Edison, New Jersey

World’s Largest Light Bulb

A giant light 13 feet high shines near Thomas Edison's old lab. 

Thomas Edison was famously dubbed the “Wizard of Menlo Park,” in reference to the New Jersey neighborhood that once housed his historic research laboratory. But while Edison and his original lab are now gone, one monument stands in Menlo Park to this day to honor Edison in the form of his brightest invention.

The world’s largest light bulb is 13 feet all and weighs eight tons. In the night, everyone near the 12-story tower the light bulb rests on can witness its luminescence shining over the residential area below, an unmissable reminder of the modern-day significance of Edison’s invention.

The giant light bulb of Menlo Park was constructed in 1938, just seven years after the inventor’s death, and is encased by 153 individual pieces of Pyrex. During tour hours, visitors will hear music played from a set of nearby speakers, an homage to another Edison invention, the phonograph. If that’s still not enough Edison for one day, next to the tower is a small museum about the famous inventor.
