Up to 30,000 candles: the secrets behind Candlelight’s XXL installation in Lyon

Save

In Lyon, you’re familiar with Candlelight: these concerts bathed in a sea of light in the heart of the Presqu’île or on the city’s hills. But have you ever realized what it actually means to set up “thousands” of candles? 5, 000, 15, 000, sometimes 30,000 units depending on the venue.

If everything seems simple when the musicians take the stage, it’s because a precision operation has been underway for hours.

The setup: how the lighting comes together

It all starts with unpacking: boxes open to reveal rows of ready-to-use candles. The pace is steady, efficient, almost down to the millimeter.

Next comes the setup. Each candle finds its strategic spot: on the floor, along the aisles, or around the stage. We align, space out, and adjust the curves so the halos echo one another. It is the room’s architecture that dictates the movement.

Finally, the lighting. This is the moment when the space takes on a new dimension. Light spreads in waves, the twilight gains texture, and the space becomes naturally warm. At the Basilica of Notre-Dame de Fourvière, the stone seems to absorb this light and gently reflect it back.

To put the scale into perspective: 15, 000 candles is the equivalent of 15,000 coffee cups or tea glasses placed one by one on the floor. Double that for major events: massive logistics for a result of pure elegance.

Once the last note has faded, everything is reversed. We turn off the lights, gather everything up, and put it away. The room returns to its everyday appearance in the blink of an eye, before the ritual begins anew elsewhere the next day.

From now on, when you take your seat at Candlelight in Lyon, you’ll know: behind this suspended moment lies rigorous and generous work behind the scenes, making every evening unique.
