Applications

Office and Administrative Areas

Uniform general lighting for desks and conference rooms. The homogeneous illumination reduces glare and shadows while promoting concentration and well-being.

Production and Manufacturing

Reliable illumination of work surfaces and assembly stations. High CRI and stable color temperature ensure precise color evaluation and safe workflows.

Retail and Sales Areas

Attractive product illumination without light shifts. The four available sizes enable flexible adaptation to different room geometries.

Laboratories and Cleanrooms

IP20 protection and hygienic approval enable use in sensitive environments. Maintenance-free LED modules minimize contamination risks.

Storage and Logistics Areas

Energy-efficient full-area illumination of large spaces. Four diameters allow optimal adaptation to ceiling height and storage area dimensions.

Product Benefits in Detail

Four Sizes for Flexible Project Adaptation

The K-Circum is available in four diameters: 450 mm (25 W, 4,364–4,589 lm), 650 mm (50 W, 8,728–9,177 lm), 950 mm (84 W, 14,546–15,296 lm), and 1,200 mm (available on request). This range enables precise adaptation to room size and lighting requirements without over- or under-lighting.

Highly Efficient LED Technology with Long Service Life

The non-replaceable LED module operates at power ratings between 25 and 92 W and achieves a service life of 50,000 hours (L70/B20). This corresponds to more than 5 years of maintenance-free operation in continuous use and significantly reduces lifecycle costs.

Perfect Complement to the K-Ring Luminaire

The K-Circum was designed as a full-circle surface-mounted luminaire and harmonizes perfectly with the K-Ring luminaire family. Both luminaire types use identical color temperatures and CRI values, enabling combined installations for advanced lighting concepts.

Installation Flexibility and Control Options

Available as a surface-mounted luminaire or pendant luminaire (standard), and upon request as a recessed luminaire. ON/OFF control is standard; DALI control is optionally available. This allows the K-Circum to integrate into various building automation systems.

Typical Applications

Large-area illumination of a production hall using 950 mm diameter luminaires in 4,000 K for optimal color control during assembly work. At the same time, 450 mm luminaires in 3,000 K can be used above desks to provide comfortable ambient lighting. Alternatively, a warehouse retrofit with mixed luminaire sizes can reduce energy consumption compared to older halogen lighting while maintaining or improving illumination quality.
