Louis Poulsen LP Slim Round 440 suspension lamp

Louis Poulsen LP Slim Round 440 is a LED suspension lamp with a slim profile and refined aesthetic, designed to ensure a consistent visual identity across complex architectural environments with diverse functions. The circular body, with a diameter of 438 mm and a contained height of 155 mm, incorporates an aluminium reflector and a high-efficiency acrylic diffuser, with a slight external and internal curvature that reduces light contrast and gives the form an elegant and distinctive character.

The LP Slim Round 440 is the ideal choice for offices, open spaces, reception areas and meeting rooms — wherever aesthetics and formal simplicity are fundamental requirements. The integrated 25 W LED source delivers a luminous flux of 2404 lm at a colour temperature of 3000 K (warm white) and a CRI 90 colour rendering index, ensuring accurate and natural colour perception. Light emission is diffused primarily downwards, with an indirect component that contributes to a uniform, glare-free atmosphere. Dimming is managed via a DALI system, enabling precise control and seamless integration with building automation infrastructure. The average lifespan of the light source is 100,000 hours, ensuring long-term reliability. The suspension cable is adjustable up to a maximum of 5,000 mm, and the canopy with integrated driver is included. The protection rating is IP20, suitable for indoor use. The lamp is compatible with the main international voltage standards (EU, AUD, USA, UK, JAP) and is available in black, dark aluminium raw and white finishes. Versions with a 4000 K light temperature and those with the Dynamic White function are available on request.
