OSRAM PURITEC HNS L 36W 2G11 - UV-C germicidal lamp for disinfection of air, water and surfaces
The OSRAM PURITEC HNS L 36W 2G11 is a low-pressure germicidal lamp specifically designed for chemical-free UV-C disinfection . It emits radiation primarily at 254 nm (range 200–280 nm) and delivers 10.8 W of UV-C power , making it ideal for HVAC systems, surface disinfection chambers, and water purification/recirculation systems with quartz jackets. It features a 2G11 (4-pin) base, operates with electronic control equipment (ECG), and offers a long lifespan of 9,000 hours thanks to its special coating. It is ozone-free , has a low mercury content , and features an S180 burn-in position . Compact dimensions: length 408 mm , diameter 40 mm (max. tube 17 mm), and weight 102 g . For stable operation, the lamp operates at 106 V and 0.44 A ; reference luminous intensity: 7,800 cd (manufacturer's photometric data, not equivalent to visible flux).
Main features
-
UV-C technology (254 nm): effective disinfection of air, water and surfaces without chemicals.
-
Useful UV-C power: 10.8 W (200–280 nm) for easy sizing by dose (mJ/cm²).
-
Long service life: 9,000 h nominal with specific coating that maintains performance.
-
Ozone-free: does not generate ozone; less complexity in ventilation and materials.
-
Low Hg content: optimized to meet environmental and recycling requirements.
-
Base 2G11: compact 4-pin format, widely standardized in UV-C equipment.
Product benefits
-
Environmentally friendly disinfection: inactivates microorganisms by photolysis of DNA/RNA without chemical residues.
-
Optimized operating cost: extended life and maintenance of UV-C output thanks to the internal coating.
-
Easy integration: standardized dimensions (L 408 mm) and compatibility with standard electronic equalization.
-
Improved safety: ozone-free, which prevents the generation of O3 and simplifies extraction.
Use cases
-
Air treatment: HVAC ducts, fan-coil units, purifiers and UV-C chambers.
-
Water: quartz jacketed equipment for recirculation circuits, fountains and industrial processes.
-
Surfaces: disinfection tunnels and chambers in laboratories, pharmaceutical, logistics and agri-food.
Frequently Asked Questions
-
Does it need a ballast? Yes. It requires electronic equipment for 2G11 CFLs ; for reference, the QUICKTRONIC QTP-DL family (e.g., QTP-DL 2x36-40 ) is suitable for 36W 2G11 lamps.
-
Is it dimmable? No. Low-pressure UV-C lamps should not be dimmed; use ON/OFF operation with appropriate ECG.
-
Does it generate ozone? No, its dominant emission is 254 nm, outside the ozone generation band (~185 nm).
-
Does it inactivate pathogen “X”? Efficacy depends on the UV-C dose (mJ/cm²), distance, flow rate, and exposure time. Follow the equipment manufacturer's guidelines and applicable regulations.
Installation and safety
- Operate only within enclosed equipment ; UV-C radiation can cause eye and skin damage . Avoid any direct or reflected exposure.
- Respect the s180 burning position and ensure the thermal conditions specified by the luminaire.
- Use compatible materials (quartz, PTFE, anodized aluminum) and clean quartz jackets to maintain UV transmittance.
- Manage the lamp at the end of its life according to local regulations; it contains a small amount of mercury .
