OSRAM HNS 30 W G13 (PURITEC UV-C) - T8 254 nm OFR germicidal tube for disinfection of air, water and surfaces
The OSRAM HNS 30 W G13 is a low-pressure UV-C germicidal lamp in a T8 format (Ø 26 mm) designed for effective chemical-free disinfection . It belongs to the PURITEC HNS family and emits radiation with a dominant wavelength of 254 nm in an OFR (ozone-free) version, thanks to a special glass that blocks the 185 nm line to prevent ozone generation. With 30 W of electrical power, a nominal voltage of 96 V , and a G13 base, it delivers a typical UV-C radiated power of ~12 W , suitable for inactivating microorganisms in air , water , and surface purification systems. Its specific internal coating maintains stable UV-C emission and extends its lifespan. It is not dimmable and its working position is universal . Total length: 895 mm . Reference nominal lifespan: 9,000 h . For exclusive use in equipment designed for UV-C with appropriate protective measures.

Frequently Asked Questions
-
Does it generate ozone? No. The OFR version blocks the 185 nm line responsible for ozone formation.
-
Can it be used with people present? No. UV-C radiation can damage skin and eyes. Use enclosed housings, interlocks, and signage.
-
Does it need a ballast? Yes. It requires high-load T8 electronic ballasts. Typical example: QUICKTRONIC PROFESSIONAL QTP-OPTIMAL 1x18–40 (or other equivalent ballasts depending on the equipment design).
-
Is it adjustable? No.
-
How to manage maintenance? UV-C irradiance decreases over time; plan replacements according to the system's dose target.
Installation and safety recommendations
- Integrate UV-C shielding , interlocks, timers and signaling in accordance with regulations.
- In water treatment, use a clean quartz jacket and perform regular maintenance to ensure optical transmission.
- Avoid dust or grease on the tube; clean in cold water with a soft cloth and isopropyl alcohol.
- End of life: manage as waste with mercury content (low content).
Technical note on nominal values
The most recent OSRAM documentation (2025) specifies a lifespan of 9,000 hours and a nominal current of 0.40 A , while LEDVANCE datasheets (2023) list 8,000 hours and 0.36 A. Therefore, ranges are shown where applicable. The UV-C radiated power (~12 W) and dimensions (T8, 26 mm × 895 mm) remain constant across datasheets.
