In New Orleans, arc lamps were used for street lighting starting in 1881. In 1882, the New Orleans Brush Lighting Company installed one hundred 2,000-candlepower arc lamps along five miles of wharf and riverfront; by 1885, New Orleans had 655 arc lights. [1] In Chicago, arc lamps were used in public street lighting starting in 1887. [1]
For example, in the case of the design of a new street, the urbanist may specify the general layout of the street, including landscaping, surface finishings and urban accessories, but the municipal engineer will prepare the detailed plans and specifications for the roads, sidewalks, municipal services and street lighting.

A commonly used light in the home in the 1960s in 220–240 V countries was a circular tube ballasted by an under-run regular mains filament lamp. Self ballasted mercury-vapor lamps incorporate ordinary tungsten filaments within the overall envelope of the lamp to act as the ballast, and to partially compensate for the red-deficient light ...
The layout of lighting in the home must consider control of lighting since this affects the wiring. For example, multiway switching is useful for corridors and stairwells so that a light can be turned on and off from two locations. Outdoor yard lighting, and lighting for outbuildings such as garages may use switches inside the home.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
In 1900, the name was changed to the International Association of Municipal Electricians (IAME). During the following year, members started to develop standards for wire, cable, and fire alarm boxes—as well as specifications for manhole cover sizes. Thomas Edison is known to have been a member around this time.
