I'm very happy with this purchase.I bought this so that I could see if there was any stains left in the carpet due to my dogs urinating on it. I have a steam-vac carpet cleaner and wanted to make sure it was doing its job.
There are a bunch of different UV / black-light flashlights out there, but this one seemed to have the most LED's for the price. And it takes AA batteries instead of AAA's. So it should be a lot brighter, and the batteries should last longer than other flashlights out there.
My results: The flashlight itself is very solid. It's made of metal. It is very bright and does exactly what I want. The beam is focused well. It showed me stains in the carpeting and the couch that I didn't know were there. It's so bright that I didn't have to even make the room completely dark. In fact, you can use this with your house's lights on, although it won't work as well.
So it does show me how well my steam-vac carpet cleaner works. I expected that. What surprised me was that it also shows me how well my regular vacuum cleaner works. I see little dots of bright stuff all over my carpet. That's the dirt and lint that the vacuum cleaner missed. Time to get a better vacuum cleaner.
The only negative thing I'll say about it is that once you get this thing, you're going to go from room to room in your place looking at everything. And you're going to find everything! It will surprise you. In the end, you may become a lot less happy with your carpeting and furniture, to the point of wanting to go out and buy new ones. This inexpensive little flashlight "toy" may end up costing you thousands of dollars.

This light can be opened from the bottom or the top to insert batteries.DO NOT OPEN THIS LIGHT FROM THE TOP!
It is constructed in such a way that the wires spin around and snap apart as you unscrew the head.
The seller should include instructions or the makers should seal the top so it cannot be opened.
I had no problem inserting the three AA batteries as some other did but my light never came on.
Broken wires in the flash light head.
The casing is solid enough but the inner design is flawed.
Light like this are usually reliable.
I would recommend anyone who buys this light to remember NOT TO OPEN IT FROM THE HEAD like most flash lights, batteries can only be inserted from the bottom.
Shipping was fine no problems.
Honest reviews on LEDwholesalers 395 nM 51 UV Ultraviolet LED flashlight Blacklight 3
I ordered one of these through Amazon from LEDwholesalers on January 5, 2011 for exposing pet urine spots, and it worked (and continues to work) great. Based on the strong performance of the original, I recently ordered an additional one (also through Amazon/LEDwholesalers) on November 6, 2011, and it is terrible. I don't know if they switched to cheaper LEDs, or what but the old & new models are obviously COMPLETELY different when using them side-by-side. The old one works fine, with the light energy centered strongly in the UV spectrum. The new one has an unacceptable amount of the light energy in the visible spectrum, essentially a regular flashlight with a purple tinge ineffectual for exposing pet urine & other stains. I'm keeping the old one, and sadly, returning the new one to search for some other brand that performs well. By the way, if you get ANY of these sorts of UV lights, please be sure to buy a pair of yellow protective glasses they protect your eyes AND make stains more visible. The ones from LEDwholesalers (UV Protecting Adjustable Safety Glasses Yellow Tint,7821) work very well, and are reasonably priced.Find helpful customer reviews and review ratings for LEDwholesalers 395 nM 51 UV Ultraviolet LED flashlight Blacklight 3
By the time I arrive in Mexico (I live there) and actually hunt wandering scorpions I'm afraid the time limit for opinions will have elapsed.1. The batteryless flashlight was heavier than I expected. It is made of milled aluminum similar to a MagLite.
2. I took note of the warnings on this board to open the end opposite the bulb to insert batteries, and so I did.
3. Inside I found a removable white plastic "cartridge" that slipped out in order to load three AA batteries into.
4. Both the orientation of the cartridge to the lamp and the polarity of batteries to cartridge were clearly marked.
5. I used Duracell AA batteries and the cartridge slipped back into the lamp with no rubbing.
6. The threads on the cap are similar to my MagLite so a coating of petroleum jelly would make the lamp moisture resistant.
7. The switch is a press on and off with rubber cap just like a MagLite
8. The body of the map is knurled just like a MagLite and also black in color, probably hard anodized.
9. Qualifying the "intensity" of the beam is subjective so I'll make a few general comments below:
Most of the energy from a UV source is invisible. The best way to see what the lamp is capable of is to illuminate an object that fluoresces. The darker the space the more UV ontrast there will be and the brighter the objects can glow. For my 64 year old eyes the visible light emmitted from this lamp would not be enough to illuminate strange paths, rocky terrain, etc. in order to walk over. I would need a flashlight.
There seems to be plenty of UV light generated to do what I am going to ask this lamp to do. I don't need to see every grain of sand or twig around a scorpion, I want the aracnid to glow like a firefly, so I can light it up with a conventional lamp and then then take care of the unwanted visitor. Part of the misconception of UV illumination is that folks seem to feel that the light has to flood the target in a bright blue light. It takes a lot of energy to do that. UV light rays can scatter like crazy leaving the target area dark but a scorpion will glow like a Christmas tree bulb. Indeed it is this contrast that aids in finding them.
Now the trick is to see just how durable and long-lived this UV lamp is going to be.
