Calgary, often called 'the most progressive city in Can- Are We Paying Too Much For Our Street Lighting? ada," came up with the best answer yet and now boasts one | complete mile of the revolu-| tionary Canadian General Elec- | tric Lucalox street lighting. | Installed on McLeod Trail, one) of Calgary's main thorough- fares. this ultra-modern lighting |system became the first per- manent installation of its type | anywhere in the world. The problem was to provide adequate illumination for the 90- | foot roadway between 42nd and 58th Avenues. This portion of | McLeod Trail is fronted with) car lots, motels and other busi- | nesses and broken by many ac- | | cess roads and driveways. the new light source called Lucalox, is termed by Canadian General Electric | | the most significant advance in | lighting since the introduction of | fluorescents. | Lucalox has an_ efficiency | never previously obtained from general lighting sources. One' 400-watt Lucalox lamp produces as much light as all the bulbs in an average household, and has a rated life of 6,000 hours, The pencil-thin light-producing arc tube is inside a slender, elliptical-shaped bulb measu! only 2% inches in diameter 934 inches long, including the screw base. Canadian General Electric en- gineers point out that street lighting with Lucalox bulbs pro- duces 50 per cent more light, at the sane operating cost, as those now using mercury vapour lamps. Economy is effected | through reducing the number of bulbs, fixtures, poles and wiring needed to light a specific area, In the Calgary installation, using 1,000 - watt clear mercury lamps would have meant stage gering the lighting poles 80 feet apart. Using 400-watt Lucalox bulbs in a new Canadian Gem eral Electric luminaire fixture, they were able to stagger them 120 feet apart, using only 4 units. This Calgary trial is being watched closely by lighting exe perts in many parts of the world and is already winning wide acclaim, Indications are that it has already saved Calgary tam payers 2 per cent on capital costs, plus an estimated saving of about 60 per cent in electrie power costs. fr CLEAR-UP The Choice of Quality Builders and Homeowners STONE WALLING FIREPLACES PLANTERS BARBECUES and Free Estimate on Materials S AWDON'S BUILDING SUPPLIES HOME IMPROVEMENT CENTRE 244 Brock S., Whitby Phone 668-6612 the best in LAB PICTURE With this EXTRA | High Performance | TV antenna and be veady for VIVI COLOUR at Its best.
