STREET LIGHTING EQUIPMENT
FOR "OSRAM" LAMPS IN REFRACTOR LANTERNS
G.E.C. street lighting lanterns are designed to accommodate four types of G.E.C. British-made refractors, each giving a different light distribution.
A plan of typical candle-power distribution of each refractor compared with a bare lamp is given below.
Full line indicates distribution from bare lamp.
Dotted line indicates distribution from lamp and refractor.
