the first light bulb
the first light bulb was created by Thomas Edison. -
a year later
a year later in 1880 Thomas Edison began commercializing his incandescent light bulb -
the big change
The next big change in the incandescent bulb came with the invention of the tungsten filament by European inventors in 1904. -
A better bulb
In 1913, Irving Langmuir figured out that placing an inert gas like nitrogen inside the bulb doubled its efficiency. -
a new upgrade
By the late 1920s and early 1930s, European researchers were doing experiments with neon tubes coated with phosphors. -
the best gets better
In 1974, researchers at Sylvania started investigating how they could miniaturize the ballast and tuck it into the lamp. While they developed a patent for their bulb, they couldn’t find a way to produce it feasibly. Two years later in 1976, Edward Hammer at General Electric figured out how to bend the fluorescent tube into a spiral shape, creating the first compact fluorescent light (CFL). -
perfect for homeowners
Since the 1990s, improvements in CFL performance, price, efficiency (they use about 75 percent less energy than incandescents) and lifetime (they last about 10 times longer) have made them a viable option for both renters and homeowners. -
21st century bulbs
In 2000, the energy department partnered with private industry to push white led technology forward -
more bulbs
in 2010, the department estimated that there were approximately 971 million 60-watt incandescent bulbs in use -
light-bulbs of today
today light bulbs are very different from the past and were come a long way from there, today we have fluorescent led and incandescent bulbs around but they last longer than ever
