Local Industria Arcs

The Arc first appeared in Derbyshire in 2004 - it wasn't until about a year later that the lantern was first used in Derby City, however. The lantern can be mounted both side entry and post top - both types are shown on this page. SON lamps are the order of the day in Derby City; whilst compact fluorescent and metal halide examples can also be seen in the wider county of Derbyshire. The smaller Arc 80 can accommodate lamps up to 150W; whereas the larger Arc 90 can be fitted with lamps up to 600W - though 250w is the maximum used in Derbyshire.

These Arcs with 42W PL-T lamps are mounted on 5m columns at a development in Buxton. A 55 Lux Oasis 2000 cell is employed.

More 5m 42W Arcs here - seen on a rainy January night. Notice that the second lantern along has a lamp with a lower colour temperature than the other two.

These 42W Arcs are on (what was when the photograph was taken) a new development in Belper. Although 42W lamps will 'work' at 6m, the output appears quite dim to the human eye.

Also in Belper are these Arcs running 57W PL-T lamps at 6m. Unusually, the installer has gone for curved glass bowls, rather than the 'standard' deep polycarbonate bowl. The columns lead onto what was the site of the Parks Secondary Modern school - this access road was the original driveway into the school.

The same installation as seen at night.

This Arc has been retro-fitted to a column which once supported a Thorn Beta 5. Notice how it looks a little too big for the bracket!

This Arc is literally just around the corner from the previous one. At the time of photographing, it had been vandalised.

This post-top Arc replaced a GEC Z9538 when the column it was on was damaged in a collision. The SS3DR cell was faulty from when the lantern was first powered up and was duly changed.

This post top Arc is fitted to a drop-down column and will soon replace this pole-mounted GEC Z9532. Oddly, an elliptical lamp has been fitted in the Arc - presumably to reduce glare in the narrow footpath. A Beta 5 was originally fitted to the new column - this photograph was taken soon after the changeover.

This Arc was used to replace a vandalised Z5698U. Click here for more details.

The Arc provides a good cover of light when in use.

Another couple of photographs of Arcs in Buxton - this 6m 70W example is adjacent to the development mentioned further up this page. The new column has been installed to replace the 5m column and Beta 5 - when I visited, the service had all ready been transferred to the new column (hence the temporary safety barriers surrounding the area).

This Arc in Matlock is mounted to a 6m column with a diameter wider than the standard 76mm as it also carries a School Safety Zone sign and a twin amber flashing unit - the wider diameter is necessary due to the added weight and windage being placed on the column by this equipment.

At the junction to the new development where the 6m 57W PL-T Arcs (as seen above) are used,  two new 8m columns running 100W SON-T Arcs have been installed. Previously there were two 6m concrete columns with 55W SOX lanterns here, but the higher columns were required due to the width of the road at this point.

This 100W Arc was located in Markeaton Park. It was removed a few weeks after these pictures were taken and replaced with a Thorn Alpha 8 running a 250W MBF lamp.

This wall-mounted 150W SON example is in Bolsover.
