The exact number of light bulbs invented is difficult to determine, as many inventors and companies have created various designs and types over the years. The most notable early versions were developed by Thomas Edison and Joseph Swan in the late 19th century. Since then, innovations have included incandescent, fluorescent, halogen, and LED bulbs, among others, resulting in thousands of unique models and variations. Each type has further adaptations, making the total number of light bulb inventions quite extensive.
352 There are six different types of light bulbs invented as of December 27, 2012. They include the incandescent light bulb, the halogen light bulb, the fluorescent light bulb, the high-density discharge lamps, LEDs, and sodium lamps.
Fluorescent light bulbs have been shown to use one quarter less energy than a typical incandescent light bulb and they last longer. You will save money on utility bills (despite the initial cost) and will help save the environment by using bulbs which last longer.
When bulbs are connected in series to one another, a failure of one bulb will open the circuit and the remaining bulbs in the line will go out because they have no power. However, bulbs in the line preceding the failed bulb will continue to be lit because their source of power has not been interrupted. When bulbs are connected in parallel, a failure of one bulb will have no effect the remaining bulbs because the power is not routed through any single bulb alone.
Incandescent light bulbs have been around since the late 19th century, with Thomas Edison famously developing a practical version in 1879. However, earlier prototypes existed, with Sir Humphry Davy creating an electric arc lamp in the early 1800s. Over the years, incandescent bulbs became widely used for residential and commercial lighting until the rise of more energy-efficient alternatives in recent decades.

Thomas Edison invented light bulbs
Flower bulbs have been around for hundreds of millions of years. They were part of flower evolution.

Before 1879. 1879 was when it was invented

The first person who invented light bulbs was Sir Joseph Swan. He was a British chemist and physicist. His house was the world's first place to be illuminated with light bulbs.
well, oil lamps cause fires in wood houses, electricity had been discovered, not invented, discovered by Benjamin Franklin, and Thomas Edison invented a light source to benefit from it
Dark ;) hahaha.
