OSRAM PURITEC HNS L 55 W 2G11 - UV-C Lamp 254 nm (OFR, ozone-free) for disinfection of air, water and surfaces

The OSRAM PURITEC HNS L 55 W 2G11 is a low-pressure germicidal lamp designed for chemical-free UV-C disinfection systems. It emits radiation with a peak at 254 nm ( OFR version, ozone-free) and delivers 17 W of UV-C radiant power in the 200–280 nm band. Operating at 101 V and 0.55 A with a nominal power of 55 W , it features a 2G11 base and a nominal lifespan of 9,000 hours . Its design is optimized for installation in ducts and air/water treatment equipment, disinfection cabinets, and surface applications, with an s180 burn-in position and low mercury content . For reliable operation, OSRAM recommends its use with Quicktronic QTP-DL 2×55 GII electronic ballasts (non-dimmable).

Main features

• UV-C at 254 nm (OFR, without ozone generation) for effective disinfection.
• UV-C radiant power: 17 W (200…280 nm).
• Electrical: 55 W · 101 V · 0.55 A.
• Base: 2G11 (4 pins).
• Format: diameter 40 mm · length 533 mm.
• Durability: nominal life 9,000 h thanks to specific coating.
• Operation: burn position s180 ; use with dedicated electronic ballast (non-adjustable).
• Safety: Germicidal UV-C lamp for use in enclosed spaces with protective measures.

Product benefits

• Fast and environmentally friendly disinfection : no chemicals or ozone byproducts.
• Stable performance throughout its lifespan thanks to the tube coating.
• Easy integration into professional equipment due to its 2G11 standard and compact dimensions.
• Reduced maintenance due to its long service life.

Use cases

• Air treatment : UV chambers in AHU/AHU, HVAC ducts, recirculation in technical rooms.
• Water treatment : compact through-unit equipment and tanks (with specific UV-C design).
• Surfaces : cabinets, tunnels and disinfection lines in logistics, food, laboratory and healthcare.

Frequently Asked Questions

• Does it generate ozone? No. The OFR version uses glass that blocks wavelengths that would produce ozone.
• Is it adjustable? No. It is used with non-adjustable electronic ballasts (e.g. QTP-DL 2×55 GII) to ensure stability and service life.
• Is it suitable for illuminating people/occupied spaces? No. UV-C radiation can cause eye and skin damage . It must be contained in enclosed equipment or with appropriate shielding.
• What maintenance does it require? Preventive replacement according to hours and periodic verification of UV-C power (measurement with a radiometer).

Installation and safety recommendations

• Install only on equipment designed for UV-C , with shielding, interlocks and signaling.
• Use the electronic ballast recommended by the manufacturer (Quicktronic QTP-DL 2×55 GII or other compatible 55 W/2G11, non-dimmable).
• Avoid direct or reflected exposure; use appropriate PPE during maintenance.
• Ensure cleanliness of the lamp and optical surfaces to maintain irradiance.
