You probably think Thomas Edison did it. Most people do. It makes sense, right? The guy who basically commercialized the lightbulb should be the one responsible for the twinkling strands currently tangled in a plastic bin in your garage. But the history of when were christmas lights invented is actually a weird mix of marketing stunts, high-voltage house fires, and a very bored vice president at the Edison Electric Light Company.
It wasn’t a sudden "eureka" moment.
Before 1882, if you wanted a "festive" tree, you strapped open-flame wax candles to dry pine needles with melted wax or pins. It was essentially a controlled house fire waiting to happen. People kept buckets of water or sand nearby. Insurance companies eventually started refusing to pay out for fires started by "illuminated trees." It was a mess.
The 1882 Breakthrough Nobody Saw
The actual birth of the electric Christmas light happened in a townhouse on East 36th Street in New York City. The year was 1882. Edward Hibberd Johnson, who was Thomas Edison’s partner and the VP of his company, decided to do something flashy. He hand-wired 80 red, white, and blue lightbulbs—the size of walnuts—and wrapped them around a rotating evergreen tree.
It was brilliant. Literally.
Johnson invited the press. He knew he needed a spectacle to convince a skeptical public that electricity wasn't going to murder them in their sleep. A reporter from the Detroit Post and Tribune was actually there and wrote that the tree was "lighted by eighty ivory-colored, egg-shaped glass lamps."
But here’s the kicker: the public didn't care.

Most people didn't have electricity. Even if they did, the cost was astronomical. You couldn't just go to a Target and buy a box of LEDs for ten bucks. You had to hire a professional wireman to hand-solder the bulbs together. It was a luxury for the ultra-wealthy, a high-tech flex that the average person couldn't dream of affording.
Why the White House Changed Everything
For a long time, the question of when were christmas lights invented is followed by the question of when they actually became popular. That didn't happen until 1895. President Grover Cleveland requested an electric light display for the White House tree.
He wanted to impress his young daughters.
Once the First Family did it, the "trend" started to trickle down, but it was still insanely expensive. To give you some perspective, a string of 24 lights in the early 1900s cost about $12. That sounds cheap, but in today’s money, adjusted for inflation, you’re looking at over $350. You could also rent them, which was a big business for a while. General Electric actually offered a rental service because they knew nobody could afford to buy the hardware outright.
The NOMA Empire and the End of Candles
By the 1920s, things started to shift. A company called NOMA (National Outfit Manufacturer's Association) formed. They were a massive conglomerate that basically cornered the market on holiday lighting. They were the ones who finally made pre-wired strings accessible.
Before NOMA, you were basically an amateur electrician if you wanted a lit tree.

Albert Sadacca is a name you should know. Legend says that in 1917, after a horrific fire in New York caused by tree candles, he suggested his family’s novelty lighting company start selling colored strands for the holidays. He was a teenager at the time. By the 1920s, he and his brothers organized NOMA, and the "modern" Christmas light industry was officially born.
The Evolution of the Bulb: From C7s to LEDs
If you grew up in the 50s, 60s, or 70s, you remember the C7 and C9 bulbs. Those big, chunky, painted glass things that got hot enough to melt plastic or burn your hand? Those were the standard for decades. They used a "series" circuit.
One goes out, they all go out.
It was a nightmare of testing every single bulb to find the "dead" one.
- Series Circuits: The old way. One break in the wire or one burnt filament killed the whole vibe.
- Parallel Circuits: The game changer. Even if one bulb dies, the rest stay lit because the electricity has multiple paths.
- Miniature Lights: In the 1970s, these tiny "incandescent" bulbs took over. They were cheaper to produce and used less energy, though they still got pretty warm.
Then came the LED.
Light Emitting Diodes (LEDs) didn't really hit the Christmas scene in a big way until the late 1990s and early 2000s. They were expensive at first. They also had a weird, flickering "cool" blue tint that people hated. But the energy savings were too big to ignore. An LED strand uses about 90% less energy than the old C7 bulbs. Plus, they last for 50,000 hours.

Safety and Technology: A Modern Perspective
We’ve come a long way from Edward Johnson’s hand-wired walnut bulbs. Modern lights are smart. You can control them with your phone. You can sync them to a Tchaikovsky remix.
But the core tech is still surprisingly similar.
We still use the basic principles of electrical conductivity that Edison and Johnson pioneered in that NYC townhouse. The main difference is the material. We moved from carbon filaments to tungsten, and eventually to the solid-state semiconductors in LEDs.
Honestly, the biggest hurdle wasn't the invention itself. It was the infrastructure. Until cities were fully gridded for electricity, Christmas lights were just a weird laboratory experiment. It took nearly 40 years for the invention to move from a "rich guy's toy" to a standard household decoration.
Actionable Holiday Lighting Tips
If you're looking to upgrade your setup based on this history, here's how to do it right:
- Check the UL Rating: Always look for the Underwriters Laboratories (UL) tag. Red tags mean for indoor/outdoor use; green tags are indoor only. This matters because outdoor insulation is built to withstand moisture and UV rays.
- Calculate Your Load: Don't daisy-chain more than three strands of traditional incandescent lights. LEDs are more forgiving, but even they have limits. Check the wattage on the box.
- Storage Matters: To prevent the "spaghetti mess" next year, wrap your lights around a piece of cardboard or a dedicated plastic reel. It prevents the tiny copper wires inside from snapping during the off-season.
- Check for Fraying: If you have vintage C7 or C9 lights, inspect the rubber coating. It gets brittle over time. If you see copper, throw them away. History is cool, but a house fire isn't.
Understanding when were christmas lights invented makes you realize how much we take for granted. We went from "I hope my house doesn't burn down tonight" to "I can change my tree color from my Apple Watch." That's a massive leap in just over a century. Keep your wires dry and your connections tight.
