There is something beautiful about light bulbs and the way they were packaged back in the day when incandescent bulbs were new. We take it for granted that bulbs have always been with us and always will.

Did you know the invention of the incandescent light bulb starts in the early 1800s. In 1809, an English chemist, Humphrey Davy, began testing practical incandescent light sources using a high power battery to induce current between two charcoal strips. The current flowing through the two charcoal strips produced an intense incandescent light, creating the first arc lamp. In 1820, Warren De la Rue made the first known attempt to produce an incandescent light bulb. He enclosed a platinum coil in an evacuated tube and passed an electric current through it. The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain less gas particles to react with the platinum, improving its longevity. Although it was an efficient design, the cost of the platinum made it impractical for commercial use. For more history go here.
