What Are UVC Germicidal Lamps?
UVC germicidal lamps are low-pressure mercury vapour lamps that emit ultraviolet radiation at 253.7nm, a wavelength that is highly effective at deactivating bacteria, viruses, moulds, yeasts and other microorganisms. Unlike chemical disinfection, UV-C leaves no residue and does not alter the taste, odour or chemistry of the treated water or air. Germicidal lamps are used worldwide for drinking water treatment, wastewater treatment, air disinfection and surface sterilisation across healthcare, food, laboratory and industrial applications.
UVC Lamp Types Available

UVC Lamp Manufacturers We Stock
We supply genuine UVC germicidal lamps from the world's leading manufacturers, covering the full range of wattages, base types and form factors.
Replacement UVC Lamps
UV-C output depreciates over time, so germicidal lamps should be replaced at the end of their rated life even if they still produce visible light. We stock replacement germicidal lamps for all major UV system manufacturers, including Wedeco, Trojan, Hanovia, Degremont, Atlantic UV and others. If you know your system model or lamp reference, use our cross-reference search tool to find the correct replacement. If not, use our Find My Lamp service and our specialists will identify it from the lamp reference, machine model or a photograph.
Safety Considerations
UVC radiation is harmful to skin and eyes. Germicidal lamps must be installed in enclosed systems that prevent direct exposure. Always follow the manufacturer's safety instructions, wear appropriate protective equipment when handling lamps, and ensure power is disconnected before lamp replacement. UVC lamps should never be operated in occupied spaces without proper shielding. For technical guidance on safe lamp replacement, see our Technical Information Centre or call our specialists on 01494 838 389.

Frequently Asked Questions
What is a UVC lamp?
A UVC lamp is a low-pressure mercury vapour lamp that emits ultraviolet radiation in the UVC band (200-280nm). The most common germicidal wavelength is 253.7nm, which is highly effective at deactivating bacteria, viruses and other microorganisms by damaging their DNA or RNA.
What are germicidal lamps used for?
Germicidal lamps are used for disinfecting drinking water, wastewater, swimming pool water, air in HVAC systems and clinical environments, and surfaces in food processing and medical facilities. They are also used in aquarium and pond sterilisers and in stand-alone air purifiers.
What wavelength is commonly used for germicidal UV?
The most common germicidal wavelength is 253.7nm (often rounded to 254nm), which is the peak output of low-pressure mercury lamps. This wavelength is in the UVC band and is highly effective for microbial inactivation.
What is the difference between UVC and germicidal lamps?
The terms are often used interchangeably. UVC refers to the ultraviolet C band (200-280nm). Germicidal specifically refers to lamps designed for microbial disinfection, which typically operate at 253.7nm within the UVC range. All germicidal lamps are UVC lamps, but not all UVC lamps are necessarily marketed as germicidal.
How long do UVC germicidal lamps last?
Rated life varies by manufacturer and type. Standard germicidal lamps typically have a rated life of 8,000-9,000 hours, while extended-life versions can reach 16,000-36,000 hours. UV output depreciates over time, so lamps should be replaced at the end of their rated life even if they still produce visible light.
Which manufacturers produce UVC germicidal lamps?
We stock UVC germicidal lamps from Philips (TUV range), Osram (Puritec HNS), Sylvania (G-series), Tungsram/GE (G-series and Biax), LightTech (quartz and amalgam), and LEDVANCE (UVC T5, T8 and compact ranges).
Can you cross-reference a discontinued germicidal lamp?
Yes. We maintain a cross-reference database covering competitor and OEM lamp codes. If your germicidal lamp has been discontinued, we can identify an equivalent or compatible alternative from a current manufacturer. Use our cross-reference search tool or the Find My Lamp service.
Are UVC lamps safe?
UVC radiation is harmful to skin and eyes. Germicidal lamps must be installed in enclosed systems that prevent direct exposure. Always follow the manufacturer's safety instructions, wear appropriate protective equipment when handling lamps, and ensure power is disconnected before lamp replacement. UVC lamps should never be operated in occupied spaces without proper shielding.
