Incandescent lighting has been around since the birth of the sun, but the incandescent light bulb has a much shorter history. The nineteenth century saw the beginning of the incandescent lighting renaissance. Prior to that century, lighting was the from the sun or candles, but by the mid-eighteen hundreds people began to experiment in creating an electric light bulb. Finally, within a year of each other, between 1878 and 1879, Sir Joseph Swan of Great Britain and Thomas Edison of the United States created light bulbs which used a filament inside to generate light. Swan's invention was first, but it is Edison who is remembered by history for the deed. Their designs for incandescent light bulbs were almost identical, and it is still the basis for incandescent lighting used today.
With general point of view, incandescent lighting represents the oldest and the most used form of lighting in homes. Incandescent lamps are so effective that they have been widely adopted around the world for all sorts of lighting applications, from illuminating the inside of an oven to providing safety illumination for parking lots. The mechanics of the incandescent lamp are remarkably simple, and the design has not deviated very much from the earliest prototypes.
Incandescent lamps operate without a ballast. They light up instantly, providing a warm light and excellent color rendition. Incandescent lamps are the least expensive to buy, but because of their relative inefficiency (10-17 lumens per watt) and short life spans(750-2500 hours), they usually are more expensive to operate.
