At our annual village quiz night, I caused a bit of a scene. The question was simple enough, ‘Who invented the light bulb?’ The answer, according to the compere, was Edison. ‘Well actually’, I’m afraid I couldn’t resist piping up, ‘electric lighting is much older’. During the 19th century 2 types of electric lamps were developed; the incandescent lamp (light created by passing the current through a filament) and the arc lamp (where the light is created by electricity leaping the gap between electrodes).  

Humphry Davy first demonstrated an arc lamp in 1806 but the blinding light was impractical and could not be powered for more than a few minutes. He was a dazzling speaker and he hosted lectures which became major social events in London. However, it took quite some time for electricity to become a practical form of lighting.

It was Joseph Swan, an inventor from Sunderland, who developed the first practical lamp and led the way in early electrical lighting. Swan supplied arc lamps to light the Picture Gallery at Cragside in Northumberland in 1878, the first house to be lit by electricity, and for Mosely Street in Newcastle, the first electrically lit street in 1879. (1879 was, incidentally the year Edison first demonstrated his own lamp in the USA). In 1881 Swan opened Benwell Lamps, the world’s first light bulb factory.

So if Edison didn’t invent the light bulb, why he is famous for doing so? Well, true to his American roots, he took it to market! He successfully registered patents and tried, but failed, to sue Swan, so then took him as a business partner instead. In 1883 Edison and Swan was formed and created bulbs which were cheaper and lasted longer than anyone else’s. Edison was a highly successful spin doctor and his vision of centralised electricity supply stations was paramount to his success.

Throughout the Victorian era electricity remained extremely expensive leaving gas as the popular choice for most middle-class households. Wider availability of electricity coincided with the arrival of the Arts and Crafts influence and, from the Edwardian period we begin to see a proliferation of new ‘electroliers’ replacing gas fittings (gasoliers).


It is not until after the First World War that electricity found its way into homes on a large scale. The metal filament lamps had been perfected in 1911 and the Electricity (Supply) Act passed in 1926, led to the establishment of the national grid. We finally had clean, safe lighting at the flick of a switch; no more fumes or bad smells.

So Edison may not have invented the light bulb; Davy can lay rights to that claim. He didn’t even design the first practical light bulb or register the first light bulb patent; that was down to Swan. What Edison does deserve credit for is making electric lighting available. When he saw he was trailing Swan he cleverly joined forces with him (if you can’t beat them, join them!) and developed the supply chain. He owned a power company, later known as General Electric, and, let’s face it, without a source of electricity to light it, a light bulb is just a bulb.

    Edison was not the only inventor trying to make a light bulb. England’s Joseph W. Swan, a chemist, experimented in the 1850s and 60s with carbon filaments. His early efforts failed
    however, because the vacuum pumps of those years could not remove enough air from the lamps. By the mid-1870s better pumps became available, and Swan returned to his experiments.

    By late 1878, Swan reported success to the Newcastle Chemical Society and in February 1879 demonstrated a working lamp in a lecture in Newcastle. His lamps contained the major elements seen in Edison’s lamps that October: an enclosed glass bulb from which all air had been removed, platinum lead wires, and a light-emitting element made from carbon. Why
    then is Edison generally credited (outside Britain) with inventing the light bulb?

    Like other early inventors, Swan used a carbon rod with low electrical resistance in his lamp. Due to the relationship between resistance and current, a low resistance element required lots of current in order to become hot and glow. This meant that the conductors bringing electricity

    to the lamp would have to be relatively short (or impossibly thick), acceptable for an experiment or demonstration, but not for a commercial electrical system.

    Made from an arc-lamp element, Swan’s carbon rod gave off light but did not last very long. Gasses trapped in the rod were released when the lamp was activated, and a dark deposit of soot quickly built up on the inner surface of the glass. So while Swan’s lamp worked well enough for him in a demonstration, it was impractical in actual use.

    Edison realized that a very thin “filament” with high electrical resistance would make a lamp practical. High resistance meant only a little current would be required to make the filament glow and allow much longer copper lines of modest size to be used. Edison’s Bristol-board lamps of December 1879 lasted about 150 hours, and his bamboo lamps of early 1880 lasted 600 hours.

    It is for this realization about high resistance, and for his conception of the lamp as only one part of an integrated system, that Edison is generally credited with inventing the first practical incandescent lamp. As mentioned, Edison also put significant effort into the creation of the large scale electrical generation, manufacturing, connection, and wiring systems necessary to make use of the lamp.

    Swan did not lose out entirely however. While it appears that he never sent
    the letter that he wrote to Edison (cited above), his patents were
    strong enough to win in British courts. After another lamp maker lost a
    patent suit to Swan, the Edison interests decided to negotiate rather
    than risk losing a suit of their own.

    In 1883 the Edison & Swan United Electric Light Company was
    established. Known commonly as “Ediswan” the company sold lamps made
    with a cellulose filament that Swan had invented in 1881. Variations of
    the cellulose filament became an industry standard, except with the
    Edison Company. Edison continued using bamboo filaments until the 1892
    merger that created General Electric — and that company then shifted to

    The lighting is fantastic and it so good for me to see this. I’m upcoming electrition in ghana/accra and it will help me to choose light carefully.
