Louis
Louis urban luminaire has a slender linear character with elegant symmetrical forms. Inspired by Louis Kahn’s reflections on space and light, and on the order dictated by geometry, which is ultimately responsible for form. An element that carefully manipulates light to trace, in suspension, free compositions in green environments and pedestrian spaces.






A new urban landscape
Louis urban luminaire harmonises the urban space as a catenary in linear repetition compositions or in free-standing arrangements on the project layout. Protected from the unfavourable climate by a screen, it has two lighting alternatives for symmetrical light control, high energy efficiency and zero light pollution.
- Luminaire made of extruded aluminium 6063 T5 and anodised injection-moulded aluminium AC-47100 with powder-coated finish-
- Tempered optical glass diffuser with silicone sealing gaskets.
- A2 stainless steel hardware and metal cable gland.

Service life
TM21 L90 (10k) > 100,000 h
All our products support remote regulation, both individually and in groups, through the most standardised control systems, significantly reducing energy consumption and eliminating light pollution. We adapt our products to safeguard biodiversity and respect circadian rhythms, eliminating harmful wavelengths.
Our luminaires comply with the American IESNA LM80 and TM21 standards.
Controls
1-10V / 0-10V
Analog one-way regulation protocol that, through a signal between 1 or 0 and 10 V, allows remote linear control of the luminous flux between 10% or 0% and 100%. The standard programming is as follows: Vi ≥ 8V – 100%; Vi ≤ 1V – 10%.
DALI
Two-way digital communication protocol (Digital Addressable Lighting Interface) that allows grouping, regulating, and turning off the luminaire, using an 8-bit resolution with 254 regulation steps and receiving information about its status for maintenance.
Programmes
Automatic programming
Individual, self-managed programming in the product and bi-directional. It is configured prior to installation. It is useful in projects that require a single pattern throughout the product’s life. It incorporates automatic regulation steps with geolocation and real nighttime cycles.
Example: 100% from 21:00 to 22:00; 70% from 22:00 to 01:00; 50% from 01:00 to 05:00; 70% from 05:00 to 08:00.
Automatic control panel programming
Individual, self-managed programming in the control panel and one-way. It is configured prior to installation. It can coexist with other analog voltage reduction technologies, such as phase-cut. It is useful in projects that need different patterns throughout the year or the product’s life.
Example: Summer 100% from 21:00 to 22:00; 70% from 22:00 to 01:00; 50% from 01:00 to 05:00; Winter 100% from 16:00 to 22:00; 70% from 22:00 to 01:00; 50% from 01:00 to 08:00.
Command line programming
Group regulation, in the control panel and one-way. It requires the installation of an additional control electrical line besides the power line (2×2.5mm2). It is useful in projects that need simplified regulation.
Lighting Flow dimmer programming
Group regulation, in the control panel and one-way. It requires the installation of a stabilizer/voltage regulator in the control panel and product configuration to interpret the correlation between line voltage and power. It is useful in projects that need a simplified system with existing regulators.
Example: Vi ≥ 230V – 100%; Vi ≤ 185V – 60%
Functionalities
Constant Luminous Management (CLM)
Optional function parallel to the programming that maintains the project illumination levels constant throughout the installation’s life, increasing the luminaire’s power proportionally to the LED depreciation. Our standard programming is 0h 80%; 60,000h 100%.
Temperature control
Optional automatic protection to safeguard the integrity of the lighting components. It monitors the maximum temperature, activating a flow reduction to recover an acceptable value.
Surge protection
Protector against voltage spikes caused by thunderstorms. Sized for a maximum discharge current of 10kA.
- Clean using pH neutral, alcohol-free, nonabrasive cleaning products.
- The optical glass can be cleaned with non-abrasive cleaning products.

Applications
Catenary lighting allows the layout of the light points to be separate from the rigidity of the program, creating spaces for people and nature. The luminaire, which can be installed on catenary cable (Ø 4-6 mm), offers different orientations of the light source to adapt the luminous flux to the needs of the space.
Installation
The accessory is attached to the luminaire. Hang the assembly on the catenary cable.
Steel cable which can be used: Ø 4-6 mm.
Installation instructions and hardware included.
Cable for catenary not included.
