Abstract
THE General Electric Co., Ltd., has developed a road obstruction lantern which complies strictly with the Lighting (Restrictions) Order, 1940. The use of these electric lanterns for fixing to street bollards or other supports has many advantages. Not only does it mean a saving ranging from Id. to 6d. per lamp per day, but it also saves in oil and man-power. According to Roads and Road Construction of June 1, in one London borough alone the saving effected in this way amounts to nearly £5,000 a year. The G.E.C. lantern is constructed of lead-coated sheet steel and has three sides, stencilled with the approved St. Andrew's Cross sign and backed with white opal glass. Inside are a detachable baffle and a B.C. lamp-holder for use with a 15-watt pearl Osram lamp. This provides the correct amount of light (0-5 candle per square foot) on the crosses. The lamp is easily accessible for wiring and maintenance. The lantern is supplied finished with either black or white outside. A two-lamp unit is preferred by some authorities because of the advantages of ensuring that there is a light on the island even if one lamp fails. The cost of the G.E.C. two-lamp lantern is little greater than that of the standard unit.
