ELECTRIC LIGHTING
THE BRITISH THOMSON-HOUSTON CO. LTD., LONDON, W.C.2
Intensive research on street lighting problems and the accumulated knowledge derived from many years' experience in
outdoor lighting practice have enabled this company to develop Mazda Street-lighting Lanterns for every type of location

FLUORESCENT STREET LIGHTING LANTERN.
This lantern has now been operating for more than three years in many of the world's most
famous highways. It houses three 5 ft. 80-watt fluorescent lamps. It can be mounted directly on street standards, or over the
centre of the roadway on catenary wires. The complete absence of glare creates safer road conditions for both driver and
pedestrian.

STYLIZED RANGE OF SIDE-ENTRY LANTERNS
A new series of Mazda Side-entry Lanterns has been designed to meet hte demand for a
complete range of lanterns accommodating every type and size of vertically-operated tungsten and mercury vapour street lighting
lamp. This new "Stylized" range consists of sixteen lanterns and, for the first time, lanterns of uniform appearance can be installed
throughout an entire city and on all the roads leading to it. The varied requirements of such locations as shopping centres,
side streets and car parks are all catered for in difference of size, glassware and type of lamp.

HORIZONTAL ENCLOSED LANTERN
The main features of this new lantern are a first-class optical performance combined with very
simple erection and maintenance. Magnetic arc control enables the standard type of vertical-burning mercury vapour lamp to be
used in a horizontal position. The well-known BTH principle of controlled cut-off is employed to give constant visual accommodation
and a minimum of glare. This, allied to the horizontal light source, gives the maximum continuity of road brightness and optimum seeing
conditions.
