WRTL 'Pathfinder' 2400
Lantern acquired in October 2005.
WRTL/Industria join the 'curious lantern name' group with this amenity fitting, though I suppose that the name is quite appropriate - after all, the light emitted from the lantern could help someone to find a path! This example was removed from a Housing Association column in Bembridge Drive, Alvaston, and was replaced with two 150 W metal halide floodlights in order to provide improved colour rendering and brightness for some nearby CCTV cameras.
Probably the most noticeable feature of this lantern is the prismatic refractor bowl, which has several different patterns moulded into it to ensure maximum light output. The lantern was installed in August 2002 according to a date on the inside of the canopy.
The canopy is held in place with a small plate located on its underside. Once this is removed, a small anti-clockwise turn releases it, and then to completely remove it, it simply needs to be lifted off.
Notice the small black flies in the recess where the column fits - there were more in the lantern itself as the sealing gland around the cable had not been tightened when the lantern was installed. Luckily the lantern is very easy to clean, and so they were gone in no time!
The gear tray is held in the centre of the lantern by four lugs that push into spaces on the bowl.
The lantern was powered up on Saturday, 11th March 2006. The prismatic bowl contorted the light pattern in just about every conceivable way! The SS11N minicell was found to be faulty, and so was changed for a SELC 849.
The following couple of photographs show a Pathfinder in-situ:
I cannot remember what lantern was fitted to this column prior to the Pathfinder being fitted; although it was probably a more 'traditional' post top - such as a GEC Z5698U or a Thorn Gamma 6. The column in the background, also with a Pathfinder fitted, originally had a Beta 5 installed. Curiously, this column now supports the Pathfinder's sister lantern, the Arc, which isn't remarkable in itself; however, perhaps what is, is the fact that it runs a 100 W SON-T lamp - this is overkill for a 5 m column installed on a footpath!
The Pathfinder, and its column, were removed in March 2010, following replacement work for the Street Lighting PFI.
