Pholc Romb Mini battery table lamp

Romb Mini is the battery-powered table lamp by Pholc, designed by Stockholm-based designers Broberg & Ridderstråle. Crafted in aluminium, it features a distinctive geometric silhouette inspired by two stacked corrugated cardboard shapes: the rippled surface and compressed form convey an almost tactile lightness, making it a refined and intriguing design object. Equipped with a G4 lamp holder and an integrated 3 W LED bulb included, it delivers warm light at 2700 K and carries an IP44 protection rating, suitable for environments with occasional moisture. Its compact dimensions — 110 mm wide and 192 mm tall — make it ideal for any surface.

Thanks to the built-in rechargeable 18650 battery (3.7 V / 3350 mAh), Romb Mini requires no fixed electrical connection, offering total freedom of placement. It recharges via the USB-C cable included (5 V / 1 A input) in approximately 5 hours; a power adapter is not included. The lamp is dimmable across three levels: at 100% it emits 280 lumens with 3 hours of battery life, at 40% it delivers 108 lumens for up to 12 hours, and at 10% it provides 28 lumens for up to 40 hours of use. The 40% setting is recommended for a soft, ambient light with extended autonomy. A universal input voltage of 100–240 V and insulation class III complete a safe and versatile technical profile. Romb Mini is a natural fit for the living room, the bedroom, or any space that calls for Scandinavian design with effortless practicality.
