kington lantern

The Kington is a refractor lantern for three 5 ft. 80W fluorescent lamps (Type MCFA/U). It provides good light distribution on the road. It is economical in use with reliable components which keep maintenance costs to the minimum. It has a good daylight appearance.

The lantern is supplied with wired complete with AEI Instance Start Control Gear.




Application
For Group A roads. The Kington lantern is particularly suitable for lighting city centres, boulevards, promenades, car parks and similar places of assembly. Light distribution is recommended in the British Standard Codes of Practise C.P. 1004 : Part 1: 1952.




Specification
The canopy is made from magensium aluminium alloy sheet which is cemented and screwed to silicon aluminium alloy end castings. The lamps are protected by a 'Perspex' bowl which hinges sideways on 'Diakon' higne blocks cemented to the bowl. Quick release catches scure the bowl, and maintain an even pressure on the sponge rubber gasket, thus making a weather-proof seal. All external parts are of non-corrosive material. A slight tapering of the bowl, with the absence of welded joints in the canopy contribute to the clean, functional appearance of the lantern.

The Instant Start Control gear is mounted on a tray which is concealed by a hinged sheet metal cover. Two brackets each carry three lampclips mounted vertically above each other are bolted to the cover at either end.

Push on Bi-pin lampholders are fitted.




Light Control
Optical Control is by means of sealed-in 'Perspex' refractor plates on the inside of the bowl.




Mounting
Side entry cantilever for 1½" plain B.S.P. bracket, 19¼" max. length. The lantern is designed for a mounting at an angle of 10o above the horizontal.

Light Distribtion data are only given for the guidance of the Lighting Engineer and represent the results of laboratory tests on a typical lantern taken from stock. The data are based on the lamp characteristics stated; if the latest lamp efficiency is different, the candela or lumen values should be calculated in direct propotion to the relative lamp lumens.
