The Plus T office floor lamp represents a classic approach to workplace lighting, combining refined design with high-quality materials, maximum light output, and long-lasting performance. Engineered specifically for open-plan offices and co-working spaces, it is designed to illuminate up to four workstations at once with balanced, comfortable, and highly efficient light.
At the heart of this system is the patented Open Structure Antiglare (OSA) technology. This innovative louvered LED grid uses an open structure that ensures perfectly uniform and glare-free light distribution. The design not only enhances visual comfort but also supports well-being and productivity, particularly for users working extensively at computer screens. The long luminaire head delivers consistent brightness across work surfaces while also contributing to ambient illumination, creating an ergonomic lighting environment that reduces fatigue and eye strain.
Performance is one of the key strengths of the Plus T. With advanced LED technology, the fixture provides up to 32,000 lumens of output, achieving a luminous efficacy of 125 lm/W. It directs approximately 11 percent of its light directly onto the work surface, while 89 percent is distributed indirectly into the surrounding space. This careful balance ensures both task clarity and ambient comfort. The neutral white light at 3500K, with a color rendering index above 80, provides natural and accurate color representation for workplace applications.
The fixture integrates several intelligent control features to optimize energy efficiency and adaptability. A constant light regulator automatically adjusts the brightness based on ambient light conditions, ensuring consistent levels while reducing energy consumption. A built-in motion sensor detects occupancy and switches the lamp off when workstations are not in use, with settings that can be customized for specific usage needs. The system is dimmable via an integrated pushbutton, and remote control is included for additional convenience. For collaborative spaces, the optional Swarm Connect function allows multiple fixtures to communicate, creating coordinated and responsive lighting across large office areas.
Sustainability is central to the design and production of the Plus T. Manufactured on the company’s Hamburg campus, the fixture is built with durable aluminum components and a high-quality powder-coated finish. The production process emphasizes efficient material use, local supplier collaboration, and adherence to strict social and environmental standards. Longevity, reuse of materials, and responsible sourcing are guiding principles, ensuring that the luminaire embodies both technological and ethical innovation. With an average LED life of 50,000 hours, the product is designed to provide lasting value while minimizing environmental impact.
Practical details further highlight its thoughtful engineering. The floor-mounted lamp has a total power consumption of 2x98W, with a connection cable length of 2.9 meters. It weighs 17 kilograms including packaging and is designed to integrate seamlessly into professional office environments. Rated for protection class I and operating at 220–240V, it offers robust safety and reliability.
Altogether, the Plus T floor lamp stands as a benchmark in workplace lighting, blending advanced LED performance, glare-free comfort, intelligent controls, and sustainable design. It is not only a technical solution but also an ergonomic and environmental contribution to modern office spaces.
