Prototype shown at the APLE Conference in 1945. Introduced in 1945 for post-war Group "B" lighting schemes. Equipped with
2,3 or 4 burner superheaters for either BS.1 ("Bijou") or BS.2 ("Medium") mantles. The burner was specially
designed for the lamp: it has a high burner output per cubic foot of gas, and
stability under wide variations of gas combustion characteristics. Lantern is made
of 20 s.w.g. copper, rivitted together, and mounted to either a swan-neck bracket or wall
fixing bracket. A polished stainless steel roof reflector can be supplied as an alternative
to the vitreous enamelled reflector. A combined constant pressure governor and remote control ignition
valve has been fitted to ensure: (1) Uniform lighting at all time; (2) Economy in the use of gas;
(3) Prevention of back-firing due to accumulation of air in the swan neck. The unit is designed for use
with Newbridge 3A/UNI controllers. Horstmann Comet igniters may be fitted to order in a neat, weatherproof
housing.
In 1946, tools have been provided for quick and accurate production of the many parts in the
lamp. Many improvements have been embodied in the design: (1) The Clock Controller can be removed
from the controller box by unscrewing two set screws; (2) Horstmann Comet Ignitors can now be
employed; (3) The combined Constant Pressure Governor and remove control valve are housed in a neat pressed
copper box. Access to these devices is easily obtained by unscrewing a knurled nut to remove the cover; (4)
The glazing of the lamp can be completed within two minutes using special clips; (5) A new
design of burner has been incorporated in which all primary air is drawn from outside the lantern to ensure
stable flame conditions. It is a modern, efficient and attractive unit for Group "B" lighting.
In construction it is a first-class engineering product, its special features including the use of heavy gauge
pressings, all rivetted construction and superheaters specially proofed against corrosion, both internally
and externally.
It is a compact lantern with a special arrangement of the control equipment which
is housed in the cast box forming the socket which fits on to the top of the column.
