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 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 diffused, warm or cold light was desired. Glass was later introduced for the three-shade system.\u003c\/p\u003e\n\u003cp\u003eIn 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 an 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.\u003c\/p\u003e\n\u003cp\u003eThe 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 (7.87 inch), with corresponding lower shades. PH 4½-3½ Glass Table consists of an approximately 45 cm (17.71 inch) top shade but uses lower shades from the 3½ model. These hybrid models were introduced due to the desire to hang pendants at lower heights. The system was also used for wall, table, and floor lamps. PH 4½-3½ Glass Table in its current form was introduced in 1990.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDesigned by \u003c\/span\u003ePoul Henningsen.\u003c\/p\u003e\n\u003ch5\u003eMaterials\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eBase: High luster chrome plated, spun brass. \u003c\/li\u003e\n\u003cli\u003eShades: Hand blown white opal glass.\u003c\/li\u003e\n\u003cli\u003eAnti-glare ring: Purple, spun aluminum.\u003c\/li\u003e\n\u003cli\u003eTop plate: High luster chrome plated, spun brass.\u003c\/li\u003e\n\u003cli\u003eStem: High luster chrome plated, steel.\u003c\/li\u003e\n\u003cli\u003eClass: cULus, Dry location.\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCord type: Black. \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCord length: 9’. \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSwitch: In-line on\/off switch provided.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eDimensions\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003e \u003c\/strong\u003e21.7 H x 17.7 Dia. inches;
