A close up of the magnetic lock on a miners’ lamp showing the catch arm and spring-loaded pin released using a strong magnet.

The final design was very simple: a basic lamp with a wire gauze chimney enclosing the flame. The holes let light pass through, but the metal of the gauze absorbs the heat. The lamp is safe to use because the flame can’t heat enough flammable gas to cause an explosion, although the flame itself will change colour.
