i dont know if u know plz tell me
There were over 10,000 light bulbs on Titanic.
The future is looking bright for them.
Joseph Swann and Thomas Edison invented it independently.The first lightbulb was invented by Thomas Edison in 1879. During his life-time, Edison developed 1093 inventions. Two of his inventions are the motion picture camera and the phonograph!
LED bulbs cost so much because of the amount of life that you get from the bulbs. These bulbs are designed to last for years.
Life didn't exist before the mouse was invented. Plain and Simple! :)
LED bulbs have a longer life and convert more electricity into light than other bulbs but the price to buy them is still very high.
In some light bulbs, the gas used is argon or krypton. These gases help to prolong the life of the filament by reducing its evaporation.
Krypton is used in certain types of incandescent light bulbs because it helps prolong the life of the filament inside the bulb by reducing its evaporation. This allows the bulb to emit light for a longer period of time before burning out.
The light bulb was invented in the United States, with Thomas Edison famously developing a practical version in Menlo Park, New Jersey, in 1879. Today, light bulbs are used globally in homes, offices, streets, and various public spaces, providing essential illumination and contributing to safety and productivity in everyday life. Innovations in lighting technology have expanded their applications, including energy-efficient LED bulbs and smart lighting systems.
