UVC light sources are subject to natural wear and tear. After approximately 8,000 operating hours, they no longer produce sufficient UVC output. It is then time to replace the bulbs. Original Oase UVC replacement lamps ensure performance like on the first day. Additionally, they guarantee the claims of the clear water warranty for you. Seemingly inexpensive bulbs from third-party suppliers often have different dimensions and do not fit into the lamp sockets or quartz glass. Or they only maintain the specified output for a very limited period. Such bulbs can have unpredictable effects on the UVC devices, especially the ballasts and internal components. This UVC lamp has a power consumption of 9 W. Suitable for, among others, BioPress 6000, FiltoClear 3000, BioSmart 7000.
