OSRAM PURITEC HNS 6W G5 - UV-C 254 nm germicidal lamp (ozone-free) for disinfection of air, water and surfaces

The OSRAM PURITEC HNS 6W G5 is a low-pressure germicidal lamp that emits UV-C radiation at 254 nm (the effective wavelength for inactivating microorganisms) and does not generate ozone. With a nominal power of 6 W , a G5 base, and a T5 form factor (16 mm diameter) , it offers a compact and reliable solution for air, water, and surface disinfection systems in professional equipment. Its specific coating extends its lifespan, and its special glass blocks ozone-forming wavelengths. It is designed for integration into UV-C equipment and luminaires, not for general lighting, and must always be operated with appropriate safety precautions .

Main features

• UV-C 254 nm emission (OFR, ozone-free) for effective disinfection.
• UV-C radiation (200–280 nm) approx. 1.7W .
• Power/voltage/current: 6 W · 42 V · 0.20 A.
• Compact geometry: tube length 212 mm · diameter 16 mm (T5) · base G5 .
• Nominal useful life: 8,000 h (reference conditions).
• Burning position: universal.
• Not dimmable (dimming not supported).
• Low mercury content and no ozone formation .

Product benefits

• Effective disinfection without chemicals: a sustainable alternative to processes using biocides.
• Quality and stability: constant UV-C output when operated with the appropriate ballast/equipment.
• Easy maintenance: standard G5 T5 format facilitates replacement in compatible equipment.
• Environmental safety: no ozone emissions thanks to the filtering glass.

Use cases

• Air: treatment units/HVAC, duct recirculation, UV-C chambers and cabinets.
• Water: UV equipment for aquaculture, fountains and industrial processes (in closed reactors).
• Surfaces: disinfection chambers, UV-C boxes/cabinets and specific professional equipment.

Frequently Asked Questions

• Does it produce ozone? No. The glass in the PURITEC HNS series blocks the ozone-generating wavelength; the dominant emission is 254 nm.
• Is it dimmable? No. These lamps are not dimmable; they must be operated at their nominal setting.
• Which ballasts are compatible? It can be operated with electronic ballasts suitable for low-power T5 lamps (e.g., QUICKTRONIC QT-ECO 2x5–11/220–240 S ) or with magnetic preheating ballasts of the corresponding power (in this case, a starter is required ). Always check the equipment data sheet.
• Can I use it without a casing? No. UV-C radiation is dangerous for skin and eyes; it must be used in enclosed equipment or with adequate shielding and controls.

Installation and safety

For professional applications only. Avoid any direct or reflected exposure to skin and eyes. Integrate the lamp into enclosed UV-C luminaires or equipment with interlocks, timers, and shielding. Disconnect the equipment before any maintenance. Follow applicable regulations and the recommendations of the equipment and ballast manufacturer.
