Originally introduced in the 1950's, Doo-Wop was designed in close cooperation between the Navy Buildings Department and Louis Poulsen. The pendant was used for many years in the builidngs of the Navy for many different applications such as cateens and offices. The Navy Pendant, which was the name at that time, was widely used because of the unique lighting properties and utility. Not until the early 1980's the product was taken out of the Louis Poulsen catalogues. In recent years, more and more of the old editions have been sold again through antique stores and auctions. This has caused a demand and Louis Poulsen has been asked to re-launch the products. The new version is very close to the original. However, the colors have been updated to correspond to the colors of the time, while the production methods are the same. The shades are still spun by hand and completed with the fine rolled edge which gives the shades a special opticial volume. The brass variant challenges the craftsman as it is spun from a solid brass plate and appears polished.
