The final bearer of the torch runs towards the cauldron, usually placed at the top of a grand staircase, and then uses the torch to start the flame in the stadium. It is generally considered a great honor to be asked to light the Olympic Flame. After being lit, the flame continues to burn throughout the celebration of the Olympics and is extinguished at end of the closing ceremony of the Games.
For the ancient Greeks, fire had divine connotations — it was thought to have been stolen from the gods by Prometheus. Therefore, fire was also present at many of the sanctuaries in Olympia. A fire permanently burned on the altar of Hestia in Olympia.
During the Olympic Games, which honoured Zeus , additional fires were lit at his temple and that of his wife, Hera. The modern Olympic flame is ignited at the site where the temple of Hera used to stand. Fire did not appear at the modern Olympics until Dutch architect Jan Wils had included a tower in his design for the Olympic stadium for the Amsterdam Olympics and came up with the idea of having a fire burn throughout.
On July 28 , an employee of the Amsterdam electricity board lit the first Olympic fire in this so-called Marathontower , known as the " KLM 's ashtray" by the locals. The idea of an Olympic Flame was met with enthusiasm, and was incorporated as a symbol of Olympism. German sports official and sports scientist Carl Diem conceived the idea of an Olympic torch relay for the Summer Olympics in Berlin.
More than 3, runners carried the torch from Olympia to Berlin. German track and field athlete Fritz Schilgen was the last to carry the torch, igniting the flame in the stadium.

Incandescent light bulbs have tungsten filament in a glass bulb in atmosphere of vacuum or of gas xenon, argon or krypton; noble gases that reduce evaporation of filament and with that make lamp last longer.
Types that are used in flashlights are of white high-power kind. They are much more efficient than incandescent light bulbs and last longer.
As a source of energy, they mostly use batteries but the can use accumulators or super-capacitors, they can be charged by solar power or mechanically. Depending on planed use they are made in myriad of shapes. Nowadays most use LEDs , which work slightly differently. In , the first dry cell battery was invented. Unlike previous batteries, it used a paste electrolyte instead of a liquid. This was the first battery suitable for portable electrical devices, as it did not spill or break easily and worked in any orientation.
Sometimes the electricity comes from a small generator instead of a battery. Hundreds of years ago, people used candles for all indoor light. This was expensive, and once the candle was gone, you would have to buy or make a new one or be stuck in the dark.
