That is true for the whole country. A lot of SCHREDER products and particulary Sintra, a lot of INDAL IVA and Viento.
You also find portugese SULNOR and SONERES products, some spannish (CARANDINI, INDAL), french (MAZDA, ECLATEC) and english (GEC) products. There are also very rare PHILIPS HGS 201 and THORN Pilote.

Very nice gallery.
The 5th lantern (Vila De Conde) is an ECLATEC BI 100.
The 13th lantern (Rua do Museu de Artilharia1_s) is an AEC ILLUMINAZIONE AEC2.
The last one (Tv.De Gloria1_s) could be a french B.B.T. OVH 75 but I'm not sure.

Many thanks for your additional info. I must admit I did use your site with its wealth of pictures from around the world to assist with some of the identifications.  

I will update the descriptions, thanks again.

You're welcome

About SCHREDER HM, I have never seen any of them with this bowl in Belgium / NL / France or Germany, I think that you only find this version in Portugal.
When I went in Portugal in 2003, I was very impressed to see all these SCHREDER Sintra. There was, as you said, a lot of Z2 / Z3 and a lot of DM2 / DM 3 too.

Some more spectacular sets of installations found in Barcelona:

Philips Solar-powered LED 'flowers'

Tripod installations featuring very long lanterns!

Thoughts?

Like the LED flowers - quirky. Not so sure on the tripods - makes the street look a little busy/cluttered! I guess those are fluorescent?

I reckon they run fluorescent but I cannot be sure. I like both installations but I think the flowers are less in your face and have a much much sophisticated design.

The tripods wouldn't look right in a lot of UK street scenes. Blackpool perhaps - I mean, if they can fit LCD projectors to street lights and a big mirrorball by the sea, then a few fluorescent tripods is nothing by comparison!

The flowers are strange and truly unique. I wonder how much energy they use to open and close the photovoltaic panels though. At night, their shape has similarities to an Eleco Way, a shape I find aesthetically pleasing.

The 'Flower' lanterns look nice, if they were ever installed over here I would expect to see them in coastal towns or in 'night life' parts of a city.

From streetlighting to radio, dance through the night whilst the streetlights are glowing outside.

Spotted in a trade magazine I get at work from Rhode & Schwarz, was this picture of Cairo Airport control tower that was inaugurated on 21/10/10. Of interest are the Thorn Lemnis lanterns on the columns.

I believe the Lemnis and some other of the rarer Thorn lanterns here, like the Plurio are quite popular overseas. Loving the control tower too, it looks like an anorexic cooling tower!
