I use a UV light at work for quality checks. The light they've provided me is not very bright and there's a poor connection in it somewhere. This light is much brighter and seems to be considerably more sturdy. I haven't used it yet at work, but just turning it on at home I could see the difference. I think this will work out great. I may add another star after I check it out at work.

For the people who have had flickering problems, I too have had this problem. In order to resolve this I had to unscrew the top section. Inside there will be a ring with 2 small indentations. this ring is removable. Take it out then take out the led bulb circuit. The way this circuit works, the "+" comes in through the center and the "-" or ground is along the outer rim. If the ring with the indentations doesn't make solid contact there ends up being an open in the circuit and the light flickers. There is a thin coating around the edge of the rim where the green surface stops and becomes bare metal. I was able to scrape away some of this coating using just my fingernail. Scraping away some of the coating on the bare metal will allow the ring to make better contact and close the circuit.

Put the led circuit back in place and screw the ring back on making sure the indentations are facing out. You may need a pair of snap ring pliers to remove and replace the ring and to ensure that the ring is in securely.

I performed this process on the 2 flashlights that I purchased and both now work perfectly.

I hope this helps anyone who is having this problem and is willing to attempt to fix it on their own.

The kids and I love this inexpensive little light. Just be warned when you go hunting around in the dark, you will find lots of things that 'glow' under the UV light, that a regular light would miss. Lots of household products and materials, specks of litter in the carpet and in dusty corners and body fluids all glow. You may find your bathroom is less clean than you hoped. Happy Hunting!

We bought this UV light to use when Scorpion hunting in Arizona. It works well for that and under the UV light they fluoresce and are very obvious. We also used this light to identify places where the pets had an accident in the house. If we found out quickly and were able to clean it well, it would barely show, but a spot we didn't clean so well glowed. In a way, this light is frustrating because it shows you places you thought were clean but now realize could use more work. Items on the carpet really stand out. Be prepared to clean your carpets if you have indoor pets.

This isn't the most powerful of lights, to get it to work well we had to turn off all the lights and look around in the dark. Then things would really show up. If you have too much "white" light at all, it won't be powerful enough to overcome it. In a room with 100 watt table lamps it would cause things to glow a 2-3 feet away but then fade out due to the white light.

We tested with money, credit cards and ID's and it worked very well for showing the markers on those. I also powered the light with rechargeable batteries and they worked fine with those. Some lights have an issue with rechargeable batteries due to slight voltage differences.

4 Stars for working well; it could be more powerful but for the price it's a great value.

Honest reviews on UV Blacklight Flashlight By Ultra Light

This is the second light I have ordered and so far both lights have broken within the first week. I would not recommend this item, spend the extra three dollars for one of the other lights and save your self time and money. Amazon please remove this seller!

This products works as advertised, and works well. A couple of observations:

1. This is a UV light. The human eye cannot see UV. Therefore, this light does not have nearly the optical brilliance of a conventional flashlight in its class (i.e., 9-LED compact light powered by three AAAs), as much of its output is in wavelengths too short for the human eye to perceive as light. But the energy *is* there. If you doubt me, go to a reasonably dark room and shine this light on a glow-in-the-dark object from, say, fifteen feet away. You will see it light up. If you shine the light on a white wall, and look at the wall for a couple seconds and then shut your eyes, you will see an afterimage even though the light does not *appear* bright enough. That's from the UV hitting your retina.

2. The light is bright enough for most applications. If you need more UV light, just get three and then rubber-band them together. That should be all the UV light you would ever need, or want, for conventional consumer or prosumer purposes. You don't *want* too much of this light. UV light is not good for your eyes. The danger is that, because this light doesn't appear "bright," your pupils do not constrict when exposed to it, leaving your eyes dialated and your retinas flooded with UV. This is why your optometrist gives you a pair of UV-proof sunglasses or covers for the lenses of your glasses after dialating your pupils during an exam: so when you walk outside, you don't get hit with damaging levels of UV from sunlight as your pupils are unable to contract.
