The incandescent light bulb, incandescent lamp or incandescent light globe is a source of electric light that works by incandescence (a general term for heat-driven … Here are some pros and cons of CFLs vs. LEDs: CFL Light Bulbs. The fluorescent bulb is more efficient in converting electric energy into light than the incandescent light. Tungsten bulbs are usually very less efficient than other forms of lighting. By 1951, the United States of America produced more light from fluorescent bulbs than from incandescent bulbs. Sir Humphrey Davy created the first incandescent bulb in 1802. In 1895, Daniel Moore conducted an experiment that demonstrated emission of white and pink light from carbon di oxide and nitrogen infused bulbs. Fluorescence is the rapid, even immediate emission of radiation, visible or invisible, proceeding the absorption of higher frequency (higher energy, shorter wavelength) radiation such as ultraviolet light. When CFL bulbs were first introduced, they were significantly more expensive than incandescent bulbs. The filament is surrounded by an inert gas such as helium which is kept inside a transparent envelope of glass. Although Thomas Edison is credited with inventing the incandescent light bulb, he was the first one to pursue fluorescent bulbs for commercial purposes. Joseph Wilson Swan in conjunction with Charles Stearn created a lamp with slender carbon rods. These bulbs also require optimum temperatures to work well; they are known to function under capacity when switched on in lower temperatures. Let’s put cost aside for a moment and look at these lighting options based solely on quality and other important factors. Fluorescent bulbs are without a doubt cost effective as compared to an incandescent bulb. The main difference is that the incandescent bulb has a continuous spectrum, which means it includes (in varying percentages) all the frequencies in the visible spectrum. Characteristics and Types of Fluorescent and Incandescent Bulbs, History of incandescent and fluorescent light bulbs, Components of fluorescent vs incandescent bulbs, LED Bulbs: The End of the Lightbulb as we know it? Incandescent bulbs produce a direct light from the heating of the filament whereas the fluorescent bulb produces a secondary light through fluorescent material. Their invention was not commercially viable and was hence not pursued further. Sending a current through such a filament causes a lot of heat to be produced. A traditional incandescent light bulb usually has a life span of about 1,000 hours, while a fluorescent bulb lasts about 9,000 hours. Incandescent and fluorescent are two types of light, which are commonly produced by bulbs. Fluroscent light bulbs are better than incandescent bulbs in almost every way: lifetime cost, environmental impact and energy savings.
