The Louis Poulsen PH 3½ - 2½ Color Table Lamp is a masterpiece designed by Poul Henningsen. Back in 1925 - 1926, Henningsen came up with the three - shade system, and the first lights using this system were shown at a Paris exhibition. His partnership with Louis Poulsen lasted until his passing in 1967. Throughout his career, Henningsen aimed to create lighting without glare. He focused on directing light where it was most needed, and using incandescent bulbs, he could create soft shadows. The PH 2/1 Pendant is part of the three - shade family, and there are 19 versions available today. Over the years, about a thousand models have been made, including table, floor, and wall lamps, as well as chandeliers that were quite popular in the 30s for high - ceilinged homes. Henningsen was the first to take a scientific approach to light, using the logarithmic spiral as a base. This design ensures an even spread of light across the shade's curve. Combined with the diffuse reflection through the glass, it effectively controls glare and shadows. Each shade reduces the light equally according to its distance from the source. The model numbers of PH lights indicate the shade size, with each top shade having matching middle and lower shades. The PH 2/1 Pendant has a top shade of about 20 cm and uses lower shades from the 1/1 model, introduced for hanging the pendants at lower heights. The lamp's louvre is completely glare - free, designed with a reflective three - shade system that sends most of the light downwards. For some versions, the top shade is made of deep - drawn aluminum with a white inner surface for a gentle, downward light spread. The two bottom hand - blown opal glass shades create a large glare - free light area, making the most of the light source for comfortable and useful lighting. Features of this lamp include being part of the PH Collection, designed by Poul Henningsen, having a reflective three - shade system directing light downwards, a white - painted underside of the shade, being able to use a 120V E26 (medium base) type B10 Incandescent lamp (wattage depends on fixture size), being UL Listed, and being available in green, red, white, or yellow. It has a size of 13' Dia x 17.7'H and a cord length of 120'. The shade is made of deep - drawn aluminum, and the base is silk matte brown and copper. This item comes with a 30 - day return policy.
Using your Louis Poulsen PH 3½ - 2½ Color Table Lamp is easy. First, find a suitable spot for it, like a bedside table or a reading nook. Plug the lamp into a 120V power outlet. If you need to replace the bulb, make sure to use a 120V E26 (medium base) type B10 Incandescent lamp, but note that the wattage depends on the size of the fixture. When it comes to cleaning, gently dust the lamp with a soft, dry cloth. For the glass shades, you can use a mild glass cleaner and a soft cloth to wipe them down. Avoid using abrasive cleaners or scrubbing too hard, as this could damage the lamp's finish. Also, make sure to turn off the lamp and let it cool down completely before cleaning.
