Industrial And Street Lighting Fittings And Accessories

Despite being relatively incomplete, this photocopied remnant of a GEC catalogue from 1923 documents the start of new thinking about street lighting with the introduction of the Longitudinal Lighting Lantern. It was designed by Haydn T. Harrison, who was probably acting as a contractor or consultant for the GEC, and includes optics to produce the first axial-asymmetric light distribution.

(His ideas of using reflectors, axial-asymmetric distributions, and parabolas would culminate with his Bi-Multi system several years later).

The rest of the catalogue details the many housing-type lanterns introduced in the 1920s, most sold as slightly reduced prices.

It is interesting that two pages are devoted to the new Directional System of Street Lighting; yet the City Lantern with the Holophane refractor has little more than a page and single-line description.
