What Time Does the Eiffel Tower Light Up?

The golden lighting: Paris’s evening dress

Each evening, as the sun drops below the horizon, the Eiffel Tower puts on its famous golden gown. No attendant flips a switch: the system uses twilight sensors that detect falling light levels and trigger the display automatically.

Full switch-on takes less than ten minutes. First the pillars, then the structure lights progressively to the top. This free spectacle has repeated every night since 1985.

Key figures on the lighting

• 336 high-pressure sodium lamps make up the golden wash
• Each lamp is rated at about 1 kW
• The last full renewal of the system was in 2019
• Bulbs are typically replaced every four years

The distinctive gold tone is deliberate: it echoes the original “brown-red” paint chosen by Gustave Eiffel while giving the monument warmth and elegance at night.

The sparkle: 20,000 flashes of theatre

The moment everyone waits for comes on the hour. For exactly five minutes the tower glitters as if thousands of cameras were flashing at once.

The effect comes from 20,000 6 W bulbs strobing in very rapid sequence. It really does resemble press flashes—and that is no accident: designer Pierre Bideau drew inspiration from that phenomenon at big public events.

Typical sparkle times by season

The last sparkle: a special moment

At midnight (or 1:00 a.m. in summer), something unique happens. The golden lighting and beacon go out, leaving only the sparkle for five minutes. The tower looks like a constellation before going completely dark. Many photographers call it the best moment of the night.

The summit beacon: 80 km of range

At the top, a lighthouse-style beam sweeps Paris all night. Four marine-type projectors on each face switch in sequence, creating the illusion of a single rotating beam.

The modern beacon (since 1999) nods to 1889: Gustave Eiffel already fitted his tower with a lighthouse for the World’s Fair. In clear weather the beam can be seen from up to 80 km away—theoretically as far as Chartres on a perfect night.

What exact time does it light up?

The precise switch-on changes every day because it follows sunset. The section below gives approximate ranges by month—always cross-check an almanac for your date.

Best places to watch the illuminations

Where should you stand for the full effect? After fifteen years shooting Paris at night, these are the stand-outs:

1. Trocadéro — the classic you cannot skip

Place du Trocadéro offers the most famous head-on view of the lit tower. The fountains in the gardens add reflections. Downside: crowds and street vendors in the evening.

2. Pont d’Iéna — close and dramatic

This bridge links Trocadéro to the Champ de Mars and gives a powerful low-angle view. Close enough to hear visitors on the tower—ideal for portrait-format photos.

3. Champ de Mars lawns — the local secret

On the École militaire side, the grass gives you distance and fewer tourists. Parisians picnic here to watch the sparkle—relaxed, room to sit.

4. Pont de Bir-Hakeim — the cinematic angle

Made famous by Inception: the tower beyond the metro viaduct pillars. Quieter many evenings.

5. Tour Montparnasse — the aerial view

The rooftop terrace (paid entry, roughly €18) shows the Eiffel Tower lighting up inside the wider Paris panorama—one of the few places to see the sparkle in 360° context.

Visiting the tower at night: a different experience

Watching from outside is free and spectacular. Going up at night flips the perspective: Paris’s own lights spread at your feet.

Ticketing usually runs until 22:45 for last ascent (later in high season). Evening slots around 20:00–22:00 are most sought-after because you can catch sunset, then the city after dark.

Practical tip

In summer, a slot around 21:00 lets you ascend in daylight, watch sunset from the top, then see Paris switch on below. The first sparkle from inside the ironwork feels strange—you are literally inside the show.

Can you photograph the Eiffel Tower at night?

A frequent question. In short:

• Personal use: no restriction—shoot, film, post on social media.
• Commercial use: the night lighting is a copyrighted work (Pierre Bideau’s design). SETE permission is required for commercial use—ads, print sales, stock, etc.

For holiday photos on Instagram or Facebook, normal sharing is fine; only commercial exploitation needs formal steps.
