The first lights using the system were designed for an exhibition in Paris. His work with Louis Poulsen continued until his death in 1967. Throughout his life, PH sought to create glare-free lighting; aiming to direct light where it was most needed, and creating soft shadows while using incandescent bulbs as a light source. The 3½-2½ Floor light is a member of the three-shade family and is one of 19 versions available today. Approximately one thousand different models have been produced over the years and consisted of table, floor and wall lamps, as well as a number of different chandeliers, which were very popular in the 30s for lighting private homes with high ceilings. There were countless combination options. The lights were available in different colors, as well as a range of sizes. The first shades were made of metal with a painted undersurface, such as white, gold or silver depending on whether diffuse, warm or cold light was desired. Glass was later introduced for the three-shade system. In addition to the downward-directed light, glass lamps illuminated the room. PH was the first person to pursue a scientific approach to light and use the logarithmic spiral as a basis. By using a design based on the logarithmic spiral he achieved even distribution of light over the entire curve of the shade. This even light distribution, together with the diffuse reflection through the glass, made it possible to control glare and shadow. Each shade reduces the amount of light equally, due to their distance from the light source. The PH light model numbers refer to the shade size. Each top shade had a corresponding set of middle and lower shades. In the pure models, such as the 2\/2, the top shade has a size of about 20 cm, with corresponding lower shades. PH 3½-2½ Floor consists of an approximately 35 cm top shade with lower shades. These hybrid models were introduced due to the desire to hang pendants at lower heights. The system was also used for floor, table and wall lamps. PH 3½-2½ Floor in its current form was introduced in 2002.\u003c\/p\u003e","brand":"Louis Poulsen","offers":[{"title":"Chrome","offer_id":37858792702142,"sku":"5744901376","price":3395.0,"currency_code":"CAD","in_stock":true},{"title":"Black Metalized","offer_id":37858792734910,"sku":"5744903879","price":3695.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0423\/4104\/0296\/files\/louis-poulsen-ph-3-12-2-12-floor-lamp-5744901376-montreal-lighting-and-hardware-1.jpg?v=1738904201"},{"product_id":"louis-poulsen-ph-3-1-2-2-1-2-glass-shade-table-lamp","title":"PH 3 1\/2-2 1\/2 Glass Shade Table Lamp","description":"\u003cp\u003eThe PH 3½-2½ Glass Table lamp was designed in 1928 and is one of many advanced projects undertaken by Poul Henningsen in the development of his world-famous three-shade system from 1926. Poul Henningsen devoted most of his life to taming electric light. He based his three-shade design on a logarithmic spiral to make optimum use of the light source. He was constantly doing calculations and tests. The form of the shades was determined by the way they were required to shape and reflect the light, and the lamp was designed to be glare-free. The first PH Table lamp was completed in early 1927 and launched as an alternative to low-pitched hanging lamps. The white opal glass shades soften the overall look of the lamp and illuminate its surroundings with a perfect, harmonious and glare-free light that only the classic three-shade system is capable of emitting. The shades are mouth-blown three-layer opal glass, which is glossy on top and sandblasted matt underneath to provide soft and uniform light distribution.\u003c\/p\u003e","brand":"Louis Poulsen","offers":[{"title":"Brass","offer_id":37858792800446,"sku":"5744901868","price":2855.0,"currency_code":"CAD","in_stock":true},{"title":"Chrome Plated","offer_id":37858792833214,"sku":"5744903837","price":2635.0,"currency_code":"CAD","in_stock":true},{"title":"Black Metalized","offer_id":37858792865982,"sku":"5744903853","price":2855.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0423\/4104\/0296\/files\/louis-poulsen-ph-3-12-2-12-glass-shade-table-lamp-5744901868-montreal-lighting-and-hardware-1.jpg?v=1738904203"},{"product_id":"louis-poulsen-ph-3-1-2-2-1-2-table-lamp","title":"PH 3 1\/2-2 1\/2 Table Lamp","description":"\u003cp\u003eThe louvre is 100% glare-free, with a design based on the principle of a reflective three-shade system, which directs most of the light downwards.
