The invention of electric light began long before Thomas Edison patented the incandescent lightbulb in 1879. In fact, British inventors demonstrated that electric light was plausible with an arc lamp as early as 1835. Edison is often credited with inventing the first light bulb because he took these discoveries, improved them and came out with the first commercially practical incandescent light bulb.
Since 1835, electric light has evolved to produce different forms of light, including incandescent, fluorescent, halogen, light-emitting diode (LED) and compact fluorescent.
1976 – Edward E. Hammer invented the compact fluorescent light (CFL) after discovering a way to bend fluorescent tubes into a spiral shape in response to the 1973 oil crisis. These bulbs last 10 times longer than incandescent lights and use 75 percent less energy.
In the past several years, lighting technology has vastly improved, helping consumers reduce electricity costs and significantly lower carbon emissions. According to a Goldman Sachs report, “The rapid adoption of LEDs in lighting marks one of the fastest technology shifts in human history.” We have more than 180 years of lighting history and research to thank for such drastic improvements.
