It happens every year right after Thanksgiving. The sun drops behind the Wasatch Range, the air turns crisp enough to see your breath, and suddenly, millions of tiny LEDs flicker to life. If you’ve ever driven past a massive, white granite building glowing like a beacon in the middle of December, you’ve seen them. Mormon temple Christmas lights aren't just a local tradition in Utah; they’ve become a global phenomenon that draws millions of people, regardless of whether they’ve ever stepped foot inside a church.
Honestly? It’s a bit of a logistical miracle.
We aren't talking about your neighbor Dave’s inflatable reindeer display. These are choreographed, high-voltage productions. They require months of planning and an army of volunteers. For most people, the Temple Square display in Salt Lake City is the crown jewel, but the tradition has spread to temples from Mesa, Arizona, to Washington D.C. It’s a weirdly specific type of holiday magic that manages to feel both incredibly corporate and deeply personal at the same time.
The Massive Scale of Temple Square
Salt Lake City is the mothership. For decades, the lights here were the undisputed heavyweight champion of religious holiday displays. But things changed recently. Due to the massive, multi-year renovation of the Salt Lake Temple—a project aimed at seismic upgrades that basically turned the center of the city into a construction zone—the light display had to scale back.
It’s different now. You can't walk the same paths.
Before the construction, you’d see roughly 800,000 lights. That’s a lot of wire. Workers usually start wrapping the trees in August. Imagine that. It’s 95 degrees outside, and you’re on a cherry picker wrapping a branch the size of a twig in tiny incandescent bulbs. They use a specific technique where they wrap every individual branch, not just drape them. It creates this skeletal, glowing effect that looks more like bioluminescence than a Christmas decoration.
The centerpiece is usually the Cedar of Lebanon. It’s a literal tree brought from the Middle East as a seedling over 75 years ago. When it’s lit, it’s breathtaking. People propose under it. Kids cry under it because they’re cold. It’s a whole scene.
Why Mesa and D.C. Are Giving SLC a Run for Its Money
While Salt Lake is dealing with scaffolding and dust, other locations have stepped up. The Mesa Arizona Temple is a heavy hitter. They don't have snow, but they have palm trees wrapped in neon blues and oranges. It’s a desert vibe that hits differently. They see nearly 400,000 visitors in a single month.
Then you have the Washington D.C. Temple in Kensington, Maryland. If you’ve ever driven the I-495 Beltway, you know the one. It looks like the Emerald City. During Christmas, they line the reflecting pool with lights and host a Festival of Lights that includes performances from international choirs. It’s a massive diplomatic event, often attended by ambassadors. It’s high-stakes decorating.

The Technical Nightmare of Millions of Bulbs
Let’s talk shop for a second. How do you keep these things running when it’s sleeting sideways?
The Church of Jesus Christ of Latter-day Saints has shifted almost entirely to LED technology over the last decade. It wasn't just about being "green," though that’s a nice perk for the PR team. It was about power draw. When you have hundreds of thousands of lights, you can literally trip a city-sized circuit breaker if you aren't careful. LEDs pull a fraction of the wattage, which allowed the displays to get even denser.
They also use "smart" controllers. These aren't just plugged into a power strip. Most of the modern Mormon temple Christmas lights are managed by digital systems that can dim or brighten specific zones to create a sense of movement.
- Custom Wiring: Much of the wiring is custom-fitted to the specific trees to hide the "guts" of the operation.
- The Life Cycle: Bulbs are tested year-round in warehouses.
- Volunteer Labor: Thousands of hours are donated by local members who see it as a form of "service."
It’s a massive investment. The church doesn't release the exact dollar amount spent on the electricity bill, but local estimates for the larger temples suggest it's in the tens of thousands of dollars for the season.
Does it actually help with SEO or "Proselytizing"?
Kinda. The church is very aware that these lights are a "front door" for the public. You’ll see young missionaries walking around with badges, ready to chat. But usually, they’re pretty chill. They know most people are just there for the Instagram photo or to keep the kids quiet for an hour.
From a "brand" perspective, it works. It humanizes a religion that many people find mysterious or insular. When you’re standing in front of a glowing Nativity scene with recorded music playing from hidden speakers, you’re not thinking about theology. You’re just looking at the pretty lights.
What Most People Get Wrong About Visiting
A lot of tourists think they can just show up and walk into the temple. Nope.
The temples themselves are closed to the general public for worship. The light displays are strictly an "outdoor" or "visitor center" experience. You don't need a ticket for the lights (usually), and you definitely don't need to be a member of the church.

One thing people often miss is the international flair. In Salt Lake, they usually have a display of creches (Nativity scenes) from all over the world. They’ve got sets made of everything from banana leaves to hand-blown glass. It’s actually one of the more culturally interesting parts of the whole experience, but people often skip it because they’re too focused on the big trees.
The Best Time to Avoid the Crushing Crowds
If you go on a Saturday night in mid-December, you will regret it. You’ll be shoulder-to-shoulder with thousands of people, many of whom are pushing strollers like they’re driving tanks.
Try a Tuesday night. Go late—around 8:30 PM. The lights usually stay on until 10:00 or 11:00 PM. The vibe is much more peaceful when the crowds thin out. You can actually hear the music and appreciate the detail in the wrapping.
The Symbolism Behind the Glow
It’s not just about looking "cool." For the Latter-day Saints, the lights represent the "Light of Christ." It’s a literal manifestation of their "Light the World" campaign. They want the temples to look like a "city on a hill."
When you look at the white marble of the Oakland Temple or the spires of the San Diego Temple against the night sky, the contrast is intentional. The lights are meant to lead your eyes upward. It’s architectural psychology 101.
Practical Tips for Your Visit
If you’re planning to hit a temple display this year, here’s the reality check you need:
1. Park Far Away.
The parking lots at the temples themselves fill up by 5:00 PM. Save yourself the headache. Find a parking garage a few blocks away or use public transit like UTA Trax in Salt Lake. Walking four blocks is better than idling in your car for 45 minutes.
2. Dress for the Arctic.
Temples are often built on hills or in open areas where the wind whips. Even if it feels "okay" at your house, standing still on a plaza for an hour is a different beast. Layers are your best friend.

3. Check the Construction Status.
This is huge. Don't drive to Salt Lake City expecting the 2015 experience. The Main Street Plaza is often the only part open during the renovation. Check the official church website for the specific temple you’re visiting to see if the lights are even happening. Some smaller temples have stopped doing large displays to save on costs or due to local zoning laws.
4. Respect the Vibe.
It’s a religious site. You don't have to be religious to be there, but maybe don't bring your loud speakers or start a protest. People are there for a bit of peace.
The Future of Temple Lights
With the rise of "immersive" light shows like Enchant or World of Illumination, the church is facing some competition. People are getting used to high-tech, paid light experiences with food trucks and beer gardens.
The Mormon temple Christmas lights offer something different: silence (mostly) and no entry fee. In a world where every holiday activity costs $40 a head, the fact that these massive displays remain free is a major reason they stay relevant. They are a throwback to a time when holiday displays were about community rather than commerce.
Whether the lights will stay this massive forever is anyone’s guess. As the church grows globally, they seem to be shifting focus toward smaller, more sustainable displays in local neighborhoods rather than just one massive "destination" show. But for now, the tradition holds strong.
Your Next Steps for a Successful Trip
Don't just wing it. If you want to see the best displays, start by checking the "Light the World" official schedule online, which usually drops in early November. This will tell you the exact "switch-on" dates for temples in your region.
If you’re heading to the Salt Lake display, download a map of the current construction bypasses. It’ll save you from hitting a dead-end fence while trying to find the Nativity. Finally, if you're visiting a warmer climate temple like Mesa or St. George, go after 9:00 PM when the heat has actually dissipated; the stone plazas hold onto the sun’s heat all day and can be surprisingly sweltering even in December.
Plan your route, grab some hot cocoa in a thermos, and get there early enough to catch the transition from dusk to dark. That’s when the magic actually happens.
