TUV T5 Germicidal Lamp 4W G4

Common uses for TUV 4W T5 germicidal UV (UVC) lamps (often marketed as “TUV 4W G4/G5 T5”) are generally small, enclosed disinfection and sterilisation applications where a compact UVC source is needed.

Point-of-use water disinfection

Small UV water purifiers, countertop units, inline modules for low flow rates. Used to inactivate microbes (bacteria, viruses, protozoa) by damaging DNA/RNA.

Air and HVAC disinfection (enclosed)

Small in-duct or in-unit air steriliser modules. Often paired with a fan and reflective chamber to increase dose.

Surface disinfection in enclosed boxes

UV sterilisation boxes/cabinets for small items (e.g., tools, phone/keys, lab accessories), assuming the design provides sufficient dose and shielding.

Laboratory / medical / dental equipment (compact chambers)

Disinfection of instruments or work areas inside enclosed UV cabinets (not a replacement for autoclaving where sterilisation standards are required).

Aquarium / pond filtration (small UV clarifiers)

Used to reduce free-floating algae and some microorganisms in circulating water systems.

Food and beverage equipment (niche, enclosed)

Small UV chambers for process water or for surface exposure inside machinery where shielding and compliance are managed.

Odour control / coil and drain pan hygiene (HVAC micro-units)

UVC used to suppress microbial growth on wetted surfaces inside air handlers (more common with higher wattage lamps, but small lamps exist for compact units).
