{"product_id":"ph-3-2","title":"PH 3½-2½","description":"\u003cp data-start=\"216\" data-end=\"717\"\u003eDesigned in 1928 by Poul Henningsen for Louis Poulsen, the PH 3½–2½ is part of the development of the three-shade system launched two years earlier. Developed according to a logarithmic spiral, this geometric principle allows for precise light distribution and optimal glare control. Henningsen thus pursued his goal of adapting electric lighting to domestic visual needs, combining photometric efficiency with user comfort.\u003c\/p\u003e\n\u003cp data-start=\"719\" data-end=\"1128\"\u003eThe shades are made of three-layer mouth-blown opal glass, polished on the outside and sandblasted on the inside to diffuse a soft, uniform light. The assembly rests on a balanced metal structure, faithful to the original design. Through its formal rigor and optical mastery, the PH 3½–2½ embodies the rational research conducted by Henningsen on the quality and direction of light.\u003c\/p\u003e\n\u003ch3 data-start=\"540\" data-end=\"557\"\u003eColor\u003c\/h3\u003e\n\u003cp data-start=\"558\" data-end=\"654\"\u003eShade: opal white\u003cbr data-start=\"583\" data-end=\"586\"\u003eStructure: black\u003cbr data-start=\"637\" data-end=\"640\"\u003eCable: black\u003c\/p\u003e\n\u003ch3 data-start=\"661\" data-end=\"680\"\u003eMaterials\u003c\/h3\u003e\n\u003cp data-start=\"681\" data-end=\"810\"\u003eShade: mouth-blown opal glass, three-layer\u003cbr data-start=\"729\" data-end=\"732\"\u003eStructure: drawn brass, brass and polished chrome finish\u003cbr data-start=\"788\" data-end=\"791\"\u003eCable: plastic\u003c\/p\u003e\n\u003ch3 data-start=\"817\" data-end=\"866\"\u003eLight source and electrical data\u003c\/h3\u003e\n\u003cp data-start=\"867\" data-end=\"1017\"\u003eSource: 1 × E14, max. 60 W (not included)\u003cbr data-start=\"908\" data-end=\"911\"\u003eVoltage: 220–240 V\u003cbr data-start=\"930\" data-end=\"933\"\u003eIngress protection: IP20\u003cbr data-start=\"960\" data-end=\"963\"\u003eElectrical class: II\u003cbr data-start=\"985\" data-end=\"988\"\u003eSwitch: on cable\u003c\/p\u003e\n\u003cp data-start=\"626\" data-end=\"666\"\u003eManufacturer and product reference\u003cbr\u003eLouis Poulsen, 5744166179\u003c\/p\u003e","brand":"Louis Poulsen","offers":[{"title":"Default Title","offer_id":55948990939468,"sku":null,"price":1610.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/0546\/5420\/files\/PH_3_-2_-eclairage-francais_2.webp?v=1763231657","url":"https:\/\/eclairagefrancais.fr\/en\/products\/ph-3-2","provider":"ÉCLAIRAGE FRANÇAIS","version":"1.0","type":"link"}
