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 you have performance like on the first day. Additionally, they permanently secure your claims under the clear water guarantee. 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 UVC devices, particularly on the ballasts and internal components. This UVC lamp has a power consumption of 7 W. Suitable for, among others: Filtral 2500, BioPress 4000, BioSmart 5000.
