Design George Nelson, 1947. Steel skeleton, self-webbing soft plastic. Made in USA by Modernica. It was in 1947 that George Nelson became inspired by a self webbing material used to moth-ball ships in New York and convinced himself it would be perfect for lighting. He made a metal frame, tracked down the source of the webbing material and by the next day he created a big glowing sphere and the Bubble Lamp was born. Modernica has faithfully reproduced the bubble lamps to the exact specifications using the original Howard Miller factory tooling. UL rated | 150 watt max. small: 15.
