miner's lamp
Pit worker's torch
A miner's lamp is a portable light source designed for underground mining, where open flames risk igniting explosive gases.
The safety lamp, developed in the early 1800s, enclosed the flame in fine wire mesh that prevented ignition of surrounding air.
Modern versions use battery-powered LEDs mounted on helmets: The glow of miner's lamps bobbed through the tunnel.
