Voskilon 2 Pack 55W Watt Replacement UV PLL Pond Bulb, Ultra-Violet Bulb Spare 530mm UVC Lamp for Filters, Clarifiers

【UV Filtration Replacement】 The pond uv light replacement set contains two 55W UVC tubes for use inside a compatible enclosed UV filtration unit. Each 530mm lamp is intended as a uv bulb for pond filter maintenance spare, helping pond owners replace a matching worn tube without changing the complete filter unit. 【Quartz Tubes and 2G11 Cap】 Made with quartz and a 2G11 4-pin connection, each uv bulb for pond filter is designed for equipment that specifies the same 55W lamp, cap configuration and tube dimensions. Check the original lamp and filter manual before ordering; the matching socket alone does not establish compatibility. 【For Pond and Aquarium Filter Owners】 For koi pond keepers, garden fish pond owners and aquarium filtration users replacing an existing compatible UV tube. This uv light for pond application is intended for enclosed filter systems, not exposed decorative lighting; verify the unit uses a 55W 2G11 four-pin lamp before replacing it. 【Two Matching Replacement Lamps】 A 2-pack provides two spare 55W tubes for a compatible filter maintenance routine or for keeping one ready for a later replacement. The uv pond light replacement format suits owners who want the same 530mm specification in one purchase; the pack includes lamps only, not a complete pond UV unit. 【Check Fit Before Installation】 Measure the original lamp and confirm 530mm length, 17mm tube diameter, 55W rating and 2G11 four-pin cap. This uv bulb for pond filter must only be fitted to the specified enclosed UV equipment with the power disconnected. Never run the lamp exposed or look directly at an operating UVC tube.
