UVC Germicidal Lamp UV Light Bulb 55W 254nm E27 with Ozone UVC Strong Sterilisation and Disinfection AC220-240V Perfect for Kitchen, Bedroom, Living Room, Office and School Fresh Air(1 Pcs) [Energy Class C]

Superb . Does exactly as its supposed to do .. vent those rooms well after youve used it as it really puts out some ozone …

This is a large halogen style bulb with an E27 screw-style fitting.It says not to look at it but people, pets, plants should not be in the room when it is turned on. Also, the room should be ventilated for 1 hour after to air out the ozone.So we have this plugged into a lamp and then use an extension cord to plug into a socket outside the room. This way you can switch it on and off without ever being in the room while it's working.Not sure whether it needs to shine directly on a surface to work. It says it covers 55sqm. Better information would be helpful on how to use it most effectively.I've no way to test whether it's killing germs, dust mites, etc. But get an added sense of security using this. Particularly in the kitchen after cleaning surfaces with ordinary dish washing liquid. Much prefer to use this than chemical cleaners. Think we all eat and breathe way too many chemicals these days so this helps reduce the overall toxic load.Says will last 5000 hours.Hope that helps.

Do you own research on UVC / Ozone devices.They have, in my opinion, greatly exaggerated the potential benefits whilst minimising the high risk to health (not to mention the odious, pervasive smell) of the ozone gas generated.

The BrightArk 55W UV lamp uses a 254nm UVC wavelength for disinfection, providing a germicidal rate of 99.9%, equivalent to 30 times natural sunlight, significantly improving hygiene. The lamp also produces ozone, enhancing disinfection and removing odours, especially in hard-to-reach areas like under the bed. With a lifespan of 5,000 hours, it reduces maintenance costs and replacement frequency, making it an affordable, long-lasting solution for indoor air purification. The UV sanitizer bulb offers 360° coverage and fits any standard E27 lamp holder, eliminating mites, viruses, and bacteria, freshening the air, and reducing disease risks for humans and pets. It’s ideal for home use and professional settings, effectively sterilising, removing odours and mould, and enhancing air quality in areas up to 55 square meters.You must keep people, pets, and plants out during disinfection, avoid direct eye exposure, ventilate well after use to dissipate ozone, and clean regularly for optimal performance.I tested this bulb in my bathroom as per the recommendation, and I found no annoying flying fruit flies in there like before. I'm unable to test if it did sanitize the room, but the light certainly bathed everything, so everything seems well. The bad smells in the room seemed to go, and I did notice a kind of ionized smell, nothing unpleasant, though.In summary, the BrightArk 55W UV sanitizer lamp seems to be an effective and reliable solution for enhancing hygiene and air quality in your living space. Highly recommended! ✨

Not sure how long it was on for because I wasn't in the room for obvious reasons. But when I returned, it was off and won't turn on again. Disappointed
