Massena gives designer treatment to industrial lighting. We contrast the metal shade’s smooth dome with the collar’s strong details. Cutout vents cast upward light and reveal a pristine porcelain lamp socket. Massena’s interior is fully finished in white gloss to amplify downlight, while an etched glass diffuser, secured by diamond-knurled thumbscrews, softens shadows and shield eyes from glare.SpecificationsWidth/Diameter: 13.5"Height: 15.5"Min - Max Height: 21" - 75"Backplate/Canopy/Base: 7"Shade Material: MetalNumber of Lamps: 1Wattage: 150w ea.Socket Type: E26 Medium Base
