    • Detects UV-C, but doesn't tell you power output UV-C.
This is good for detecting the presence of UV-C using the green fluorescent dye, but the purple photochromatic area responds to 320-400nm UVA/UVB (not UV-C) which your light source may not emit much of at all. Testing this with Philips TUV 4W FAM 4W (G4 T5) tubes, which are advertised to emit almost entirely 253.7nm UV-C, and only about 8% in the 320-400nm UVA/UVB reaction range of the purple dye, all according to the Phillips spec sheet, I get almost no reaction from the purple dye. The purple photochromatic dye obviously works in the 320-400nm UVA/UVB range though because I get a very dramatic immediate reaction in direct sunlight. So my conclusion is that this will tell you that you have UV-C, but it won't help you quantify the intensity of it. Thus light sources that are perfectly fine will appear to "fail" simply because their spectral power distribution curve is too narrowly spiked in the UV-C range and not wide enough to also produce a large enough amount of UV-A and UV-B. The only way to really test germicidal lamps though is with bacterial cultures because the germicidal function is not just the intensity of the light source, but also the exposure time and the "penetration" of the light into cavities on UV-C opaque surfaces, the amount of light reflected off of the inside of reflective boxes that actually reaches a surface, and other complicated real-world factors. That's the main problem with UV-C disinfection at the moment. A lot more testing is needed to determine what sort of sanitizer box/cabinet designs work and how well. ... show more

I bought this to test out a wand style UVC disinfecting light I purchased back in 2020 after COVID was raging, as well as an aquarium UVC light that I purchased to make a disinfection box for keys, phone, masks, etc. I later was wondering if they were actually UVC after looking for a box version that could disinfect several items at once. It was in those reviews I learnt about this UVC card. It works as advertised and is clear about how strong the UVC light is. My wand showed at weak to moderate. The 5 watt bulbs was moderate to high. I've included the type of box I bought at Target. I lined it with what I had left of the reflective aluminum insulation and some tin foil. Works just fine. The UVC aquarium light in it is an 8 inch 5 watt bulb. It doesn't seem to get hot but it does seem to put off an odour that is likely low ozone. This bulb can be found here: https://www.amazon.com/gp/product/B092QMDWGJ/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&th=1 ... show more

    • Great customer service
I really liked this product until it just stopped working about 1-2 months after i got it. I messaged the seller and they informed me that if left in the sun it will stop working. I hadn't known this and that's why it broke. They sent me a new one and I'm very pleased. Great customer service! THANKS! ... show more

    • Already helped my lizards!
Bought mainly to test sanitizing ability of a project I'm working on, but to benchmark it I tried my lizards' UV lamps — and found out that they had worn out and were only producing visible light! Fortunately I had spares ready, which this card does accurately detect as a UVA/B but not UVC source, and my lizards are happily soaking up the right kind of "sun" again. (At first I thought the card was taking a long time for the purple color to develop, but when I took it outside to try it out on sunlight, found out the 15 seconds the manufacturer recommends is a generous estimate. This thing is *not* subtle.) Would also be a good gadget for a science-oriented kid, for testing different materials' ability to block UV (glass, different clear plastics, ???), or UV levels under different conditions (weather, time of day, day of year, ???), especially since it's cheap enough to toss and replace if they have the idea to test sunblock and have any issue getting it to rinse clean (I have not tested whether that would happen, might do after using as intended though). ... show more

    • Great product...alerted me to no-UVC protection
Without knowing it, back in 2020, I had purchased a counterfiet UVC germicidal corn-cob LED bulb here on Amazon for $75. I used it for ~2 years thinking it was disinfecting masks, gloves and the occasional hotel room. Turns out it produces no UV light whatsoever and the only way I could have known that is with a product like this. It also turns out there is no shortage of flim-flam people out there willing to knowingly sell garbage but lie about its features and exploit people to make a buck. As an aside, in general, if you are in the US, I would NOT PURCHASE any germicidal UV light product here on Amazon. Amazon does not expend the resources necessary to prevent sellers from duping its customers with fakes. The Quantadose tool is an essential tool to help customers know if they are being duped. The UVC germicidal lamp product I ultimately found here in the US and liked is the "Cleanaire 15 in. Portable UV-C Disinfecting Work Light with Motion Sensors Adjustable Timer Alert Warning Function" which I found at HomeDepot for ~$100. ... show more

    • Easy to use. Does what it promises.
Good and cheap method to measure otherwise hard to separate UV-light of different wavelengths.

    • Very easy to use and verify UV exposure
I bought this little UV tester card because I was concerned about sunlight coming in through my windows potentially damaging/bleaching/discoloring items in my house (specifically my record collection). We recently upgraded the windows in our home, and we were assured the new windows had significant UV protection built-in. However, I would still get an uneasy feeling every time the afternoon summer sun would come blasting through the window and land on valuable things in the room. I would frequently close the shades just to make myself feel better. I decided to put myself at ease with this UV tester card. I was able to verify that my windows are only letting through a very small amount of UV light, and that makes me feel much better. ... show more
