The light bulb with two prongs is an Edison screw base that has been used since 1879 when Thomas Edison invented them for use in his incandescent bulbs. Unlike the more common household models that take one or three-pronged bases, these were designed specifically to fit into lamps which had threaded openings on top of their sockets to accommodate the Edison’s new invention. The design was so successful that it became the standard for all future lighting fixtures until today where they are still widely used in old fashioned lamps.

It’s generally believed that Edison invented the light bulb and that it had a single prong. The truth is, he didn’t invent the light bulb and there were several different designs of 2-pronged bulbs in use before his patent was even filed. One such design was patented by Henry Woodward and Matthew Evans on January 27 1879.

We all know that light bulbs come in a variety of shapes and sizes, but did you know there are also different types? The type of light bulb you use is important as it can greatly affect the lighting for your environment. One such type is the 2 pronged small bulb. This bulb has an average life span of 2500 hours and emits about 12 watts. It’s perfect for those who want to save energy yet still have a bright enough light.

The light bulb with 2 prongs is the most common in North America. It’s also called a standard-round, bayonet or BA15S lamp. This type of bulb has two (2) flat wires on one side and is typically used for general lighting in an office or home. The shape of the light bulb makes it easy to install, even when space is limited.

There are the old-fashioned, traditional “Edison” type with one prong or filament. These were invented by Thomas Edison in 1879 and they function like a normal bulb. The second type is called the Compact Fluorescent Light Bulb (CFL) which has two prongs/filaments inside it. This newer type was invented by George Inman in 1962 because it uses less energy than an Edison light bulb.
