'Chelmsford from Springfield Hill'
By John Colkett. Oil on canvas, 1847. This painting shows the railway which had come to Chelmsford in 1843.
The arc lamp was manufactured by Col. R.E.B Crompton at his Arc Works in Anchor Street in c1890.
Crompton placed the arc at the bottom of the lamp, so that no shadow was cast by the casing, giving a steadier light.
