213D. Tan Bank, Telford, Shropshire Situated within the car park for a building now belonging to the Citizens' Advice Bureau is a 20 ft (6 m) Stewart & Lloyd tubular steel column supporting an Advanced Electrical Industries (AEI) 'Brampton' lantern - the forerunner to the Atlas / Thorn Alpha 7. The mounting height is unusual - the Brampton was designed for installation on taller, main road, columns, and could run a 250 - 400 Watt mercury vapour (MBF) lamps. Presumably, the column was installed to provide illumination to the car park after nightfall, rather than general street lighting.
The Brampton is attached to a short outreach bracket with a slight up-tilt.
A glass refractor bowl provides the lantern's optical control.
With AEI's Street Lighting division becoming part of the British Lighting Industries group in 1967 (which would become Thorn Lighting Ltd two years later), this installation was around sixty years old in 2023.
The Brampton would have been a contemporary product with the similar-looking GEC Z8430CM.
