Local CU Phosco P862s

The winner of the Lux Award for Exterior Lantern of the Year for 2016, the P862 lantern first made an appearance in Derbyshire around the middle of the same year, and complemented other CU Phosco LED offerings that had already been installed around the County in considerable numbers in earlier years.

The first P862 examples that I spotted were attached to 8 m columns on the main road passing through a new housing development off Rykneld Road in Littleover (although, technically, it falls within Burnaston parish).

 

This close-up view of the lantern reveals that only the front part of the lantern's optic area is equipped with LEDs; the rear section is blanked off.

 

Four rows of eight LEDs (a total of 32) can be seen within the lantern. As well as the positive and negative DC supply wires, two white wires also connect into the circuit board; these (perhaps) allow a dimming module to operate. Notice that there is a gap between the 'control' and 'optical' parts of the lantern; bridged only by a narrow central section that accommodates the panel wiring. A helpful label attached to the lantern's spigot entry informs us that the lantern's overall power consumption is 46 W, with 'R2' referring to the beam configuration for this particular lantern.

 

A Royce Thompson Oasis 2000 photocell is fitted. An interesting point to note that the photocell's transparent plastic enclosure is a raised conical shape - the original units of this type produced in the mid-late 1990s featured enclosures of the same shape before becoming less pointed in the 2000s. Perhaps, Royce Thompson has standardised on this enclosure shape for all of their photocells now.

 

P862s fitted to 10 m columns were installed on the westbound A516 entry/exit slip road at Mickleover in March 2017 - the slip road having undergone slight realignment as a result of a roundabout being constructed on the A516 itself, in order to provide access to a new housing development on the opposite side of the road. It was from this slip road that two Thorn Pilote T2 150 W SON-T lanterns were saved into my collection, following the removal of their columns in January of the same year. At the time of photographing, the new lighting was connected to a temporary supply obtained from the existing street lighting's supply; hence, the presence of a ducted cable to the bottom-left of the picture.

 

This time, both portions of the optical unit are in use; owing to the brighter light levels needing to be obtained for this busier road. Once again, Oasis 2000 cells are fitted. These appear to be rated at 35 Lux.

 

The doubling of the boards means that this lantern runs 64 LEDs; presumably, this means that the total wattage will be around 92 W - there is no helpful label attached to this lantern's spigot entry, and the label on the underside of the lantern is too small to read from ground level, even when viewed at my camera's maximum zoom.

 

This view demonstrates the means by which the lantern attaches to its column or bracket, along with the adjustable tilt mechanism.

 
 

 

P862s were fitted to new double-arm columns on the A516 itself in early May 2017.

 

The slim profile of the lanterns and relatively narrow bracket diameters make for a very aerodynamic installation.

 

What appear to be Zodion SS4D photocells are fitted to these lanterns, even though the lighting is group-controlled from an existing feeder pillar located a little further along the bypass.

 

The right-hand lantern is a mirror image of the left.

 

The new columns and brackets are made by Mallatite.

 

Once again, 64 individual LEDs are fitted.

 

This close-up of the label confirms the LED quantity, as well as filling in the blanks over some of the other attributes: the LEDs are "neutral white" in colour, have a 700 mA running current (equalling a total of 136 W) and do not have a dimming regime. The lantern was made on the 9th January 2017 and was supplied with 14 m of 2.5 mm2 cable.

 

The installations take on the appearance of wings when viewed from the nearby overbridge.

 

The roundabout itself began to have columns installed on Tuesday, 13th June; these columns being passively-safe 12 m tapering aluminium products.

 

The lanterns were fitted a few days later.

 

Only the columns on the 'closed' side of the road were erected at this time.

 

The lanterns appear to be the same LED configuration once again.

 

Owing to the ground surrounding the new columns in their passively-safe cylinders not having been backfilled at the time, the planting depth labels were still visible on the column shafts.
