UVC light sources are subject to natural wear and tear. After approximately 8,000 operating hours, they no longer produce sufficient UVC output. At that point, it's time to replace the bulbs. Original Oase UVC replacement lamps ensure performance like on the first day. Additionally, they guarantee your claims under the clear water warranty. Seemingly inexpensive bulbs from third-party suppliers often have different dimensions and may not fit into the lamp sockets or quartz glass. Or they may only maintain the specified output for a very limited time. Such bulbs can have unpredictable effects on UVC devices, particularly on the ballasts and internal components. This UVC lamp has a power consumption of 7 W. It is compatible with, among others: Filtral 2500, BioPress 4000, BioSmart 5000.
