- National Carbon Company Philadelphia Arc Light Carbon, 1886-1900 - Carbon plates, 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 plates, 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 plates virtually obsolete.

- 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.
