Why did electric lamps last longer?
Later improvements used tungsten filament and atmosphere of inert gas which gave even brighter light and lasted longer because gas reduces evaporation of tungsten. Electric lamps were first used only by a few but in time they got wider use and by 1885 it was estimated that around 300.000 lamps were sold only in USA.

Through history, there were many variants of electric lamps but, like we said before, there are three basic types: - Incandescent lamps. They have filament through which electrical current is passed that heats the filament which then emits light.
Why are incandescent lamps banned?
In the last years many countries are passing laws that will ban incandescent lamps because there are more efficient lamps that give same amount of light but consume much less electricity.

When was the first electric light bulb invented?
In 1835, the first constant electric light was demonstrated, and for the next 40 years, scientists around the world worked on the incandescent lamp, tinkering with the filament (the part of the bulb that produces light when heated by an electrical current) and the bulb’s atmosphere (whether air is vacuumed out of the bulb or it is filled with an inert gas to prevent the filament from oxidizing and burning out). These early bulbs had extremely short lifespans, were too expensive to produce or used too much energy.
What made Edison's contribution to electric lighting so extraordinary?
What makes Edison’s contribution to electric lighting so extraordinary is that he didn’t stop with improving the bulb -- he developed a whole suite of inventions that made the use of light bulbs practical. Edison modeled his lighting technology on the existing gas lighting system.
What did Irving Langmuir discover about the incandescent bulb?
In 1913, Irving Langmuir figured out that placing an inert gas like nitrogen inside the bulb doubled its efficiency. Scientists continued to make improvements over the next 40 years that reduced the cost and increased the efficiency of the incandescent bulb. But by the 1950s, researchers still had only figured out how to convert about 10 percent ...
