The Curalux CLCN-GUV40WD is a 40 W ultraviolet-C (UV-C) germicidal fluorescent tube that emits short-wave UV-C radiation — the wavelength widely used for microbial inactivation in professional disinfection systems. This double-ended T8 tube has a larger cap form factor compatible with fixtures engineered to house high-output germicidal lamps.
UV-C light at ~254 nm has been proven to disrupt the DNA and RNA of bacteria, viruses and other pathogens — helping neutralise microorganisms in air, water and enclosed surface sterilisation applications without chemicals.
⚠️ Safety Warning: UV-C radiation is hazardous to human skin and eyes. Only use this lamp in fully enclosed and shielded fixtures specifically designed for UV-C sterilisation. Direct exposure can cause serious injury.

• ☀️ Germicidal UV-C Emission: Designed to emit germicidal UV-C radiation that can inactivate microbes when used within sealed systems.
• 🔋 40 W Power Rating: Strong output suitable for mid- to large-capacity sterilisation equipment.
• 🔁 Double-Ended T8 Fluorescent Tube: Provides stable electrical contact in fixtures built for double-ended UV-C lamps.
• ✔ Professional Disinfection Use: Best suited for enclosed air purification units, water treatment chambers, surface sterilisation cabinets and industrial hygiene systems.
• 🧴 High-Transmission Materials: Constructed with quartz/UV-transmissive materials for optimal germicidal output.
• ⏱ Reliable Performance: Delivers consistent UV-C output when maintained and replaced at manufacturer-recommended intervals.
This 40 W germicidal tube is designed for enclosed sterilisation systems only, including:
✔ Air Disinfection & HVAC Sterilisation Units – installed inside enclosed air treatment fixtures to help reduce airborne microbes.
✔ Water Treatment Systems – used in water purification chambers to neutralise pathogens as water flows through.
✔ Surface Sanitisation Cabinets – ideal for enclosed cabinets used to disinfect tools, equipment or packaging.
✔ Industrial & Laboratory Hygiene Equipment – supports cleanliness in professional settings where controlled UV-C exposure is essential.
Note: The effectiveness of UV-C sterilisation depends on correct fixture design, lamp placement and exposure time. Always follow system manufacturer guidance for best performance.
UV-C radiation at short wavelengths (around 254 nm) carries enough energy to damage the genetic material (DNA/RNA) of microorganisms. When microbes absorb this energy, their cellular replication processes are interrupted — rendering them inactive. This process delivers chemical-free disinfection without residues or consumables, making it a preferred method in professional systems.
