Headlamps were first developed primarily for mining. Most other occupations could depend on natural light for at least part of each day, but deep pit mining was always carried out far from the friendly light of the sun. For millennia, miners had carried a source of artificial light like a torch, candle or lamp into the mines. They would fasten their light-source somehow to the wall of the shaft and set to work. About 1850 or so, someone in Scotland got the brilliant idea of attaching a small oil wick lamp above the brim of a cap, and the headlamp was born.
The early oil wick headlamps were smoky, sooty and did not give much light. In the early 1900s they were largely replaced by the carbide lamp, which used a cleaner and brighter acetylene flame. The problem was that both oil wick lamps and carbide lamps used an open flame, which could ignite explosive gases like methane which collected in the mines. Several major mine explosions in the early 1900s led to the development of the electric incandescent cap lamp, which came into wide use by the mid 20th century. The electric incandescent headlamp faced competition from florescent technology beginning in the 1970s, and then LED technology beginning in the 1990s.
During this time, there were also significant developments in battery technology. Lighter batteries were able to be installed directly in the headlamp rather than carried on the miner’s belt and attached by a cord to the lamp. In subsequent years, this improving technology has trickled down to the consumer level as well.
Headlamps for Missionaries?
Our church buys birthday presents each year for all of the missionaries whom we support. For many years, I have been the designated buyer. I consider myself to be a somewhat quirky buyer. I feel especially sorry for the missionary wives (they have, for example, received pink Swiss army knives in the past). But I do my best, and always try to keep an eye out for things that the missionaries might find to be useful.
Recently, I was in a hardware store and noticed a display of Coast FL19 headlamps on an end-cap near the checkout. The FL19 looked interesting. Most of our missionaries find themselves working outdoors at night from time to time. I knew from my own experience how useful a headlamp can be in such settings.Continue reading“Gear Review: Coast FL19 Headlamp, by The Novice”
