Question: I want to make sure that I'm ordering UV lights made in the US, not China.....please advise....thanks.
Document: I ordered this flashlight and my wife then ordered two from UV Sight, because she didn't want to wait on the shipping. Not only are the UV Sight flashlights much brighter (I'd say 3-5x brighter), they throw a wider beam and they come with 3 AAA batteries. I had to buy CR123A batteries for this Ultrafire, which doubled the price of my purchase. The UV Sight lights are easier to operate and quite a bit smaller. The only thing better about the Ultrafire is the nice handstrap.
This will spot protein stains on walls or carpet, bedding from 15+ feet away no problem! (CSI anyone) Be sure you have a good pair of yellow UV blocking eyeglasses because this torch puts ALOT of UV rays out (ouch) and a good amount of purple visible light for those that want a very pure UV light, this is not it.My son has some glow-in-the-dark clothes and this light makes them light up like they are ON FIRE!
So...this UV flashlight is simply bad. Not due to the structure/design of it (it's actually very well made, seems very nice in regards to that), but due to it's "UV" bulb.I'm not even convinced that this is putting out UV light, as nothing has that 'blacklight glow" to it. The light coming from this bulb is a very bright shade of blue(450nm-465nm), and has no purple to it at all(425nm-400nm).
It is handy for finding things like bits of glass if you have an accident with a glass item. Also works for tracking pet pee (dried). I'm sure it has many other uses.
Its very bright purple, and seconds as a flashlight. I bought it for Halloween to follow the kids around, with some 'glowing' stickers on them, I could easily light them up from a distance with this light. Maybe it just needs less of the visible light range. For the price I'm OK with it, I have no other comparison to other lights to know what is normal with these.
People saying this is dim must be looking for a violet light, this is a TRUE uv Black light bulb with VERY LITTLE light emitted in the visible spectrum. This is good because visible light will make the objects fluoresced under visible light appear DIMMER because it is washed out.Ignore reviewers who say this is dim, unless you are looking for something that is &#34;bright&#34; to your eye. This little light is DANGEROUS, as all true UV lights.
Ok. I'm not sure if it was a good idea to get this. Here's why.Charged battery and walked around house at night with the black light. My kids toilet was all marked up with bad aimers. Asked the boys if they were lifting lid. Yes....  Then turned on the black light. Busted. Ha.We got a puppy several months ago and it would potty when excited. We thought it was all cleaned up.
I got this because my 3 AAA UV flashlight just wasnt up to par. I bought this one and WOW! It is soooo bright!!! If you want a UV light for currency detection, this is NOT the light you want. However if you want a UV light for pet stains or in my case, searching out scorpions in and around my home in Arizona...this light is it!
This UV Flashlight is just what I needed for tracking wounded deer. I ordered extra batteries and installed, used during deer season and Bam Awesome! Less than 10 min. later found the deer! Best money I ever spent. Quick delivery and well made!
I'll update this post after after a better test. I'm gonna try to figure out exactly what LED emitter is in it.Overall I'm quite pleased with this inexpensive UV light. I do not feel that i have to baby it. If it survives for a year in my truck, and i think it will, I will feel I got more than my money's worth.One further note. UltraFIre brand batteries are crap. Don't ever buy them. Especially 18650's.
