English: In 1878 the Victoria Embankment (near Westminster Bridge), which was previously lit by gas, was illuminated with Jablochkoff Candle arc light alternating with the original gas standards to show the difference. Supply came from Gramme AC generators. The prime movers were steam engines made by Ransomes, Sims and Head of Ipswich. In June 1884, gas lighting was re-established as electricity was not competitive. The original lighting standards are still in situ.
