Louis Poulsen PH 1/1 Portable wireless lamp

In 2026 Louis Poulsen presents the new PH 1/1 Portable, a wireless and even smaller version of the classic and historic table lamp. Together with the PH Centenary Chandeliers, it represents the first official reissue of the 1:1 diffuser set, the smallest whole number that uses a complete set of diffusers of the same scale. The PH 1/1 is a contemporary interpretation of the historic system, created with the utmost respect for the original concept and with a pleasant aesthetic factor.

PH 1/1 Portable, battery-powered lamp rechargeable via an included USB cable, with dimming memory function. Shades made of mouth-blown white opal glass, lamp body in metallized brass or high-gloss chrome.
