What kind of headlamps do miners use?
Portable acetylene gas lamps, worn on the hat or carried by hand, were widely used in mining in the early twentieth century. They are still employed by cavers, hunters, and cataphiles. Small carbide lamps called “carbide candles” or “smokers” are used for blackening rifle sights to reduce glare.
Are miners lamps still used today?
Although its use as a light source was superseded by electric lighting, the flame safety lamp has continued to be used in mines to detect methane and blackdamp, although many modern mines now also use sophisticated electronic gas detectors for this purpose.

A close up of the magnetic lock on a miners’ lamp showing the catch arm and spring-loaded pin released using a strong magnet. To release the pin, a strong magnet must be applied to the base and slowly moved downwards, this pulls the spring-loaded pin down into the catch allowing the catch to be opened.
