E27 UV-C Ozone Bulb Pair

This two-pack delivers 25 W UV-C lamps with dual 253.7 nm and 185 nm wavelengths in a standard E27 base. The quartz tubes provide 8000-hour rated life for continuous disinfection cycles. Each bulb weighs 0.23 kg and measures 50 x 268 mm for direct socket fit. Intended for rooms up to 400 sq ft where airborne impurities and odours need reduction.

Replaces Single-Wavelength Units

The combined UV-C and ozone output upgrades basic germicidal lamps by adding oxidative reach into fabrics and crevices. The jump is worth it when a single 253.7 nm source leaves shadowed areas untreated. Ozone generation allows the 360° coverage claim across mattresses, carpets and cushions. Occupants, pets and plants must vacate during operation and the space ventilated afterwards.

400 sq ft Effective Range

At 25 W the pair comfortably handles living rooms, classrooms, offices and restaurant sections up to the stated 400 sq ft. Beyond that area the intensity drops and treatment time rises sharply. The 8000-hour quartz life gives long headroom for scheduled cycles. No wiring or tools are required; simply twist into any E27 holder for immediate use.

Questions about this item

Will the 50 mm diameter and 268 mm length fit my E27 fixture?

The bulb measures 50 mm wide by 268 mm long and uses a standard E27 base, so it fits any fixture that accepts that size and base type.

What is the correct way to install the bulb and what step is often missed?

Screw the bulb into an E27 socket with the power off, then leave the room and ensure no people, pets or plants are present during operation.

How often will I need to replace each 25 W bulb?

Each bulb is rated for 8000 hours of use; replace it once that runtime is reached or if UV output noticeably drops.
