Abstract
The economics of gas street lighting, particularly those for “Group B.” have been greatly improved since the war by changes in the design and construction of the lanterns.
Considerable experience has now been gained of the performance in service of the new units. Their performance is consistent with the requirements of the new Draft Code of Practice for Street Lighting.
This paper describes the changes in design of lanterns and control gear which have been made, and reports the results of full-scale tests carried out on certain installations. Attention has been directed to improving both the performance and the daytime appearance of the lanterns.
Illustrations of post-war installations are given.
