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".
1886 Great Barrington, Massachusetts demonstration project, a much more versatile (long-distance transmission) transformer based alternating current based indoor incandescent lighting system introduced by William Stanley, Jr. working for George Westinghouse.[8] Stanley lit 23 businesses along a 4000 feet length of main street stepping a 500 AC volt current at the street down to 100 volts to power incandescent lamps at each location.[9]
1893 GE introduces the first commercial fully enclosed carbon arc lamp. Sealed in glass globes, it lasts 100h and therefore 10 times longer than hitherto carbon arc lamps [6][10]
1893 Nikola Tesla puts forward his ideas on high frequency and wireless electric lighting[11][12] which included public demonstrations where he lit a Geissler tube wirelessly.
1994 T5 lamps with cool tips are introduced to become the leading fluorescent lamps with up to 117 lm/W with good color rendering. These and almost all new fluorescent lamps are to be operated on electronic ballasts only.[6]
1994 The first commercial sulfur lamp is sold by Fusion Lighting.
1995 Shuji Nakamura at Nichia labs invents the first practical blue and with additional phosphor, white LED, starting an LED boom.[6]
