Light Bulb

The energy we use today at home and office is a bright idea from more than 150 years ago.  
Pioneered in the early 19th century by Humphry Davy, electric lights developed throughout the 1800s and was one of the most influential, great inventions of all times.
Edison and Swan patented the first light bulb in 1879 and 1880. In the mid-1980s, CFLs hit the market. But the drawbacks such as high cost, bulky, low light output, and inconsistent performance made them less prominent. Currently, LEDs offer the best energy savings on the market.
However, the invention of the bulb electrified new businesses. It also led to new energy breakthroughs such as power plants, electric transmission lines, home appliances etc.
