Local Urbis Ampera Midis
Three double-arm columns supporting Ampera Midis were installed on the A516 Mickleover bypass on Wednesday, 5th July 2017. The columns were, in fact, being re-installed; having been removed earlier in the year, in order to facilitate a contra-flow system whilst work was taking place on the bypass. When removed, the three columns supported Thorn Pilote T2 150 W SON lanterns, but these were replaced with Amperas, and the bracket outreaches reduced, while the columns were in storage.
These pictures were taken on the day that the columns were reinstalled. At the time, they were awaiting the reconnection of their supply cables.
An almost perfect symmetry is created between the two lanterns.
The left-hand lantern is fitted with a Zodion SS6 photocell.
Meanwhile, a SELC / Westire AcRo is fitted to the right-hand lantern. Both cells are rated at 35 Lux, though neither is required, as the lighting is group-controlled from a nearby feeder pillar.
A convenient crash barrier served to give a slight height advantage when taking this picture.
The logo for Urbis' parent company, Schréder, is cast into the underside of the lantern.
The lanterns run 64 LEDs each. The slight 'fog' visible to the right of this picture is the mesh of the bridge structure, through which, the picture was taken.
This view demonstrates the difference between the outreaches on the re-installed columns compared to those that were not removed for the scheme.
A length of wide plastic ducting surrounds each of the re-installed columns at ground level. As can be seen, this column's base was completely devoid of equipment when the picture was taken.
Sections of the A61 between Alfreton and Chesterfield were relit using Ampera Midi lanterns attached to 10 m columns in 2017. Along this section of road, there existed a 10 m column with an exceptionally long outreach that supported a GEC Z9554M 135 W SOX lantern, owing to the column being situated at the rear of a bus lay-by. By comparison, the new lanterns are all mounted directly to the column spigots.
A label affixed to the underside of the lantern provides information on identifying the lantern configuration from ground level; the code representing:
U = Urbis lantern
94 = Wattage
M2 = Lighting class
Some of the columns were new enough to be re-used for this scheme; this column is such an example - a WRTL Arc 150 W SON-T lantern used to be installed here.
The section linking the column to the lantern (and securing the lantern to the column spigot) is detachable - this allows different adaptors to be fitted, depending on the diameter of the column or bracket to which the lantern is being attached. This also allows the lantern tilt to be adjusted.
As you may expect, the Midi is the 'middle' size of the Ampera range, and looks in proportion when installed atop a 10 m column.
A distinctive feature of the Ampera is its flat front section, and bellied rear.
Elsewhere on the A61, in the Little Eaton area, 94 W Ampera Midis were attached to 10 m conical aluminium columns.
The new columns are installed in an 'opposite' arrangement, owing to the width of the carriageway at this point.
All are installed post-top.
A plug designed for releasing any moisture that has built up in the rear section of the lantern is visible when viewed from below.
The Amperas continue into Little Eaton village itself, though standard tubular steel columns are installed here.
A rather sharp positive tilt is employed to two consecutive lanterns at this location.
