- National Carbon Company Plain Forced Arc Light Carbons, 1886-1900 - Carbon rods, like these, were used in arc lamps, the first widely used form of electric light in the late 1800s. The lamp's brilliant light, created by an electric arc between precisely spaced rods, effectively illuminated city streets, factories, and other large areas--though falling sparks could prove hazardous. Eventually, improvements in other types of arc discharge lamps made carbon rods virtually obsolete.

Fuller Electrical Company Dynamo, circa 1889
- Arc Lamp - Arc lamps were the first widely used form of electric light. An electric arc created between precisely spaced carbon rods produced a brilliant light that effectively illuminated city streets, factories, and other large open areas. Carbon arc lamps were phased out as a general lighting source during the early 20th century and replaced by incandescent, fluorescent, and gas discharge lamps.

- Wood's System Dynamo and Arc Lamp Testing Department at the Fort Wayne Electrical Corporation, circa 1894 - Established in 1881, the Fort Wayne Electric Corporation manufactured arc lamps, dynamos, and other lighting and electrical equipment. By 1894, the company had survived financial difficulties, a corporate reorganization, and a recent name change. Aided by well-respected electricians, engineers, and inventors, the Indiana company expanded and increased its production efforts. This photograph shows the arc dynamo and lamp testing department.
