While nodding to the past, the fixture also encompasses the future by incorporating the latest in LED technology. The medium based, vintage-style lamp warmly and charmingly glows due to microscopic LEDS that are combined to form a looped and delicate-looking “filament”. Gone is the use of inert gases and gone are the shortcomings of incandescent lamps only converting 5% of the energy they use into visible light. These LED lamps are bright and energy efficient as well as beautiful. Made with High quality Aluminum and ETL approved.
