George Nelson originally designed the Half-Nelson Table Lamp for a large-scale design project, Holiday House, circa 1950. Holiday House was a commissioned vacation home for a magazine of the same name. It was intended to showcase the magazine and to promote a post-war economy where one could afford to own a vacation home. The lamp remained a prototype until 1977 when finally Koch & Lowy, an American Lighting Company, put the Half-Nelson into production until the mid-eighties.
It has been over twenty years since these lamps have been available. The subject of many auctions, especially on ebay, the Half Nelson is back is ints original grandeur from Modernica (the official licensor of all George Nelson Bubble Lamps). The Half Nelson is built to George Nelson’s original specifications. The lamp looks gorgeous on any table or desk setting as it blends sculpture with lighting innovation.
The 'Half-Nelson' Table Lamp utilizes a pivoting shade, which is adjustable both left and right and up and down—giving it the ability to direct light in all directions. The cylinder base and disc are both constructed of black powder-coated aluminum, while the underside of the disc is powder-coated white. The stem connecting the two is made of chromed-aluminum and the on/off switch is built of machined-anodized aluminum.
