If you're traveling from California to Las Vegas, the first sign of the Strip isn't the Sphere, Strat, or High Roller wheel. For those driving after dark, it’s the "sky beam" shooting straight up from the top of the Luxor, breaking through the clouds above the elevated desert terrain that surrounds the valley. Think of it as an early greeting that says, "Welcome to Fabulous Las Vegas" long before any sign has a chance to do the same.
🔆 What is the Sky Beam?
The Luxor’s light beam is powered by 39 Xenon lamps — the same type used for spotlights. Each lamp is 7,000 watts, which together have the power of more than 42 billion candles. The beam has been a part of the Luxor since the pyramid-shaped resort opened in 1993, sticking around long after attractions like the Nile River boat ride disappeared.
🤔 How Does It Work?
While the light appears to emerge from the very tip of the pyramid’s peak, the beam’s operations occupy the top six stories of the pyramid. Computer-designed mirrors collect the light, forming what appears to be a single, focused beam that’s projected into the Vegas sky.
💡 Does Somebody Just Flip a Switch Every Night?
No. The lamps are automatic, synchronized with an atomic clock to activate at sunset and run for about eight hours. So the sky beam ceases well before sunrise (while most of us are still asleep) and no longer runs until dawn. You may have noticed — the beam isn’t quite as bright as it used to be. On average, just 18 of the 39 lamps are used each night. As a way to conserve energy and keep the carbon footprint in check, the amount of lights running at any given time have been reduced by 25 percent.
🧰 Maintenance Check
It takes about 1.008 million watts to power the beam each night. Over the course of a year, the 18 lamps run for a combined 52,560 hours. Each one has a lifespan of around 2,000 hours, needing to be replaced every 250 days or so.
🦇 Wild, Wild Life
The powerful light beam tends to attract moths, bats, and owls. Think of it as the circle of life, playing out for all to see on the Las Vegas Strip. You’ll notice the bats clearly from the Skyfall Lounge at the top of the W hotel (formerly the Delano), which has a clear, neighboring, unobstructed view of the Luxor beam.
🫥 Will the Beam Ever Truly Go Away?
Probably not. MGM Resorts once surveyed visitors to see if they’d miss it. Most said to keep it.
