE's 1937 Conference in Folkestone. Originally called the "H. V. Lamp" which could stand for "High Visibility." The exterior of the final model was to be considerably modified, but the redirective equipment was to be retained unaltered. The lamp used specially designed mirror glass reflectors (Zeiss Directional Reflector) giving a complete cut-off below the horizontal, together with an axial beam intensity at angles of 60°-70°. The type of distribution ensured that a much greater proportion of the total flux reached the road surface, resulting in higher illumination for a given gas consumption. And the design of the lamp such that its weight for a given light output had been considerably reduced making it possible to suspend two or three lamps on a single span wire. It was the prototype of the "Folkestone" lantern - see below.

Folkestone Lantern
First exhbitied in embryo form at the APLE's 1937 conference in Folkestone as the HV Lamp. Even though conference literature suggested the lamp would be externally redesigned - but retaining the optical system - the lamp appeared for sale, now called the "Folkestone" lamp, the same month. The design was perfected in 1938. It was of the "cut-off" type and installations were characterised by an entire absence of glare and amazing visibility.

Series 8000
The whole of the body of the lamp is cast aluminium. It is arranged as a unit with a Wrought Iron Swanneck and Controller Base, the control equipment being housed in a lifting sheet-iron cover. THe Lamp is fitted with curved mirror glass reflectors. A three-way version for Group "B" lighting at junctions was introduced in 1938. Two of the swan neck options are the "B" type and "D" type. Tests have proved that the efficiency of the "8000" Lamp referred to the total lantern lumen output per c. ft. of gas consumed, is considerably greater than that of any other low pressure gas unit of normal design at present available. This high burner efficiency is obtained with silk mantles or normal impregnation.

Highway Lantern
Designed in 1939 and exhibited at the APLE's conference the same year. The reflector system embodies paraboloid reflectors giving a distribution of light adequately wide for all normal roads, with a polar distribution particularly suited to the production of high road brightness but at the same time controlled to prevent excessive glare. The reflector system has a low absoprtion giving high total lantern lumen output. The burners carry twelve mantles in a special arrangement of two rows, and project considerably below the flat top reflector. The anodised aluminium specular reflector system consists of two complete reflector units and mountings, each adjustable over a wide range horizontally and also vertically if necessary. These units are easily removed, and the burner can then be detached for maintenance. Designed for Group A lighting at 25', 5' overhang up to road widths of 40'. A novel point on the lamp is that it has been found possible for the first time to calibrate the reflector mounting in degrees laterally, thereby greatly simplifying their adjustment. The lamp body has four doors, self-supporting when open, for easy of maintenance. The whole top of the lantern is made from copper, and the basket is also incorrodible.
