* 1874 [[Alexander Lodygin]] patents an [[incandescent light bulb]].
* 1875 [[Henry Woodward (inventor)|Henry Woodward]] patents an electric light bulb.
* 1876 [[Pavel Yablochkov]] invents the [[Yablochkov candle]], the first practical carbon arc lamp, for public street lighting in Paris.
* 1879 (About Christmas time) Col. [[R. E. Crompton]] illuminated his home in [[Porchester Gardens]], using a primary battery of Grove Cells, then a generator which was better. He gave special parties and illuminated his drawing room and dining room. Source: Practical Electrical Engineering, Newnes. Article entitled "The Development of Electric Lighting".
