Louis Poulsen LP Slim Round 680 suspension lamp

Louis Poulsen LP Slim Round 680 is a LED suspension lamp with a slim profile and refined aesthetic, designed to provide a homogeneous visual identity across buildings with varied environments and functions. The body, with a diameter of 679 mm and a height of just 155 mm, features a subtle external and internal curvature that reduces visual contrast and integrates a high-efficiency acrylic diffuser. The aluminium reflector and opal acrylic diffuser deliver a diffused light emission directed primarily downwards, with an indirect lighting component for a result that is visually comfortable and technically optimised.

Thanks to its essential design and availability in three finishes — black, dark aluminium raw, and white — the LP Slim Round 680 integrates seamlessly into professional and representative settings. It is the ideal choice for the office, open-plan spaces, reception areas, and meeting rooms, wherever aesthetics and formal simplicity are paramount. The integrated 53 W LED source delivers a luminous flux of 5861 lm at a colour temperature of 3000 K (warm white) and a CRI 90 colour rendering index, ensuring faithful colour reproduction and a welcoming atmosphere. Compatibility with the DALI dimming system allows precise control of light levels, while the declared average lifespan of 100,000 hours guarantees long-term reliability. The canopy is included with an integrated driver, and the suspension cable reaches a maximum length of 5000 mm. The lamp is compatible with EU, AUD, USA, UK, and JAP electrical networks, with IP20 protection rating and insulation class I. Versions with a 4000 K light temperature and those with the Dynamic White function are available on request.
