At the end of the 19th century, many towns and cities were lit up by powerful electrical lamps placed on towers up to 300 feet (90 metres) high.
The arc lamp - the first electric light and the predecessor of Edison’s incandescent light bulb - was extremely bright and much more energy efficient than other lighting technologies from those times.
The lamps were too strong for indoor use, but they were regarded as the future of municipal lighting. Especially in the United States, many cities and towns were illuminated as if they were immense sports stadiums.

The incandescent light bulb is abused by environmentalists – but the alternative will only raise energy consumption. More and more, compact fluorescent lamps are considered to be an interim technology, awaiting the arrival of Light Emitting Diodes (LEDs) and Organic Light Emitting Diodes (OLEDs).
At the moment, LED technology is no competition for the incandescent light bulb. However, it can be considered a worthy improvement of another technology: neon lights. Whether or not white LEDs will finally arrive, the success of coloured LEDs is a fact. Though some of them are definitely useful, they all introduce lighting in places and situations where there was no lighting before.
