The PH 80 LED Portable Lamp from Louis Poulsen features a logarithmic spiral design to ensure even light distribution along its shade’s curve. The original lamp was introduced in 1925, pioneering a scientific approach to light design. This updated version, designed by Poul Henningsen, maintains the innovative approach, reflected in a diffused, symmetrical glow, with most of the light directed downward for a soft, balanced ambiance. This portable lamp can easily move from place to place without the hassle of cables, and it charges via a USB-C port.
