Compatible Replacement UV Lamp for Viqua VH200 UV System

The S200RL-HO AU is Compatible High Output Replacement UV lamp for VIQUA VH200 series of ultraviolet water treatment systems. ANNUAL LAMP CHANGE: After a year, the UV lamp needs to be replaced because it may not have enough intensity to kill bacteria after 9000 hours of use. UV light weakens and isn't strong enough to properly treat your water. Replacing your lamp annually with a genuine VIQUA lamp ensures optimal system performance.
