Out of darkness comes
benevolent light.

Extending social ties beyond the sunset, while minimizing environmental and energy impacts – that’s the philosophy behind Rohl®.

Make
the night
the best
part
of your day!

With the cut-off you didn’t play
your last card…

2/3 of French lighting is made up of energy-guzzling discharge sources. This gives rise to mixed networks, often leaving total blackout as the only alternative.

Switching off has no effet on the fixed component (≈35% of the bill excluding VAT). In this context, the bills reduction rarely exceeds 35%. Switching to LEDs will have a real leverage effect, while ensuring the long-term future of the installation.

Because our life rhythms are different.

When biodiversity cries out for darkness, we look for a night.

Artificial lighting fragments habitats, especially in high-strakes areas such as dark infrastructure. If turning off is a solution, choosing the right lighting can reduce the pressure on the living world.

68% of the lighting fleet often illuminates the sky. Luminous halos cover our cities and harm endemic species.

LEDs luminaires allow you to perfectly target the area to be illuminated without illuminating the sky!

Do we consider fairness between
night & day?

Nearly 16% of the population works night shifts, and while this figure remains stable among men, it jumped by 69% among women between 1999 and 2005. This represents 4.5 million people in France, so how should we view them?(1)

Public lighting plays an active role in the dynamism of a terretory, both for social and professional activities. More than 15% of the French population works at night. What about fairness?

Darkness where even poor lighting can lead to a strong feeling of insecurity, an archaic fear that can lead to reduced travel and therefore social life.

Lightning must become agile & dynamic…

A night, like a scenario, has several temporalities and integrates different scenes.

Between energy, environmental and social issues, your lighting needs to become agile and dynamic, so that it responds accurately to the context of the moment and the place.

What if the solution was to be able to easily define and adjust these scenarios according to needs?

Enter
the era
of dynamic
night…

But concretely what is dynamic night?

The dynamic night is our vision : to offer clear solutions that allow you to simply implement a lighting plan that meets the mobility challenges of tomorrow, while reconciling energy, environmental and social issues.

Our towns and villages, just like our nights, are multi-faceted, and no single response can be relevant to the needs of the places, their inhabitants and their uses…

Guided by nocturnal behaviors, the scenarios we propose vary according to the location, the emphasizing one of the three axes of sustainable development:
