The GC3240F looks similar to a British Eleco Lunar PT1007. However, the NX250 looks just like an Eleco-way post-top. In Britain there was a bit of an overlap between Eleco and Philips in the 1960s and 1970s, with some products sold under both Eleco and Philips brand names, such as the GR100/150/200 (MA9/5/6) and SR304 (MA3). A similar thing happened between Phosco and Philips, with certain products also being sold under both Phosco and Philips brand names, such as the P223/4/5/6 (MI5/8) and P400 (MO62).

In my city there is an experimental installation of LED street lighting, consisting of 45w Philips Fortimo LED modules which give out 2000 lumens of light. The light output is appalling, and it is the worst lit street in the city. Consider that 35w CDM-T gives out 3300 lumens of light, and 42w PL-T gives out 3200 lumens of light, for approximately the same power consumption.

From what I have seen LED technology still needs to develop a lot more, because it is presently less efficient than discharge lamps such as ceramic metal halide, compact fluorescent, and high pressure sodium. The 45w Philips Fortimo LED modules used only achieve an efficacy of around 67 lumens per watt, which is terrible by modern standards.

GEC Z842x series luminaire. If the luminaire had a flat glass enclosure rather than an acrylic bowl enclosure it would be a Z8422. I am not sure of the product code for the integral geared acrylic bowled version.

We have a skeletal network of wide motorways rather than an extensive network of narrower motorways, which is something rubbish about Britain, and we seem to be adopting an approach to lighting of "more is better". Taller columns, closer spacing, brighter lamps. Lighting is getting quite excessive in places.

Merci! What about French lanterns though? Open bottomed lanterns are very difficult to find in Britain unlike France!

Health and Safety is more excessive in Britain I believe. We are even starting to see hinged columns below doomestic overhead power lines that run along streets, even though they are relatively low voltage and the wires are fully insulated.

Low Pressure Sodium is quite popular in Britain, although it has now effectively been outlawed by British Standards, because the lamps have a colour rendering index of less than 20. Low pressure sodium is still used in some areas to replace failed old low pressure sodium luminaires, but very rarely do you now see a new street lit or old street relit fully with low pressure sodium. Low pressure sodium is in decline.
