PLS lamps come in a range of sizes and will fit most brands of UVC.
The PLS UV lamps have two pins at one end only.
To keep your pond water clear UVC Bulbs should be changed at regular intervals. We recommend that UV Lamps are ideally replaced in the spring before the pond season starts. This guarantees your UVC is functioning at optimum performance when you need it most.
High quality replacement UV Lamps. PLS design
