2G. Off Horncastle Road, Boston, Lincolnshire On the site of the former Norprint Label factory are three 15 ft (5 m) Revo tubular steel columns supporting examples of the same company's 'Hatfield' post-top lantern. With the factory having closed in 2015, and the buildings demolished, these installations are now abandoned, with one of the three lanterns being in particularly poor condition. Additional Revo columns exist along a portion of the roadway in from the Norfolk Road site, and are supplemented with wooden pole-mounted lanterns; however, all of these are equipped with 55 Watt SOX (low pressure sodium) lanterns of varying types.
The first of the Hatfields is situated only a short distance from Horncastle Road itself.
Several versions of the Hatfield were made, and I understand that the type seen here, with an exposed lamp, was the 'basic' version. Much of the paint applied to the inside of the domed lantern canopy has flaked away, exposing the bare metal beneath.
The presence of an elliptical lamp suggests that these lanterns ran 80 Watt MBF (mercury vapour) lamps. A Revo prismatic glass refractor surrounds the lamp.
The Revo name is present on the column door, which is locked with two standard Revo two-prong bolts. Above the door is a thin strip of metal that is known as a "weather bar", which is supposed to prevent rain from passing into the base compartment.
The same installation again, but pictured from Horncastle Road this time.
Just visible at the lower end of the connecting conduit is a stopper - this would be where a second, symmetrical pipe section would attach on alternative versions of the Hatfield.
A narrow laneway between the houses was home to the second installation.
Here, the refractor is missing, although the lamp remains intact.
The column is embedded in a narrow concrete footway that exists between the road and the house.
Owing to the width of the canopy, a slight "modification" has been required to its back, to prevent it from fouling the wall.
The third installation is at the other end of the lane.
This lantern is in the worst condition of the three, with the canopy, refractor and lamp all missing.
This does allow the construction of the lantern to be appreciated, however.
Heading further south, two further columns are to be seen behind Heras fencing. These are fitted with side-entry brackets, however, which are likely to be original to their installation, in most cases.
The lanterns are later replacements, however - most are CU Phosco P226 / Philips MI 8s, as the foreground lantern here is.
The background lantern is this 1980s' Philips MI 80, fitted with an 'ST7316'-type photocell dating from the 2000s.
One curious installation is this column supporting a triple bracket, with all limbs also supporting a P226 / MI 8. The column shaft has a noticeable lean, although this is unlikely to be because of the brackets and lanterns being top-heavy, especially with the thickness of the steel employed in the old column.
The left-hand example (with a bowl rather full of water) runs a 1980s' Royce Thompson P5 photocell, whilst the right-hand example's photocell is a Zodion SS4.
The column door is missing, though nothing notable appears to remain in the base.
From here back to Norfolk Street, the columns change to wooden poles, with brackets attached to them to support the lights.
Two P226s / MI 8s are installed here, with the right-hand one being another to use an ST7316 photocell, and the other running a Royce Thompson S300PT, which may have been a relatively recent replacement at the time of the factory's closure.
The next pole saw an MI 80 on the left-hand side.
The MI 80's rear bowl clip is missing, with a twist of wire being used as an (unsuccessful) makeshift replacement.
Philips' 55 Watt MI SOX range is complete with the inclusion of a single MI 36 / XGS 104 near the junction with Norfolk Road.
The lack of a barium getter by the lamp's electrodes suggests that a SOX-PSG lamp is fitted. An earth bonding clamp is affixed to the bracket pipe, although the wire attached to it is cut, and doesn't lead anywhere.
