Tragbare UV-Lampe zur Hautuntersuchung bei Haustieren

Well shows the hair damaged by fungus, its glow is different from ordinary dust, thank you very much.

365 UV Wood Lamp for Pet Fungus Detection

The product exceeded expectations.
Sturdy pen with material that seems durable (let's see in the long term). At the top end, there is a magnetic cap with a USB port for recharging the pen. At the very bottom end, there is the actual light.
I tested it in a dark environment and the light is very powerful. The pen came with a charge.
For those who will use it as a veterinary tool, I haven't tested it yet, but I imagine it will work.

compact flashlight, has a black lens. found different stains on the carpet. nothing extra was shining on the cat. we'll go to the vet and check.

I loved it! Very compact, charges via USB. But you need to keep pressing to emit the light.
