154d. High Street, Whitwell Located near the Scotland Street junction are three Abacus 25 ft (8 m) tubular steel columns supporting vintage Thorn 90 Watt SOX lanterns; two of which are Alpha 1s, while the other is an Alpha 9. As the installations resemble the type seen on the previous page, the likelihood is that they are all of the same age, and will have been installed as part of the same scheme. The Alpha 9, therefore, will have been a one-off replacement for an Alpha 1 at some point in the past.
The two Alpha 1s are situated along a tree-lined section of the road.
This example is fitted with a Royce Thompson P42 photocell detector. The Opticell unit has several streaks of bird muck on its exterior, along with a small amount of dirt within the enclosure itself.
The second Alpha 1 falls just below the tree canopy.
Overall, the lantern is cleaner, however. The black lines towards the rear of the Opticell are not cracks but runs of dirt.
The column supporting the Alpha 9 is situated in front of the church of St Lawrence.
This lantern's lamp control gear is situated remotely too.
Thorn Isaro Pro-S 47 Watt LED lanterns on new columns replaced these lanterns in 2021/2.
