The UV Dynamics 400128 Replacement UV Lamp is specifically engineered as a direct replacement for the UV Dynamics UVD400 and compatible UV systems.

Additionally, timely lamp changes help extend the lifespan of your Ultraviolet Disinfection System Controller, protecting your investment.
UV Dynamics specializes in designing and manufacturing advanced Ultraviolet (UV) water disinfection systems tailored for household use. UV water disinfection is a proven and eco-friendly method that effectively eliminates harmful microorganisms without introducing chemicals. This technology provides an affordable, sustainable solution to safeguard your family’s water supply.
Environmental factors such as extreme weather, spring snow melts, and agricultural runoff increasingly threaten the safety of private water sources. Even municipal water supplies are not immune, with boil water advisories becoming more common across many communities. Unlike chemical disinfectants, UV water disinfection:
- Cannot overdose or alter the taste and odor of your water
- Produces no carcinogenic disinfection by-products
- Effectively neutralizes chlorine-resistant pathogens like cryptosporidium and giardia
Moreover, UV disinfection systems boast low operating costs and require no specialized tools for maintenance or lamp replacement, making upkeep straightforward and convenient. For detailed guidance, watch our instructional YouTube video linked above to assist with lamp replacement.
All UV Dynamics models feature both audio and visual indicators that alert you immediately to lamp failure, along with an annual lamp change reminder timer to keep your system functioning at peak performance. Many models also include an isolated low voltage solenoid drive circuit, enabling integration with an optional water shut-off solenoid valve for enhanced safety.
