The lantern body consists of two die-cast light alloy end pieces built on to a 9
in. aluminium alloy extrusion. Two sleeves are incorporated in the body to receive the bracket mounting
arm. All auxiliaries together with the wiring harness and lampholders are within the body on a detachable
die-cast aluminium gear tray. The gear is enclosed by a hinged aluminium over-reflector secured by
quick release turn buttons. The 'Perpsex' bowl is hinged to the lantern body and secured by
stainless steel spring catches. NOTE: A tapered 'Perspex' bowl can be supplied to special order. |
Two 'Perspex' refractor plates are cemented one to each inner
side of a 'Perspex' bowl. |

The lantern body is essentially a 'Perspex' cylinder, through which runs a steel barrel screwed at
its lower end into a cast iron spigot cap. The lower copper spinning encloses the tube operating gear which is supplied
with the lantern. The 'Perspex' cylinder fits over this assembly. The top copper spinning is secured by a spun copper
finial. |
The opal 'Perspex' cylinder provides a diffusive symmetric light distribution. |
