Describe the history of the lighthouse
A first-order Chance Brothers lens was installed in a 80ft cast-iron tower along with a 12ft lantern, spares, stores etc at a cost of £6,700. William Stokes of Chance Bros installed it. Its six-wick Trinity House Douglass burner produced 47,000 candle power, and was replaced in 1906 with an incandescent petroleum 180,000-candlepower vapour burner, and in 1940 by 4kw electric lamp producing three million candlepower. The optic was replaced in 1974 with an AGA 250mm catadioptric pedestal.
