BAIMNOCM 2 Pack UVC Light Bulb Ozone Free, UV Lamp 25 Watt, 254nm Weavelength UV-C lamp for Basement E26 Base 2 Count

For the record, I am reviewing: BAIMNOCM 2 Pack UV Light Bulb with Ozone 25 Watt UVC Bulb 185nm/254nm E26 2 CountI purchased a 15 watt UVC bulb back at the beginning of the Covid Pandemic. My husband works at the VA and he sees a lot of sick patients. Some of them would lie and say that they did not have a fever or cough just so that they could get their appointment completed as they were having to wait for a long time, at that time, for an appointment. We instituted an isolation and decontamination policy for home that included him going directly to the garage after work, undressing and putting his clothes into the washer. He then put all his other items, like keys, wallet, badges, and such into a box and we set that just under the 15 watt light bulb that we would turn on for 15 minutes to decontaminate everything. Then he would go and take a shower and put on fresh clothes. It worked. neither of us has ever had covid, our vigilance worked.He got sick with this flu that is going around and it turned into pneumonia and sepsis. We isolated him in one bedroom and put the 25 watt UVC light bulb in the bathroom. After he uses the bathroom we turn the bulb on and shut the door. After 30 minutes the room is sterilized. When you open the door the smell of ozone is present. That means it is CLEAN. Ozone is a good thing. But you have to air out the room before entering. So far, three weeks now I have been safe and not gotten sick, and I usually get anything that he gets and brings home. I credit the UVC light and our isolation procedures. For anyone that is concerned with the number and type of bugs going around, I would HIGHLY recommend these bulbs. They are powerful enough to clean a 10x12 room within 30 minutes or less. Just do not look at the light when it is on.

Most reviews seem to be complaints about well-established effects of UV sanitization.Do they stink? Yes. UV-C will product stink, this is a byproduct of sanitization.How much do they stink? It depends how much sanitization was done: stink=VOC's. The EPA and FDA claim the VOCs produced by UV-C light are harmless, and scientifically there is no reason they would be since they are essentially airborne "dead cells."I was verifiably able to determine these lights emit almost no ozone using my Klein gas detector. VOCs unsurprisingly go off the chart (mine were 700ppm before UV-C, then 2000ppm, and finally settled down to 500ppm) until the area has been sanitized AND filtered. That second part is important: if you want to actually clean your air instead of just sanitize it, you need to collect the dead particulate matter floating around. This is why common applications for UV-C are inside HVAC air handlers BEFORE and AFTER the filter, but if only using a single UV-C, I recommend placing it before the filter if possible. This is generally not possible if your filter access is at the return intake and not inside the HVAC unit\duct. Eventually the airborne particulate will be filtered but...you will smell it. Alternatively you can run a room HEPA filter to collect it.So far I have two bulbs running pre and post filter, inside the return vent before the filter, and one after the heat exchanger. I'm curious how long the bulb life will be exposed to 180F heat as these E26 base bulbs are clearly not designed to be fixed inside duct work, but using a NEMA15>E26 adapter and making a mount out of sheet metal, I riveted a bulb mount to my ducts, drilled a 7/8" hole for the filament of the bulb to insert into the duct, and appropriately leak-sealed with high-temp foil duct tape.Very economical solution compared to Honeywell and other brands that charge $100-$150 for equivilent bulbs, all of which seem to be ozone-emitting. While ozone sanitizes more, controlling the "medical office" smell they produce is extremely challenging in a residential setting as it collects inside fabrics.

I’m stunned this is $100. They look incredibly cheap, and one arrived with a defective bulb; No cracks or visible damage, it simply won’t light up.EDIT: ** -> ****So after I left my review, I was promptly contacted by the seller and they sent me replacements. I gave +1 star for the quick customer support and another +1 since it seems to accomplish what it does as advertised. The smell it leaves behind reminds me of how my clothes would smell after my mother left them out to dry on a clothesline on a sunny summer day, only much stronger.I can’t give it a 5 star though because while the quick support was appreciated, this still does seem to be an over-priced and defective product based off my own experience and the experiences of other reviews I’ve seen here. Buyer be warned: there’s a good chance that at least one of your bulbs won’t work on arrival.

All 4 came fully functional. I verified them with a UVC meter. Verified that they didn't produce ozone (ozone wavelength well blocked by the bulb coating). The only point to note is that when turned on from cold, it takes the bulb 50-60 seconds to reach its full output. But then, if turn it off and back on, the full output is immediately available.

These work great on mold and bacteriaThey do produce a smell that will last for days.Keep your pets away while using ..Don’t turn them on without UV safety glasses they are strong and will damage your eyes.

Product: UVC with Ozone 25 wattFirst purchased 2022, 5 starsLast purchased 2025, 0 starsFrom 5 stars in 2022 to no stars in 2025.I thought I had received the wrong item because there was no discernable ozone coming from the bulb.In 20221 light bulb filled my small basement with ozone in a couple of hours.In 20251 light bulb produces no discernable ozone.When lamp with bulb is placed in a small box and covered with a towel, a gentle ozone smell is discernable in about 5 minutes, SERIOUSLY!These bulbs are now useless !

Worked well to disinfect and help fight mold and insects, lowers odors
