VIQUA QL-410 Lamp and Sleeve Combo for VH410

The QL-410 combo pack is engineered to maintain the efficacy of your VIQUA VH410 UV system. The S410RL-HO UV lamp emits germicidal UV-C light at 254 nm, effectively inactivating harmful microorganisms such as bacteria, viruses, and protozoan cysts. Encasing the lamp, the QSO-410 quartz sleeve is made from 100% fused silica, offering high UV transmittance while protecting the lamp from direct water contact and maintaining optimal operating temperature. The included O-rings ensure a watertight seal during installation.
