Mile End Road just outside my university has started to lose its early 1990s SGS203s for these strange-looking lanterns which are being retrofitted to the existing columns. As you can see, the other side of the road hasn't been done yet, so I reckon these new lanterns must have only been installed over the last few days. The closest match I've found is a Thorn Oxane, but it looks too slender for the lantern pictured. The reason for their installation looks to be due to CCTV cameras being installed and the construction of a new student residence block just a little further down behind where the photo was taken (due to open in September). The columns also look to being having some sort of signage attached to them, as you can see from the fixtures installed on this column. I have also heard rumours that Mile End Road is going to be renamed the "Olympic Boulevard", as it is the route from Central London to the site of this summer's Olympics in Stratford, so maybe the retrofitting and signage may also be to do with that. It's certainly all go here now for the Olympics!

These have been identified by Sotonsteve as Holophane eStilos (many thanks Steve). I saw these lit on Friday night and can confirm that they run SON (pretty bad really, as replacing the SGS203s, which also ran SON, seems pointless), particularly as some of the SGS203s were replaced with new ones back in 2007 in a casual replacement scheme.
