| Light distribution in a vertical plane through maximum intensity.
The polar curve is based on an average light output through life from two
60W Osram pearl G.L.S. lamps (1,150 lumens average).
Light distribution data are given for the guidance of the lighting engineer
and represent the average results of laboratory tests on a number of lanterns
taken at random from stock. The data are based on the lamp characteristics
state: if the latest lamp efficiency is different, the candela or lumen values
should be calculated in direction proportion to the relative lamp lumens.
Lantern Weights:
Z5720: 7½lb (3.39kg)
Z5725: complete with gear: 11lb (4.99kg) |
