chemiluminescent. The light is produced entirely by the mixing of chemicals. There's no danger of an electrical spark igniting the gas if the bulb broke or from wiring or switch-contacts..
Another alternative, not in the list, is light-pipes, sending light from light-sources outside the building or mine into the dangerous area down bundles of glass optical fibres.The light source could be sunlight or artificial light.
