The Lewis lamp would use groups of lamps. The Lewis lamp design proved to have several flaws. To begin, it was really an inferior version of the Argand lamp. The reflector was made of copper with an interior silver plating to reflect light; however, the thin copper would warp under the heat of the lamps to become more spherical than parabolic.
The lamp was first produced by Matthew Boulton, in partnership with Argand, in 1784, and became the standard for lighthouses for over a century. [12] South Foreland Lighthouse was the first tower to successfully use an electric light in 1875. The lighthouse's carbon arc lamps were powered by a steam-driven magneto. [13]

An acetylene gas miner's lamp. A carbide lamp or acetylene gas lamp is a simple lamp that produces and burns acetylene (C 2 H 2), which is created by the reaction of calcium carbide (CaC 2) with water (H 2 O). [1] Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. Portable ...
