Every December, the streets, houses, and shopping malls are filled with twinkling lights, LED string lights, and illuminated trees that look like they're straight out of a fairy tale.
But have you ever stopped to think about where this almost universal desire to fill everything with light at the end of the year comes from?
The answer isn't in shop windows or Black Friday ads: it lies in centuries of fear of the dark, a search for hope, and immense human ingenuity.
According to a 2025 report by Research and Markets, the global Christmas lighting market is expected to exceed US$20.2 billion this year alone—a figure that proves Brazilians are not alone in this passion.

What is the true, forgotten origin of Christmas lights?
It all began in 17th-century Germany, when Lutheran families placed lit candles in pine trees inside their homes.
The flame represented Jesus as "the light of the world" and also recalled the ancient winter solstice bonfires of the Germanic and Nordic peoples—pagan rituals to ward off the darkness and "call the sun back.".
In other words, Christianity took a pre-Christian tradition, gave it a new meaning, and spread it throughout Europe.
However, setting fire inside a house wasn't exactly safe.

Accounts from the time tell of trees turning into torches in a matter of minutes, and even Martin Luther, according to legend, was inspired by the stars shining between the branches on a winter night and decided to recreate the scene with candles.
Even though it's a legend, it shows how humankind has always needed symbolic light during the darkest months of the year.
Therefore, before becoming a "shopping mall thing," Christmas lighting was an act of courage and faith: overcoming the fear of winter with controlled fire.
How did dangerous candles become safe Christmas lights?
The big turning point came in 1882, when Edward H. Johnson, vice president of Thomas Edison's company, installed the world's first electric Christmas tree in New York.
He hand-wrapped 80 red, white, and blue lights around a rotating Christmas tree—a luxury that cost the equivalent of a luxury car today.
In this sense, newspapers of the time called it a "scientific marvel," but the general public only gained access to it 40 years later, when prices fell.
In Brazil, electric lights arrived on Christmas trees around the 1930s, first in the homes of the elite in São Paulo and Rio de Janeiro.
The telephone company was still advertising in the newspapers: "Light up your Christmas with electricity — more beautiful and safer than candles!"“
Starting in the 1950s, "rice lamps" (those colorful little balls) invaded middle-class homes, and in the 1990s came the craze for Chinese LED light strips.
Today, a single LED strip uses 90% less energy than old lamps — an evolution that allows entire cities to light up without turning off the rest of the country.
Finally, have you ever stopped to think about how much risk our grandparents took just to have a beautiful Christmas?
Why have Christmas lights conquered the entire world (including countries that don't even celebrate Christmas)?
Because light in the darkness is a universal language.
In Japan, where less than 11% of the population is Christian, the winter "illuminations" attract millions of tourists and generate billions of yen every year.
In Colombia, the lights of Medellín have become an Intangible Cultural Heritage of Humanity.
In short, even in Dubai there are 30-meter-tall Christmas trees made entirely of lights.
In Brazil, we mix everything: Christmas lights with São João lights, twinkling lights made from recycled plastic bottles in the Northeast, projectors of Santa Claus dancing forró.
This capacity for adaptation explains the survival of tradition: it doesn't need to be "Christian" to make sense; it just needs to be human.
Furthermore, science helps: psychology studies show that colored lights increase the release of dopamine and serotonin, especially in latitudes where the day only has 6 hours of sunlight.
In other words, our brains literally need that extra light in December.
Christmas lights are like a collective hug that humanity gives itself every year-end — a perfect analogy for when the world seems to be falling apart.
What are two original Brazilian examples that almost nobody knows about?
The Christmas Tree Made of PET Bottles from Rolândia (Paraná)
Since 2008, the small town of Rolândia, in northern Paraná, has been assembling the largest ecological Christmas tree in Brazil using more than 40,000 PET bottles collected by the local population.
In 2024, the 32-meter tree was illuminated with 100% LED lighting powered by solar panels installed in the park itself.
In this sense, the project involves schools, waste pickers, and local businesses, proving that tradition and sustainability can go hand in hand.
The Floating Lights of the Potengi River in Natal (RN)
Every November 30th, hundreds of barges illuminated with LEDs travel down the Potengi River carrying images of saints and the baby Jesus.
The tradition began in the 1980s with fishermen decorating their boats to give thanks for a bountiful catch.
Today it has become the biggest aquatic Christmas show in Brazil, with more than 400,000 people on the shore — and zero energy expenditure for the city, since each boat has its own generator or solar panel.
| Evolution of Christmas Lights in Brazil | Period | Main feature | Curiosity |
|---|---|---|---|
| tallow candles | 1900–1930 | Only in rich people's homes | Many fires reported |
| Imported "rice" lamps | 1950–1980 | First popular craze | They burned quickly and got very hot. |
| Chinese LED hose | 1995–2010 | Everything got cheaper. | 25 de Março Street has become the "capital of flashing lights"“ |
| Solar-powered LED projectors | 2015–present | Sustainable and technological | Cities like Gramado and Petrópolis are leading the way. |
How can we keep this tradition alive without destroying the planet or increasing our electricity bill?
The answer lies in three simple and powerful attitudes:
First, replace everything with LEDs — a 10-meter strip of LEDs consumes the same amount of energy as a regular 60W light bulb.
Secondly, use timers or motion sensors: 6 hours a day is enough to charm the neighborhood.
Third, invest in solar energy: small panels cost less than R$ 350 and pay for the investment in two Christmases.
Furthermore, community-based projects for recycling old Christmas lights are growing in cities like Curitiba, São Paulo, and Recife.
The result? Less electronic waste and more money in your pocket in January.
Because tradition only survives when we update the way we do things, without losing the reason for doing them.
