S3 365nm UV Flashlight with 3 LEDs, Powerful Blacklight Flashlights for Pet Urine Detection, Resin Curing, Rocks, Scorpion

Bought this and some cheaper adjustable beam lights. The shorter wavelength has a deep purple color and very little visible light. Fluoresces objects about the same as the cheaper lights with the longer wavelength and their beam zoomed all the way to be a square. This is a non-adjustable flood light. Battery life is excellent. Bought to check for hotel bedbugs, and how well the kids cleaned the bathrooms. So far has worked great. Also charges up glow in the dark things in seconds, finds carpet stains, finds mouse urine trails, and shows cool hidden patterns on some flowers.

This thing is intense. It will show you everything. Even things you may not want to see. While "testing" it to see how the quality was, we covered hands prints on our bedroom walls that have apparently been there for many years. It does do a great job revealing power marking and accidents.

Works great for finding cat urine spots on dark carpet. Lights up the affected area in a light green. Great product. Exactly what I was looking for though now I will probably get cleaning alot more then the carpet.

I have a collection of minerals from the Franklin mine in New Jersey, which is world renowned for glow-in-the-dark specimens. Some glow wonderfully under this light, but others that I know will glow under other lights will not under this one. I’m assuming that’s because different minerals require different wavelengths to give off photons. The light works great for detecting, old dried cat urine, and gross stains in hotel rooms. While exploring in my garden at night, I found a centipede that lit up like a firefly under this light.

Wow, my house in UV light! Looks like the upside down on Stranger Things: lot of creepy stuff everywhere! So this thing has the good wavelength of UV, shows more than the other wavelength, I am pretty sure. This Vaseline glass picture blew my mind when I lit it up!

Less functions than I needed.

Powerful and seemingly well made.

As a professional carpet cleaner, I'm very impressed with the intensity of the UV light from this flashlight for urine detection. Much more powerful than other lights I have used in the past.
