202D. Rowan Drive, Brandon, Suffolk Throughout this cul-de-sac are a good number of ELECO HW-918 lanterns; apparently, all still running 80 Watt mercury vapour (MBF) lamps, and all fitted to various types of Concrete Utilities columns and brackets. I was amazed to find so many of these 1960s' installations extant, especially when they will be approaching 60 years old in 2022, and also that MBF lamp production ceased seven years earlier than this.
The first column from Rattler's Road is a 'Byway X' 15 ft (5 m) type; identified by its slightly bellied base section.
This HW-918 uses a transparent, unpatterned Perspex bowl, which has clouded slightly, owing to the heat and ultraviolet light produced by the lamp.
The next column was of the same type.
A noticeable gap was visible between the top of the column and the bottom of the Arc 5 bracket.
This lantern's bowl has become more clouded overall too. Additionally, a slightly ribbed pattern is moulded into the Perspex.
A single column was installed on the first branch road from the main Rowan Drive.
Here, the gap between the column and bracket had been plugged with tape.
The bowl on this lantern was also of the ribbed type seen above, although its transparency was greater.
In the second spur road, Arc 4 brackets were fitted to the two columns that were installed on it.
The Arc 4 type seemed to fit more snugly onto the Byway X column than the Arc 5 type did.
Each of the lanterns is equipped with a three-pin bayonet lampholder, proving that they continue to run mercury lamps.
The second of the two columns on the spur road was located closer to the main thoroughfare.
The lanterns are switched using Telensa radio nodes, with their original two-part photocell detectors having been removed.
The next few columns on the main part of the road featured Arc 4 brackets too.
The bowl on this lantern seemed especially heat-damaged, with visible crazing having developed beneath the lamp. I wonder whether the lantern ran in daylight for a period, with the extended operation having had this detrimental effect. Notice the photo bombing gull in the background too!
At the very end of the road, near a communal parking area, was this column.
The bowl here had clouded excessively too.
This column was situated alongside a 1980s' (assumed) extension spur. Unsurprisingly, the lighting on the extension did not match the design of that on the earlier construction, and is not included here.
The bowl had clouded slightly here, but the lamp remained just about visible within it.
The final column to feature is situated almost opposite the second spur road.
The lantern here also sported a ribbed bowl.
