NNILight Low-Pressure Out of Arc UVC Lamps
The NNILight series offers powerful UV lamps for water disinfection, available in 800, 1000, and 1500 watts. These cost-effective, out-of-arc lamps provide high UVC output and lower maintenance costs, resulting in a reduced total cost of ownership compared to low-pressure lamps. Benefits include cleaner drinking water and improved water quality for agriculture, aquaculture, and food and beverage production.
The NNILight series provides reliable and cost-effective solutions, with the advantages of our out-of-arc (OoA) amalgam lamps. These state-of-the art UVC lamps are highly effective for water disinfection and advanced oxidation processes (AOP), offering economic and ecological advantages due to their long lifespan and optimized energy consumption. They maintain temperature stability across a wide range of water temperatures while dimming, enhancing the efficiency of your disinfection system. Additionally, NNILight out-of-arc lamps generate ozone, which helps eliminate chemical pollutants in the air and produce hydroxyl (OH) radicals in water for total organic carbon (TOC) applications.
Our customer focus sets us apart. We are committed to providing you with our expertise, experience, and guidance, making us a trusted partner. We have integrated the most advanced technology into our lamps, ensuring a robust design and reliable quality that satisfies your customers.
Lamps contain mercury. Manage in accordance with local, state or federal disposal laws.

Additional Resources
The NNILight series comprises high-powered low-pressure UVC lamps in 800 W, 1000 W and 1500 W ratings, engineered for water and advanced oxidation applications. These “out-of-arc” (OoA) amalgam lamps position the UV-emitting arc segment outside the main lamp envelope, enabling greater UVC output, better temperature stability and an extended service life compared to traditional low-pressure mercury lamps.
These lamps deliver significantly higher UVC power density: for example, the 1500 W model reaches a radiation flux at 254 nm of about 470 W. Subject to operating position (horizontal to vertical) and tube temperature (up to 150 °C), the robust quartz-glass design enables reliable use across a wide temperature range. Users benefit from fewer replacement cycles and reduced system downtime, which lowers total cost of ownership.
NNILight lamps are optimized for water disinfection (drinking, waste, industrial, aquaculture, agriculture) and advanced oxidation processes (AOP) where superior UVC output and ozone or hydroxyl radical generation improve total organic carbon (TOC) removal and chemical treatment. Their versatility extends to air treatment when configured for ozone generation, making them suitable for food & beverage production, process water systems and ventilation.
NNILight lamps are designed for high-power operation and extended service life. Their out-of-arc construction provides superior temperature control and minimizes mercury migration, ensuring stable UVC output even during long operating cycles: the robust quartz envelope and optimized amalgam design support consistent performance over thousands of operating hours.
By offering higher output per lamp, NNILight lamps enable a reduction in lamp count and/or reactor footprint, which lowers system head-loss and maintenance requirements. Their higher efficiency also supports lower energy consumption and reduced spare-part inventory. The design is presented as an “excellent economic and ecological choice” in industrial water treatment contexts.
Excelitas supports customization of the NNILight series in lamp bases and connectors; the lamps are available in ozone-generating or ozone-free versions to suit disinfection or advanced oxidation process needs. The modularity supports integration into new or existing installations, enabling system designers to match lamp geometry, power level and operating conditions to application requirements.
