LIGHT BULBS

Light bulbs have been around since the late 18th century when Ebenezer Kinnersley demonstrated heating a wire to incandescence light bulbs became more commercialized in the 19th century when Joseph Swan began working with carbonized paper filaments in an evacuated glass bulb.

By 1860, he was able to demonstrate a working device but the lack of a good vacuum and an adequate supply of electricity resulted in a short lifetime for the bulb and an inefficient source of light.

Yes this is actually true! Don’t believe us check Wikipedia.
