115j - Saltergate, Chesterfield

115j Saltergate, Chesterfield Positioned in the centre of a triangular traffic splitter, and adjacent the affectionately-named 'Doughnut' car park, is a 30 ft tubular steel column supporting a multi-lamp GEC ZD10517 post-top lantern. Very much the last of its kind in Derbyshire, the lantern today runs SON lamps (quantity and wattage unknown) but would have originally operated MBF lamps. At 1140 mm (45″) in length, and weighing in at 30 kg (66 lb 2.22 oz) when the lamp control gear was situated within the lantern, it is a wonder how this lantern was ever fitted in the first place!

Aside from some minor signs of water ingress in the bottom of the bowl, the lantern looks to be in good condition from ground level.

Please resist the temptation to lick your screen at this point; this is not, I repeat, not, an enormous lollipop!

Moving further away from the column, we begin to see the slightly conical nature of the lantern's canopy.

A Royce Thompson one-part photocell can be seen attached to the canopy - although this lantern is unlikely to be running three 400 Watt lamps (the maximum permitted quantity and wattage), if it is, this is also the maximum load that even the highest quality photocells are able to switch.
