The subject of antique lamps is broad, so only lamps with industrial or transportation applications are collected for our purposes. The evolution of lamps for all applications, including domestic, have paralleled one another, changing mostly along with development of new fuels but also new designs aimed to control drip and extend burn time. The oil and grease torches of ancient times were eventually replaced by a succession of oil burning, wick, open pan Cruise, double Cruise, and covered pan lamps, the Betty lamp with its wick guides, brass and steel frog lamps, open flame safety lamps, acetylene and kerosene lamps, carbide lamps and eventually electric rechargeable battery lamps as the 20th Century matured. Tallow candles proliferated in the 17th Century and were still in use in homes, buildings and mines well into the 1900s. Of course there are many rural areas yet on Earth where oil and kerose lamps and candles are still the principle forms of lighting. The carbide lamp was first patented in the U.S. in 1900, and battery lamps, although in use earlier, did not become practical until battery storage and battery life were extended by improvements in the second quarter of the 1900s. Competition to invent an effective Miner's Safety Lamp for use in coal mines was finally trumped by invention of the Davy lamp in 1815. The Davy, Wolf, and kindred safety lamps were used in mines well into the 1900s.
