This electric cap lamp was made by the Concordia Electric Co. The lamp was powered by a battery enclosed in a self-locking steel case worn on the miner’s belt. A flexible cord, protected by a steel spring where it comes out of the battery, connected the battery to the cap lamp. This lamp is marked as permissible by the U.S. Bureau of Mines, and has an added cord for plugging into an electric outlet. This picture show the lamp attached to the miner’s cap.
