The PH 1/1 LED Portable Lamp from Louis Poulsen is a portable, practical design pairing a compact metal body with an expressive three-shade bloom above. Designed by Poul Henningsen, the iconic multi-shade system derives from a logarithmic spiral to deliver soft, even illumination. The mouth-blown glass shades offer an elegant counterpoint to the smooth metal stem, reducing glare and accentuating its surroundings with gentle shadows. Fine knurled details add a retro contrast to the functionality of the step dimmer and USB-C charging, offering up to five hours of untethered operation and a welcoming atmosphere wherever it is placed.
