The glassmaker''s craft of using an optic mold to create desired interior textures and designs was invented by Roman glassworkers and flourished in Venice in the Middle Ages. Using this ancient optic technique, we house a glass Bulbs (Not Included) in a hand-blown oval diffuser. This diffuser is perfectly clear on the outside with a wavy horizontal pattern worked in its Bulbs (Not Included)-facing side. These interior lines are in the optic tradition, valued in heritage pieces such as Depression glass.Specifications:Included canopy measures as 6"DiameterRequires 1 x 4-watt G9 Wedgebase Bulbs (Not Included) (Integrated)Voltage - 120300 Lumens, 90 CRI, 3000K Color TemperatureDimmableUL certified in compliance with nationally recognized product safety standards
