I ordered this product to be able to spot "accidents" by our elderly cat, but this isn't a real blacklight. It doesn't fluoresce on anything except reflective white items. It's going back.

I ordered this UV light both as a way of spotting where my 15 year old cat was piddling and also to check vaseline glass for uranium content. It works fine for spotting urine stains, but doesn't seem to work so well on glass. Maybe it was just the way I was using it, but it seems to only highlight specific spots on the glass rather than give it a nice, even, all-over glow that you need for photographing. I think the style of UV lights with the long tube would work better for that purpose than the flashlight style.

Still, it does do a great job of lighting up urine stains, so if that's what you're looking for then this would be a good choice.

A very handy tool for identifying those hard to see urine spots on the carpet! For those dog owners out there who believe their dog would never urinate on their carpet this light is indispensable! A well made sturdy product.

First, upon looking at the flashlight, it is really quick to determine there are only 3 leds in this product, not 9... Ok, I'm all for replacing 9 low-output LEDs with 3 high output ones, but the product also doesn't work as advertised, so this is just additional proof the product isn't the one in the description.. It even had a printed label on the back calling it a 9-led light.

The description of this product specifically describes itself as being 380nm longwave, not 395nm and that it will fluoresce urine, ID,s etc, better than other LED blacklights. I say the sellers are blatantly mistaken about their product (or their supplier radically changed it on them to a much cheaper product).

The light appears blue to the eye, and would not fluoresce many things. For reference I tested it against a 20w woods glass fluorescent lamp. Yes the tube is much higher output, much purer and broader-spectrum UV than I expect out of a LED, but I used it to prove the items in question would fluoresce in blacklight.

-20 dollar bill, the security strip glows green in blacklight, but not this light.
-Maryland state ID, bright green "Maryland" stamps all over it in black light, but not this light.
-My cat's litter box - urine spots glowed green, this light caused nothing to glow.
-CFL bulb, tube glows green in blacklight, but not this light.
-B vitamin complex in water, glowed STRONG green-yellow in blacklight, no glow in this light
-a drop of clear liquid laundry detergent - glowed purple-white in blacklight, looked clear in this light.

-My teeth, freshly brushed with whitening toothpased - glowed strong yellow-green in blacklight, only had a trace of orangish-red with this light that was mostly drowned out by the blue visible light (different color due to only higher-end UV?)

I got a mild reaction out of a bright "neon orange" plastic toy and white paper, but nothing nearly as strong as the woods glass tube which made both glow so bright it was hard to look at.

While I don't expect a LED blacklight to be as strong, or as broad spectrum as the woods glass, I *DO* expect it to at least light up the urine and ID since they specifically mention it in the description. I'd also have expected it to light up some of the "easy" targets like the detergent and B vitamins.

I can only conclude this is now a "mostly blue" LED flashlight, with a very small amount of barely-UV in it.

It's getting returned, as this product is clearly mis-advertised.

This product is not as advertised. There are only 3 LEDs, not 9 as advertised. The wavelength is not 380nm as it appears mostly blue and does very little to fluoresce items that should light up. I feel like I've been ripped off.

Ordered this light to try to find tomato bugs. The light worked, but I did not locate any tomato bugs. It was worth a shot...

The light came on time, arrived in good condition and was priced about right.
