The following photographs were taken on the 4th April 2010 - Easter Sunday. All but one of the existing lanterns was mounted at a nominal height of six metres...the replacement lanterns (each running 140 W CPO-TW) are mounted at a nominal height of TEN metres.
The first column from Uttoxeter Road supports a Philips MI 36 lantern. This would have replaced a failed Simplex Aries 55 W SOX lantern in the mid-1990s. The (infamous?) Station Road Thorn Civic 2 lanterns can be seen across the roundabout.
The next few original columns still retained their Aries lanterns.
A new 6 m column, supporting a Thorn Beta 2, was installed around Saturday, 23rd November 2002, at the same time that the adjacent puffin crossing was installed. This column is not listed on the above inventory records; it being newer than the 1997 date from which the records were last amended. For the record, the column was numbered 'DY3178', if anyone is interested! The Beta 2 was always the last to activate of an evening, and the first to extinguish the following morning - the Royce Thompson Monostar 1000 photocell must have lost calibration, as the ambient light levels needed to be almost zero Lux before the lantern would activate.
We return to the original columns now; the Aries pictured is fitted with a Sirebeck S400 two-part photocell (or the detector of one at least):
The next column does not appear to be fitted with a photocell at all, though as it was group-switched from the above installation, this is not surprising.
Another Beta 2 is seen opposite Acacia Avenue. Unlike the example seen on the new column adjacent the crossing, this lantern, as with the MI 36, would have replaced a failed Aries. In fact, all but one of the remaining lanterns along Kipling Drive were fitted with Beta 2s. Coincidentally, the lantern seen below was fitted with a Hy-lite HL4N photocell for many years; this cell also developed a problem with activating too late every evening and was eventually replaced. Note that the new column is situated away from the mature trees!
This outgoing column had a slight lean to it - only when it is seen against the new column (which I am assuming is actually positioned vertically) is this apparent.
And now for something slightly different - the original column here was replaced with an 8 m tubular steel column supporting a Thorn Alpha 4 90 W SOX lantern in about 2003/4.
Another couple of Beta 2s are pictured below:
