UVC LAMP
High-Performance Quartz UVC Germicidal Lamps & Ultraviolet Solutions
Kavri Quartz Product Co., Ltd. is a verified Chinese manufacturer and exporter specializing in high-purity quartz envelopes and precision ultraviolet (UVC) germicidal lamps. Based in Donghai, Lianyungang City, Jiangsu Province — the renowned hub of China's quartz and silica industry — we utilize superior raw materials, state-of-the-art quartz processing equipment, and rigorous vacuum sealing technology to engineer custom UVC lamps with extended service lives and exceptional ultraviolet output efficiency.
Our germicidal UVC lamps are engineered primarily at the critical 253.7 nm germicidal wavelength and 185 nm ozone-generating wavelength. Serving equipment builders and OEM distributors worldwide, Kavri Quartz supports complete customization across glass envelope types (synthetic, ozone-free, or doped quartz), base terminations (4-pin, 2-pin, double-ended, or custom ceramic sockets), operating wattages, and arc lengths.
