EIDEAL™ | UV & UVC Test Card & UV Intensity Test Card | 3-in-1 UV Test Card | UVA & UVC Light Identifying Card | UV Bulb & LED Intensity Reading Card | UV Dosage Indicator Card | UVB Tester

I had need of a way to tell if there was UV in a particular area and found this card--a simple, inexpensive, easy-to-have-handy device.I first tested it by exposing it to sunlight and it quickly showed there was UV radiation in the area. I then exposed it to an LED light bulb and there was no UV indicated--which is what I would expect from an LED light source.I found the exposure scale on the back to be particularly useful as it gives an idea of the amount of exposure over time and can be good when you need to know if something has received a minor or major dose of UV. This could range from exposure to sunlight to exposure to another source.Overall I find it very useful and am glad for my purchase.

Very excellent tool. For saltwater fish lighting, this is a must-have. It's rare that something inexpensive works as well as this does.

So I decided to make myself a environmental test kit. I have detectors to measure just about anything except light. Sure a light meter sort of works but a photospectrometer is what I want. My wife says 3 or 4 K is not in the budget this week so have to find another way.While not everything inclusive this inexpensive card shows the presence and strength of UVA and UVC light. You can see the strength difference from clear, overcast, and clouds, and even elevation changes. You can also read strength of man made UV, germinicidal lamps, welding, grow lamps.It opens up a lot of interesting information for its 10 buck price.

This UV test card will check the presence of UV A/B and measure its strength.It will also indicate the presence of UVC but cannot measure its strength.

Se activa muy rapido para poder medir la potencia o el tipo de longitud de onda UV

I returned the EIDEAL UV & UVC Test Card because it doesn’t actually measure UV strength—it just vaguely suggests that UV is present without providing any real information. It was received at their return warehouse on January 13, 2025, yet I still haven’t received my refund. Very disappointing.3.31.25 updateThe seller reached out to me promptly and issued the refund without any hassle. I’m updating this review to reflect the positive customer service experience

“Does x block UV?” Now you can answer the question yourself. I’ve checked various resin molds to see how uv translucent they are, compared the safety of different sunglasses and goggles, and figured out the relative brightness of different uv lights. Probably gonna get a couple more.

Cards are glued together and can't get to the back. Not what I ordered.
