Abstract
A lamp with an unpolished surface is herein described. The lamp comprises a closed body which comprises a source of light adapted to be connected to a source of power, contacts to connect said source of light to a source of power, and a cover. The cover is configured and disposed to permit light to exit the lamp when connected to a source of power. The cover comprises an inner surface facing the interior of the lamp and an outer surface facing away from the lamp. At least the outer surface facing away from the lamp comprises unpolished glass configured to provide the unpolished surface. The unpolished glass of the outer surface comprises a surface having a roughness which is minimized.
Claims21
