Louis Poulsen VL45 Radiohus battery lamp

Louis Poulsen VL45 Radiohus battery lamp is a portable lamp inspired by Vilhelm Lauritzen's iconic Radiohus VL 45 pendant, originally designed in the 1940s for Radiohuset, the Danish broadcasting house. Crafted from blown opaline glass with an untreated brushed brass structure, burnished brass detailing and a genuine leather strap, this lamp brings its timeless light to any setting — indoors or outdoors — thanks to its IP44 degree of protection. The energy-saving integrated LED source delivers warm white light at 2700 K with a luminous output of 270 lm at full power.

Originally known as the office lamp, the VL45 has established itself as an enduring icon of Scandinavian design, adapting with ease to both modern and classic interiors. It is an ideal choice for the living room, the bedroom or an outdoor setting, creating an atmosphere of refined, timeless light. The continuous 4-level dimming system — 5%, 20%, 45% and 100% — allows precise control over light intensity to suit every moment. Charging is handled via a USB-C to USB-C cable, compatible with standard USB adapters (min. 1.5A), for effortless and versatile use. Battery life ranges from 5 hours at full power to 38 hours at the 5% minimum level, with 7 hours at 45% and 13 hours at 25%. The lamp is available in several opaline glass finishes — glossy pale pink, glossy pale yellow or glossy white opal — with slight variations in colour intensity possible between individual pieces. With a total height of 260 mm and an upper diameter of 120 mm, the VL45 Radiohus is a piece of design history that not only illuminates, but enriches every space with its timeless elegance.
