The electric Christmas lights used on Christmas trees were pioneered by Edward H. Johnson in 1882, building on Thomas Edison’s earlier light strands and later commercialized by Albert Sadacca in 1917.

Who Actually “Invented” Electric Christmas Lights?

When people ask who invented electric Christmas lights , history points to three key names, each doing something slightly different.

  • Thomas Edison (1880)
    • Created the first practical incandescent light bulb and the first strand of electric lights.
    • During Christmas 1880, he strung electric bulbs around his Menlo Park laboratory as a holiday display, visible to passing train passengers.
  • Edward H. Johnson (1882)
    • Edison’s close associate and vice president of the Edison Electric Light Company.
* On December 22, 1882, he hand‑wired 80 red, white, and blue bulbs, wrapped them around a Christmas tree in his New York home, and powered the rotating tree with a generator.

* This is widely recognized as the **first electric Christmas tree lights** , which is why Johnson is often called the “Father of Electric Christmas Tree Lights.”
  • Albert Sadacca (1917)
    • As a teenager in a family novelty-lighting business, he proposed selling colored electric Christmas light strings to the public.
* In the 1920s, he and his brothers helped form NOMA Electric, which dominated the Christmas light market for decades and made electric Christmas lights a common household decoration.

Short Story: From Dangerous Candles to Safe Strings

Before electricity, Christmas trees were lit with small candles attached by wax or pins—pretty but extremely risky, causing many house fires.

Then comes the electric era:

  1. Edison sets the stage (1879–1880)
    • Perfects the practical light bulb in 1879.
    • Uses strands of bulbs as a dramatic outdoor Christmas-season display in 1880, showing how electricity could replace candles.
  1. Johnson decorates his tree (1882)
    • Johnson decides to turn his parlor tree into a showcase of modern tech.
    • He wires 80 walnut-sized bulbs in patriotic colors, wraps them around a tree, and mounts it on a slowly rotating stand powered by an electric dynamo.
 * A visiting reporter describes the glowing tree as “picturesque and uncanny,” noting how striking the new electric effect looked compared to candles.
  1. From luxury novelty to mass tradition (1890s–1920s)
    • Early electric tree lights were expensive; wiring a house could cost hundreds of dollars when the median yearly income was about $750, so only the wealthy used them.
 * Public displays—like President Grover Cleveland’s electric White House Christmas tree in 1895—helped popularize the trend.

 * Sadacca’s affordable colored strings in the 1910s–1920s turned electric Christmas lights into a mainstream holiday staple.
