The following photographs were taken on Thursday, 8th April 2010.
A Thorn Gamma 6 was first from Hindscarth Crescent. This replaced a GEC Z5698U on Friday, 7th June 1996, on worksheet 404975. (This meant that, between the lantern being fitted and the photographing occurring, there was a gap of 13.834 years / 721 weeks, six days / 5,035 days / approximately 121,272 hours.) The reason behind the need to replace the Z5698U is not known. The Gamma 6 was originally fitted with a Hy-lite HL4N photocell; in later years, this cell developed a problem with activating too late every evening and was eventually replaced.
The second column still retained its Z5698U, although a portion of the bowl had been sprayed black...graffiti artists get everywhere! (Actually, the spraying was an attempt to mask out the rear of the bowl in order to prevent light trespass into the windows of adjacent properties.)
The second Z5698U's bowl remained unpainted. This lantern's ballast had been faulty for a few years prior to the PFI - this caused the lamp to produce a noticeable flicker during operation, especially as the lamp aged.
The third Z5698U on here was probably the best of the three on the roadway, in terms of condition.
The new mid-hinged column visible in the background of the previous photograph is seen again here.
Another Gamma 6 could be seen on the footpath to Wenlock Close. Again, this would have replaced a Z5698U in the past. The factory-fitted grub screws on this lantern appear to have been replaced with bolts; perhaps the grub screws were found to be too short to grip the column spigot when the lantern was originally fitted. It is not known why this, or the footpath columns located further down this page, were never painted, when the rest of the columns were.
I had previously photographed this Z5698U when it had been fitted with a 55W SOX lamp. Subsequent relamping sessions on this lantern saw a return to more conventional 35W lamps.
Three new columns on the footpath to Uttoxeter Road replaced the two existing columns:
One of the outgoing columns supported a spigot-mounted Philips XGS 103 lantern - probably the only example in Mickleover (Derby City section), and possibly one of only a very small number installed across the entire City of Derby. Another Z5698U would once have been installed on this column. Seeing as the lighting along this stretch was fed from the nearest column on Uttoxeter Road (and also switched from the control column's cell), the Z5698U is likely to have been supplied without a NEMA socket. I successfully managed to acquire the XGS 103 (which turned out to be badged as an FGS 103) after the column was removed in April 2010. Photographs of the collected lantern can be seen here.
A Gamma 6 was installed on the next column. Yes, this would also have replaced a Z5698U...Interestingly, this lantern retained a reasonably good paint finish to its canopy (albeit covered in bird droppings). Most of the contemporary Gamma 6s had very little paint remaining on their canopies.
The control point column is visible in this photograph - it is the 10M sleeved concrete column in the background. Shortly before the PFI commenced in Mickleover, the control cell developed a fault, which caused it to dayburn. However, as the footpath lanterns are now all individually celled, only the lantern on the concrete column remained lit in daylight.
