WEMBLEY LANTERNS
(MADE IN ENGLAND)
F 5451/7
|
F 5441/7
|
The series of "Wembley" lanterns has been evolved as the result of many years of experience and research work. They incorporate
a number of special features for ease of maintenance and maximum efficiency. The refractors are designed to give the maximum light
output and ideal candle power distribution.
Types F 5451/7 are totally enclosed and therefore dustproof. An occasional wiping of the outer globe is all
that is generally necessary to maintain maximum illumination. The interior will only need attention in this respect at the
end of long periods and this can be done when it is necessary for the lanterns to be opened for lamp renewal purposes.
Types F 5441/7 are supplied without the outer enclosing globe, and are therefore more inexpensive models.
The "Wembley" lanterns shown above are designed to accomodate three types of G.E.C. English-made refractors, each giving a
different light distribution. A plan of the typical light distribution is given below.
G 501
Symmetric. Peak at 70°.
|
G 507
Non-axial asymmetric. Peak at 75°.
|
G 513
Axial asymmetric. Peak at 75°.

lantern given by the new G.E.C. English-made refractors, giving approximate candle power
in peak directions at the angles from the lower vertical shown.
