Traduction de «Lampe à vapeur de sodium » (Français → Anglais) :

10. High intensity mercury vapour discharge lamps, being lamps incorporating a high-pressure arc discharge tube with a fill consisting primarily of mercury, whether such lamps are described as mercury vapour lamps, metal halide lamps, self-ballasted lamps or otherwise when sold, but not including tungsten filament self-ballasted lamps.

‘High-pressure sodium (vapour) lamp’ means a high intensity discharge lamp in which the light is produced mainly by radiation from sodium vapour operating at a partial pressure of the order of 10 kilopascals.

lighting or equipment for the purpose of spreading or controlling light, such as Luminaires for fluorescent lamps, Straight fluorescent lamps, Compact fluorescent lamps, High intensity discharge lamps, including pressure sodium lamps and metal halide lamps, Low pressure sodium lamps

High intensity discharge lamps, including pressure sodium lamps and metal halide lamps

It seems that when there are potentially new good technologies that exist out there and I gave examples, for instance, of someone being able to tweak a ballast on a fluorescent light so that it's only consuming one-third of its energy, or someone using the exhaust from diesel and being able to reconfigure that with a small amount of hydrogen to create output on a diesel engine doubling its horsepower when someone has a great idea within Canada they are told, look, we think this is a great idea and we'll help you a little bit, but we have the belief that the private sector is probably in a better position to do that.

We embarked on a multi-year program to convert street lights to high-pressure sodium vapour, which reduced the city's emissions by 4%. We've embarked on alternative fuel programs for city-owned vehicles and transit buses and conducted trials using ethanol, propane, and natural gas.
