The following photographs were taken on Sunday, 24th October 2010; the three outgoing columns installed on this short cul-de-sac all supported early 1980s' Thorn Beta 5 lanterns.

A small pool of green slime had gathered in the lowest part of this Beta 5's bowl.

By comparison, the Iridium is rated to IP66; in theory, this means that even strong jets of water should be unable to enter the lantern.

The second Beta 5 was in an altogether better condition. Just visible here is the internal identification label - this shows that the lantern is actually a Thorn EMI product, rather than just Thorn.

The Philips logo is visible in the centre of the Iridium's chassis.
