Novella by Sylvania: A new range of ultra-resistant and high-performance portholes suitable for both indoor and outdoor applications

A light fixture designed to meet the constraints of the building envelope

Lighting for circulation areas and surrounding spaces imposes different requirements depending on the use. Indoors, the objective remains the visual comfort and continuous lighting. Outdoors, the constraints relate more to the weather resistanceto vandalism and filth.

The Novella range is based on this dual approach. The portholes are designed for a surface mountingwith an envelope adapted to exposed environments. Their protection rating IP66K guarantees complete dustproofing and protection against powerful water jets. The index IK10 demonstrates high resistance to mechanical shocks, often required in collective housing or parking lots.

In practice, these characteristics meet the common requirements of project managers on structures subject to frequent deterioration, particularly in social housing or public facilities.

Photometric performance and energy efficiency

Two formats are offered, with different levels of flow and efficiency:

• 220 mm diameter: adjustable flow of 720 to 1550 lumens, effectiveness up to 138 lm / W
• 300 mm diameter: flow rate up to 2800 lumens, effectiveness up to 147 lm / W

The color rendering index (CRI > 80) allows for lighting adapted to everyday uses, particularly in interior circulation areas. The color temperature selection (3000 K or 4000 K) at the time of installation offers flexibility to adapt to the desired atmospheres.

In a logic of thermal and energy performance of the buildingThese levels of efficiency help to limit consumption, in line with the requirements of environmental regulations, in particular the RE2020 for new buildings.

Implementation and piloting options

The range includes several configurations to facilitate implementation and operation:

• branch connector for simplified wiring
• versions multi-power with adjustable flux via switch
• compatibility DALI for centralized management
• variations with microwave (MW) presence detector

These functions allow lighting to be adapted to the actual use of the spaces. For example, the corridor function automatically reduces the light output when the space is unoccupied, thus limiting energy consumption.

An additional sensor kit can be added to fine-tune the settings, particularly by integrating the natural light in lighting management.

In a commercial or multi-family residential project, these systems are generally configured by a fluid engineering firm, in line with the site's operational requirements.

Robustness and durability in operation

The design incorporates elements aimed at extending the lifespan of the light fixture:

• vandal-resistant screws
• option to add a protective cap
• advertised lifespan of 100 000 hours
• warranty 5 years

These features meet the expectations of wealth managers, for whom the maintenance constitutes a significant cost item.

However, one operational limitation should be noted: actual performance will depend heavily on installation and maintenance conditions. Dirt buildup or improper installation can degrade photometric performance over time.

Practical applications in projects

Novella portholes can be used in several configurations:

• building lobbies and vertical circulation
• technical corridors or service areas
• covered and outdoor parking
• facades and secondary access

On an energy renovation site, for example, replacing old light fixtures with LED bulkhead lights with motion detection makes it possible to significantly reduce consumption while improving user safety.

These solutions are part of a comprehensive approach to equipment modernization, led by the project owner and the electricity companies.

A technical solution for mixed uses

With the Novella range, Sylvania offers a luminaire adapted to constrained environments, combining mechanical resistance, installation flexibility et energy optimizationThe advantage of this solution lies in its versatility, provided it is integrated into a coherent overall design of the lighting system and its operation.
