The shape and general appearance of the lantern conforms with present-day practice. It is made in four sizes, having respecitvely six, eight, ten or twelve mantles, and the distribution has a wide horizontal spread. The lantern was developed from the well-known Avil "Strip" lantern. An intensive beam candle power is deliberately avoided by using flat glass reflectors which are specially treated by a process ensuring full resistance to conditions met with in use. These mirrors are situated above and below the line of mantles, there being no obstruction of any kind in front of the light source. Positioning of the mirrors is obtained by their being fitted into cast frames of light alloy which lift right out of the lamp for maintenance purposes. The setting of the mirrors according to the spacing of the units and other conditions under which the lamp is to be fitted is usually determined during manufacture. For side lighting the lamp is usually supplied with "Staybrite" steel reflectors attached to the inside of the mirror end frames to increase the beam spread across the road. The body, canopy and ventilator of the lantern are constructed from copper, and both end frames of the lantern are of cast brass. The end frames, together with a bridge piece, give the lamp complete rigidity, and the all-copper casing ensures a long useful life.

Designed for Group "B" roads (but could be used for Group A).

Described as the unit for kerb line lighting, which gives light to the road as well. A complete unit with controller base and bracket. It distributes two beams of light at 180° from each other along the kerb edge without producing glare. At the same time that portion of the light which would normally be thrown on to the houses at the back of the footwalk is distrubuted onto the roadway by means of reflector devices. It is usually supplied with a clock controller and a constant pressure governor housed in the base of the supporting arm of the lamp. Lamp is fitted with a bypass of the usual type and a level cock may be fitted. Casting is of light rustless metal and the superheated cluster of mantles is surrounded by a pear-shaped super heat resisting glass globe. Consists of two reflectors at right angles to the kerb and projecting almost horizontally from the body cating above the globe support, light from the lower hemisphere being collected and redirected by means of a glass refractor carried underneath the mantles and inside the globe. Light from the house side is dealt with by a special small reflector attached to the arm. All reflectors are capable of adjustment to suit bends in the road or hills.

The 1944 is fixed on an "A" Type bracket with ladder bars, having the No. 170 mirror reflector above the mantles, and Holophane Dish Refractor, No. 22/4400, in the globe, fitted with Newbridge 3A/UNI controller and Mark VII "Comet" igniter. The lamp has a globe of the normal type, size and fitting. The Type A Bracket provides accommodation in the base for controller, "Comet" igniter and governor and is normally 48" long.

The 1974 on "E" Type Bracket is suitable for new installations, and has a No. 170 mirror reflector and No. 175 back reflector in Firth's "Staybrite" Steel with Newbridge controller 15/3A/COM incorporating "Comet" ignition. Can be supplied with or without ladder bars and for bracket fixing to poles or walls.

Three other types of upright brackets are available for use with the "Sideway" lamp..
