The miner’s safety lamp was designed by the mining engineering genius Sir Humphrey Davy, to withstand handling in arduous conditions. Sailors too have found their virtues invaluable: our replica miner's lamp is wind resistant, and has quarter-inch (5mm) glass. Though illumination is limited, it is an ideal night light on boats which must conserve battery power. Measures 26cm tall. Note: This is not an original Type Vale miner's lamp but a reproduction.
