§ 48. Mr. Russellasked the Minister of Transport and Civil Aviation the approximate cost per mile of installing and maintaining sodium-lighting on roads; and how the cost of this form of lighting compares with that of other kinds.
§ Mr. Lennox-BoydSodium-lighting usually costs between £3,000 and £4,000 per mile to install and averages about £650 a year per mile for maintenance, being generally a little cheaper to maintain than the other forms of lighting. Mercury lamps cost about the same to install. Tungsten lamps a little less and fluorescent lamps about 50 per cent. more.
§ Mr. RussellWould my right hon. Friend agree that this is the best form of street lighting, and, incidentally, an answer to the dazzle problem, and recommend that local authorities should install it wherever possible in built-up areas?
§ Mr. Lennox-BoydI think it is rather difficult to dogmatise on this matter. We are in close touch with the local authorities, and there are very many varying views that make it, I think, unwise to lay down a general rule.
