This street-lighting lantern consists of a canopy made of copper spinning reinforced with wrought-iron
spider, and a globe cage in basket form consisting of wrought-iron strips attached to a cast ring. The globe is
of BTH "Nelite" glass. An all-porcelain lampholder and inner reflector in white vitreous enamel are employed.
The BTH "Nelite" glass globe is of the rippled variety with a trace of opal, giving excellent diffusion,
but not materially interfering with the directional control. When lighted at night, the rippling gives the
effect of innumerable minute crystals which give life and sparkle to the lantern, which is not found with
plain opal globes. At the same time there is an absence of glare. The rippling also has the advantage
of making the globe practically self-cleaning, since rain falling on it is drained off naturally by the
small channels, and carries away a good proportion of any dirt that may have collected.
