The following photographs were taken on Sunday, 11th March 2012.
First from the Abbey Lane junction was this 6 m column supporting a Thorn Beta 2 55 W SOX lantern.
The Beta 2 featured the slightly more unusual polycarbonate bowl - evidence of this is the slightly cloudy appearance to the plastic. The Beta 2 seen here was saved from the skip and now resides in a private collection.
The replacement lanterns installed along here are SUGG 'Camberwell' designs; all running a 70 W CDO-ET lamp.
A 5 m column supporting the Beta 2's little brother, the Beta 5, followed. The new columns are not quite 5 m in height, although the position of the lamp within the lantern sites it at almost 5 m from ground level.
The new lighting makes a marked difference along the road, both in terms of its style and the colour of the light emitted.
An elderly Stewart & Lloyd tubular steel column was next for the chop - this too supported a Beta 5, albeit an earlier variant.
An identical setup followed for the remaining few columns along the road. Rust was showing on this column's door.
The lantern's bowl was in an equally poor condition - a large crack had formed down the centre, and a wonderful collection of assorted dirt had gathered to the back.
The replacement columns were cast at a foundry in Huddersfield especially for this scheme. They replicate the a style of column that still exists in the grounds of the nearby St Matthew's Church - this was made by a Derby-based foundry in 1865. The lantern fitted to this column is very similar in appearance to the Camberwell, and could be an earlier version of the design.
Just in case you doubted me over what lamps were fitted in the new lanterns, here is your proof:
The door from an (octagonal) Stanton 1805 column had been fitted in place of the column's original door and had been secured using a "Tamtorque" band owing to the different locations of the locks on both column types.
Miniature photocells control the operation of the new lanterns.
The SC1000 photocell fitted to this Beta 5 is of the type employed from the commencement of the PFI in 2007 until September 2010.
