Ear-Shape UVC Bulb is a four-sided uva/uvc germicidal bulb series designed for Refrigerators, Disinfection cabinets, Fresh food cabinets. It uses 270-280 nm UVC + 395-405 nm UVA output with 1.5-7.5 W power and DC 12 V operation. The product data, optical output and dimensions are based on the Demo Photoelectric Technology catalog.
Integration and Safety
Use the specified power supply or constant-current driver, suitable thermal management and ESD protection. UVC radiation can damage skin and eyes; use interlocks, mechanical shielding, protective clothing and UV-rated eye protection during operation.
