Submersible UV Germicidal Lamp

Engineered for reliable underwater disinfection, this UV germicidal lamp functions at 220V with EU plug compatibility and uses quartz glass for optimal UV-C emission. It comes in eight power options — 5W, 7W, 9W, 11W, 13W, 15W, 18W and 22W — with corresponding physical dimensions: 20 cm for 3W–7W models and 23 cm for 9W–13W variants. A 210 cm cable supports flexible routing in varied installations. Its tail is made of insulating material and reinforced with multi-stage sealing rings to guarantee waterproof integrity during extended submersion. Package contains one UV lamp tube, one suction cup mount, one controller and one EU power plug. UV-C irradiation disrupts microbial DNA replication, thereby controlling bacterial blooms and limiting algae development in enclosed and semi-open aquatic systems. The integrated power switch allows instant toggling between operational states, enhancing user control and reducing plug wear. Its amphibious design accommodates both full immersion and partial exposure — ideal for aquariums, koi ponds, decorative water features and small hatchery tanks. No external ballast or housing required — the lamp operates independently once mounted and powered, streamlining setup for hobbyists and semi-professional users alike.
