The SIMBULB VINTAGE was meticulously designed to preserve the look of early-20th-century lighting using advance LED technology. The design of the LED structure uses a soft and bendable material as a substrate to create a beautiful curved filament which emits warm reddish glow that is perfect for mood and accent lighting.Designed by: Yeung Chi Keung of SIM Lighting Design Co., Ltd.Contact: andrew@simlighting.com; www.simlighting.com
