SERPENT-PLUS: Flexibility of Form and LED Performance in a Single System – Design Interiors Without Limits

In the world of modern architecture and interior design, where every detail matters and light plays a crucial role in shaping the atmosphere of a space, linear LED lighting has become an inseparable element of the most sophisticated projects. From elegant corporate offices and prestigious shopping centres to exclusive hotels and restaurants – wherever perfection of execution and reliability are paramount, architects and designers reach for solutions that combine the highest quality with functionality and aesthetics.

SERPENT-PLUS is the answer to these growing expectations – a new generation of linear LED luminaires by KLUŚ, created from a deep understanding of the needs of contemporary space creators. This article is a comprehensive guide to the innovations that make SERPENT-PLUS more than just another lighting fixture. It is a tool that allows architects to realise their most ambitious lighting visions, gives installers the confidence of fast and error-free installation, and guarantees investors long-term satisfaction with performance and energy efficiency.

The SERPENT-PLUS system offers two main installation options. Suspended luminaires are supplied as a complete set with suspension wires and a wide range of accessories to support installation, including dedicated mounting kits for solid ceilings and plasterboard ceilings. Ceiling canopies (BOX-M 70 and Fi-80) are also available in three colour variants – silver, black, and white.

Surface-mounted luminaires are available exclusively in a downlight version and are fixed using special brackets included in the set, with ZM connectors providing stabilisation during joining. A key advantage of the system is the compatibility of both mounting variants – they can be combined, allowing for compositions where suspended segments seamlessly transition into surface-mounted sections.

Within the SERPENT-PLUS luminaire range, users can choose from three types of optics: with an opal cover, with a microprismatic cover, and with a DOT-45 lens, offered with 20° and 48° reflectors, where the actual beam angle varies depending on the colour of the cover – the white cover provides a beam angle of 36°/51°, the black 27°/52°. Available housing finish colour variants include matt white, RAL9010 lacquered, black anodised, and silver anodised. On request, luminaires can be produced in any non-standard colour, including the modern premium NCS colour palette, such as: caramel (NCS S3030-Y60R), sand (NCS S2010-Y30R), pastel blue (NCS S2010-B), and light sage (NCS S2010-G50Y), enabling perfect matching to the interior design.

Thanks to its modular construction and matrix of variants, it is easy to combine SERPENT-PLUS elements into extensive systems, while maintaining aesthetic consistency and design flexibility. This wide range of shapes, optics, and finishes makes SERPENT-PLUS a comprehensive solution, meeting the needs of both modern offices and galleries, as well as private interiors requiring an individual approach to lighting.

The light source in SERPENT-PLUS luminaires is high-efficiency, constant-current LED modules powered by standard mains voltage 220–240 V/AC. In straight sections, linear tape modules are used, providing uniform distribution and high luminous efficacy, maintaining consistent light colour and minimal energy losses thanks to matched power supplies. In luminaires with DOT-45 optics, dedicated, specially adapted LED modules are used, which are carefully shaped and radially matched to the curvature of the 20° or 48° reflector, ensuring precise beam angle control and a uniform lighting effect on the curved sections of SERPENT-PLUS.

Thanks to its modular design, the system enables both striking downlighting and subtle uplighting, while maintaining a constant colour temperature (3000 K or 4000 K, CRI ≥ 90) and luminous efficacy of up to 135 lm/W from the finished luminaire.

Modern lighting requirements combine energy efficiency with user comfort and compliance with stringent building standards. SERPENT-PLUS not only achieves high luminous efficacy – up to 135 lm/W – but, thanks to three optics options, precisely controls glare in various spaces. Versions with the DOT-45 20° lens (UGR <10) are ideal where maximum glare reduction is required, such as laboratories or operating theatres. Configurations with the DOT-45 48° lens (UGR <13) provide visual comfort in conference rooms and relaxation zones, while solutions with a microprismatic cover (UGR <19) are perfect for open-plan offices and workspaces in accordance with the PN-EN 12464-1 standard. As a result, SERPENT-PLUS combines energy savings with a real reduction in eye fatigue and increased work efficiency.

In summary, each of the presented solutions allows for precise adjustment of the control method and type of light to the character of the space, while simplifying installation and subsequent operation. The use of constant-current modules and flexible control modes makes SERPENT-PLUS perfectly suited to modern projects requiring both high efficiency and ease of use.
