UV Germicidal Lamp 185nm UVC with Ozone Light Bulb E27 20w 220v Cleans Air

I have used this lamp a few times at 30-40 minute bursts for a medium sized room. So far the lamp has not failed as mentioned by other reviewers. I will update my review if or when it does. This lamp is 20w, I don't suggest trying for the 35w one, especially if you have to manually turn the light off and on. Consider getting a timer, or other automation device. I suggest this because the seller does not make it clear enough that UVC is damaging to skin and DNA, and the ozone produced can chemically react in your lungs. I assume its okay to expose yourself for a couple seconds, but I don't suggest taking deep breaths of ozone, just incase you like the smell, like how some people love the smell of petrol. the light switches are typically by the door, I leave the room, and flip the switch with my eyes closed. I also leave my fan and air filter running. when it is time to turn it off, I close my eyes, and hold my breath in order to not inhale the ozone. You can leave the room sealed, but it will take at least an hour for the ozone to dissipate. Or you can can hold your breath while you open any windows, and this will speed up the process. To summarize, this bulb does what it says. It produces UVC light, and it does produce ozone. I have not seen it kill any spiders, and I don't know if it can kill mites. but I do know once you have used the light for 30-60 minutes, and aired out the room. The room does smell fresh.

Be careful using this light, it produces Ozone which can damage lungs - but it is fantastic at killing bacteria, mold, smells. Whenever I get a whiff of dampness - I close off the room and turn this bulb on remotely for an hour, then air for a few hours. Yes it does smell at first - however all the bacteria / mould etc in the room will be gone! I do each room every month or so.

This UV-C germicidal lamp is very good value for money. It gives out around 25W of light and is very powerful. The frequency of UV light sits right on the middle of the UV-C band, giving a clinically clean feel to any room. Always ensure that you air out the treated room for 20 minutes after treatment in order to allow all O-Zone gasses to dissipate. Although O-zone is not harmful if inhaled, it does have a distinct odour which is mildly unpleasant.

It works and produces ozone, I can't say how effective the UV is though...

Great quality worked out for long use.

Made me very sick did all the guidance but very dangerous debating about referring to trading standards

Very good light and powerful germicide. Creates an unpleasant ozone smell but this quickly dissipates once you open the door or window. Have had this for about 2 years now and still going. Have bought a second one for my family as a recommendation. Remember never to look at this light.

Bulb did what it said on the tin. Used it for two years monthly to prevent mould growth due to allergy to mould. It did the job and even enabled me to have cleaned and disinfect fungus damaged sentimental furniture and the mould never came back. Sadly after a session recently I broke the lamp accidentally so will need to rebuy. I used for not more than 30 minut s per session. Absolutely produced ozone.
