OSRAM AirZing PRO 5040 - 36W UV-C Luminaire for Air and Surface Disinfection (with IR Sensor)
The OSRAM AirZing PRO 5040 is a germicidal UV-C luminaire at 253.7 nm , designed to reduce microbial load in the air and on exposed surfaces . It incorporates a 36 W PURITEC HNS T8 lamp , an infrared (IR) sensor for automatic shut-off upon presence detection, and a 30-second start-up delay for enhanced operational safety. It operates at 220–240 V~ (50/60 Hz) , with a power consumption of 40 W , a power factor >0.9, and THD <20%. It is easy to install on walls or ceilings , and a recommended height is between 2.5 and 4 m , with cycle times depending on the room size.
The effectiveness of UV-C disinfection depends on the dose (irradiance × time), distance, angle of incidence, and shadows. As a practical guide, for a mounting height of 3 m, the following exposure times per unit are recommended: <10 m² → 30 min ; 10–15 m² → 45 min ; 15–20 m² → 60 min ; for larger areas, use multiple units . The AirZing PRO 5040 is ozone-free and is designed exclusively for indoor UV-C disinfection , not for general lighting.
Main features
-

-
UV-C Irradiance/Output: UV-C emission 14–15 W; initial irradiance ≈ 1.4 W/m² @ 1 m ; at 9,000 h ≥ 1.10 W/m² @ 1 m (typical reference values).
-
Recommended installation height: 2.5–4 m (from the ground).
-
Mounting: wall or ceiling; metal housing with G13 lamp holder.
-
Environment: operating −10 °C…40 °C; storage −20 °C…60 °C; RH ≤ 80 %.
-
Dimensions and weight: 1,363 × 54 × 78 mm; 1.5 kg net.
Product benefits
-
Chemical-free disinfection : reduces up to 99–99.9% of exposed microorganisms (depending on dose and conditions), useful as a complement to hygiene protocols.
-
Safe operation : Automatic presence cut-off and ignition delay minimize the risk of accidental exposure.
-
Predictable maintenance : lamp life of 9,000 h and irradiance reference at 1 m to plan replacement.
-
Simple implementation : wall or ceiling installation and indicative cycle times per surface for quick sizing.
Use cases
-
Waiting rooms, consultation rooms and offices (disinfection cycles between occupancies, without people present).
-
Commercial spaces and warehouses with regular protocols for disinfecting the air and exposed surfaces.
-
Production areas and technical rooms where reduction of environmental microbial load is required.
Note: This light fixture is not a water treatment system. Specific closed-channel UV-C reactors are required for water treatment.
Coverage and exposure times (guide)
-
Reference installation height: 3 m from the ground.
-
<10 m²: 30 min
-
10–15 m²: 45 min
-
15–20 m²: 60 min
-
>20 m²: use multiple units.
UV-C irradiance measurement (on-site quality control)
- Place the UV-C meter 1 m from the lamp and turn on the light fixture.
- Wait 5 min for heating and record the irradiance in µW/cm² .
- With stable voltage (≈ 230 V), the initial irradiance should be ≥ 90 µW/cm² (≈ 0.90 W/m²).
- Consider the lamp to be at end-of-life if its wattage falls below 70 µW/cm² (≈ 0.70 W/m²). Replace the lamp.
Frequently Asked Questions
Can it be used with other people present?
No. UV-C radiation can damage eyes and skin. The light fixture should be operated without people or animals present and with the area isolated during the cycle.
Does it include the UV-C lamp?
Yes, it includes OSRAM HNS T8 36 W and an integrated IR sensor.
Does it generate ozone?
No. The emission is at 253.7 nm ( without ozone ).
How do I determine the number of units?
Take the surface area and apply the guide times per unit. For >20 m², increase the number of luminaires or the total time.
What maintenance does it require?
Periodic cleaning of the lamp and filter/screen, verification of irradiance and replacement of the lamp approximately at 9,000 hours if the irradiance falls below the indicated threshold.
Safety and best practices
- Wear UV-C protective glasses and clothing during maintenance operations.
- Install a separate switch > 2 m from the floor, with a lockout for use by authorized personnel.
- Do not use the equipment near flammable/explosive materials or obstruct air inlets/outlets.
- Keep the enclosure closed, clean, and dry during the cycle; do not use fans while the lamp is on.
-
Disconnect before any intervention and respect local regulations for the management of mercury lamps .
