Viqua S410RL-HO Replacement UV Lamp - Reliable UV Disinfection

Our review of the Viqua S410RL-HO Replacement UV Lamp finds it best suited for homeowners and technicians who already own a compatible VIQUA UV system and want a genuine OEM lamp to maintain water treatment performance. The lamp's single biggest appeal is straightforward: it restores the system's UV intensity with an authentic replacement designed for the VH410 family and related models, ensuring microbial protection when replaced annually. For those who prioritize a plug-and-play, manufacturer-approved component, this lamp provides predictable performance and peace of mind.

Key Features

• Compatibility: Designed specifically to fit VH410, VH410M, SC-410, SCM-410 and several SPV and SP models so installation is straightforward in those systems.
• Reliable disinfection: Provides the UV intensity needed to deactivate DNA in protozoan cysts, bacteria and viruses when used in a functioning VIQUA system.
• High output design: The mercury vapor high output lamp offers compact but strong UV intensity, helping the system deliver effective treatment.
• Maintenance clarity: VIQUA recommends annual replacement to ensure the lamp continues to provide the required UV dose, simplifying upkeep.
• Genuine OEM part: Being an original VIQUA replacement helps avoid fit and performance problems that can come with generic lamps.
• Careful packaging: Double-boxed and bubble wrapped to reduce transit damage and support safe delivery.

Who It's For

This lamp is for owners of VIQUA VH410, VH410M, SC-410, SCM-410, SPV-410, SP410-HO, SPV-8 and PUV-14 systems who need an exact OEM replacement to restore proper UV output. It suits those who prefer a manufacturer-approved part, want easy installation with a precise fit, and plan routine annual maintenance to keep microbial protection effective.

It is not for users seeking a lifetime component or for systems from other manufacturers; people who want a longer-lasting, nonmercury option or who have concerns about fragility may want to explore other sterilizer technologies or lamp types. Those who do not own a compatible VIQUA model should not purchase this lamp.
