UV-C + Ozone Air Treatment

This four-pack of 25 W E27 bulbs emits 253.7 nm UV-C and 185 nm ozone-generating light for room-scale air and surface treatment. Each quartz-tube lamp fits a standard E27 socket and is rated for 8 000 hours of operation. The set suits living rooms, classrooms, offices and restaurants up to 400 sq ft. People, pets and plants must leave the area during use.

Replaces Single UV Tubes

Swapping a single lower-wattage UV tube for this 25 W four-bulb kit increases total UV-C output and adds 185 nm ozone production for odour reduction. The upgrade is worthwhile when a space needs broader 360° coverage or faster treatment cycles across multiple rooms. Single-bulb fixtures without ozone capability cannot match the combined wavelength reach.

400 sq ft Coverage with 8 000-Hour Life

One bulb treats up to 400 sq ft; the pack provides spares or multi-room deployment. Effective intensity drops beyond the rated area and in shadowed corners behind furniture. Ozone generation requires post-use ventilation until the air feels fresh. The 8 000-hour rating assumes continuous operation; frequent on-off cycling may shorten practical lifespan.

Questions about this item

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

Each bulb measures 50 mm wide by 268 mm long, so check that your E27 socket has at least that much clearance before installing.

What is the correct way to install the E27 base and what step is often missed?

Screw the bulb into the E27 socket until fully seated, then ensure the room is empty of people, pets and plants before switching it on.

When should I replace the bulbs after reaching the 8000 hour rated life?

Replace all four bulbs once they have accumulated 8000 hours of use, as UV output drops below effective levels after that point.
