We are proud to be an authorized seller of genuine Viqua brand systems. Viqua UV lamps are manufactured with high-quality components to exacting specifications to ensure performance and safety.
While knock-off UV lamps may seem to fit a Viqua system, their performance or safety simply cannot be guaranteed. If it’s not branded by VIQUA, it’s not a VIQUA lamp. Only use authentic Viqua brand lamps in your Viqua UV system.
Why Buy Genuine Viqua UV Water Purifier Lamps?
Using a genuine Viqua lamp is important for many reasons. This video below explains in more detail what can happen when a genuine Viqua lamp is not used.
What are the Risks When Using a Non-Viqua UV Lamp?
Viqua lamps are engineered to ensure safety and use only non-flammable materials.
A non-Viqua lamp may not disinfect properly, putting health of those in the household at risk.
| Using "knock-off" lamps in a Viqua system greatly increases the potential for equipment damage and even complete system failure. |
System performance could be compromised, and power supply failure may occur.
Viqua lamps are third-party certified (NSF55 and UL/CE) with accompanying UV system. This certification becomes void when a non-Viqua lamp is used in the Viqua system.

Using only genuine OEM Viqua lamps is your guarantee of total UV system performance and safety.
How Often Should a UV Lamp be Changed?
Viqua UV lamps are engineered to last for one year or 9000 hours. Many Viqua UV systems have built-in diagnostics to signal a warning when it’s time to replace the lamp.
UV lamps do not burn out – they solarize. This means that they gradually lose their light wave intensity to about 60% of what a new UV bulb provides. So even though your UV bulb may still illuminate brightly, it is not generating sufficient UVC energy to treat water properly and should be replaced. It is important to change the lamp on time so the UV system can effectively protect against waterborne microbes.

FAQs
Can I use a non-OEM or generic lamp in my Viqua UV system?
While generic lamps may appear to fit your system, using a non-Viqua lamp can compromise disinfection performance, void your Viqua system warranty, and potentially damage components. Only genuine Viqua UV lamps are tested and certified for safe and effective performance in Viqua systems.
How do I know which Viqua UV lamp model is compatible with my system?
Finding the correct Viqua UV lamp is simple! Just locate the model number on your Viqua system (for example, D4, S8Q, or VH200-F10) and enter it into our Replacement Lamp Finder Tool.

If you’re unsure of your model number or need help identifying your system, our friendly support team is happy to assist. Simply contact us with your serial number, and we’ll confirm which genuine Viqua replacement lamp you need.
How long does a Viqua UV lamp last?
Viqua UV lamps typically last for approximately 9,000 hours of continuous use, which translates to around 1 year of operation. Timely replacement of a Viqua ultraviolet bulb ensures optimal UV disinfection performance.
What’s the proper way to install or replace a Viqua UV lamp?
First, shut off the power and drain the chamber. Remove the old lamp carefully (avoid touching the quartz sleeve). Insert the new lamp into the socket, ensuring correct orientation. Refill, restore power, and reset any lamp-life indicators. Detailed instructions and video available here. Always follow the safety instructions in your Viqua manual.
Why does my Viqua UV lamp need to be changed every year even if it still lights up?
Over time, UV lamps “solarize” — they gradually lose UV output even though visible light remains. After ~9,000 hours (about one year), the lamp’s ability to disinfect water is significantly reduced, so replacement is necessary to maintain proper system effectiveness.
What is the warranty on Viqua UV lamps?
For a period of one (1) year from the date of purchase, Viqua warrants all genuine UV lamps and sleeves to be free from defects in material and workmanship. If your Viqua lamp or sleeve is defective, VIQUA will replace or repair the product. Give us call if you have questions: 469-521-9920.
