[8] After 1969, the Coast Guard removed lighting equipment from the original buildings and replaced them with a single directional light on the beach.
The lens was finally installed and the light lit in 1908. It was the last lighthouse to be constructed on the Chesapeake.

The heat generated by the arc and electrodes then ionizes the mercury and metal halides into a plasma, which produces an increasingly brighter white light as the temperature and pressure increases to operating conditions. The arc-tube operates at anywhere from 5–50 atm or more [8] (70–700 psi or 500–5000 kPa) and 1000–3000 °C. [9]
