A problem in mining is that the average age of miners is increasing (43.3 years in the US in 2013), and vision deteriorates with ages. [70] LED technology is physically robust compared to a filament light bulb, and has a longer life: 50,000 hours compared to 1,000 – 3,000.
A wheat lamp is a type of incandescent light designed for use in underground mining, named for inventor Grant Wheat and manufactured by Koehler Lighting Products in Wilkes-Barre, Pennsylvania, United States, a region known for extensive mining activity.

Sulfur lamp inside a Faraday cage, which is necessary to prevent microwave radiation leakage from the magnetron which would cause radio interference. The sulfur lamp (also sulphur lamp) is a highly efficient full-spectrum electrodeless lighting system whose light is generated by sulfur plasma that has been excited by microwave radiation.
