The Nelson Bubble Lamps are a versatile and unique addition to any interior with their various spherical shapes. The perfectly rounded shape of the Nelson Ball CrissCross Bubble Pendant has an interesting contour due to the bisecting pattern in its understructure. In 1952, Nelson was inspired by set of Swedish hanging lamps that were tediously crafted with a silk covering. The bigger challenge, however, was their expensive price. Nelson decided to make his own set, and arrived at an innovative process that replaced the silk shade with a translucent plastic material, making them available at a modest price.
