What is the UV NM frequency rating of the flashlight? I hear there are different ratings and that it makes a difference. Is that true?

Our light is a 395 nM LED UV. If you were to go through the listings of the top selling UV lights for detecting pet urine you would see that most of them are 395 nM. If you want to see a breakdown of the UV wave frequency applications Wikipedia has an excellent article. We include the UV glasses because they help to filter the UV light at 395 nM. Regardless of the UV light you choose make sure to use high drain alkaline batteries because like a remote control car your more concerned about high performance than battery shelf life. Please feel free to contact us if you have any additional questions.

I'm not sure. I used it around the property on appx 15 mins I never noticed. it is a amazing flashlight !!! just be sure to turn it on at least once a weekfor a minute or so, son in law left his in a pack unused for a couple of months and the batteries swelled up and could not remove them. Mineis great though.

I got no idea, I'm sorry. The only thing I know is this flashlight is pretty good, I work as mechanic in a night shift and I use every day.

There is a performance gain by using the 18650 battery. I tried both battery options and found the 18650 to work the best. I have a couple other flashlights that uses the 18650's. I purchased a 12pk of the 6000mAh batteries and that is my recommendation. That last for ever. I hope this helps.

I would like to know too, it is odd how lumens are not mentioned for this flashlight.

Mine works beautifully! I would estimate the lumens to be closer to 1000, however, the kelvin rating is very close to 5000k (white). Most other flashlights put out at around 3000k to 4000k. This means the light is much more visible to the human eye. I just bought mine and ordered another as soon as I tried it out. I was blown away.

Great flashlight! But unfortunately it came with two, very lame, COUNTERFEIT UltraFire batteries. They say 3000 MAh, but are probably only 1000 MAh. This is also supported by the weight of the batteries. A normal 3000 MAH Lithium battery weighs in at 1.5-1.7 oz. These are only 0.5 oz. Also, I sent a picture of these batteries to UltraFire and they said that it is not theirs.

Mr. Cain, I agree with Sharkman, yours must be defective. I use my XL50 significantly more (especially right after I got it) than you, and I've been going on the supplied batteries for several weeks, and still daylight bright. Too bright in some situations in fact. My friend bought the XL100 over the weekend, and comparitavely they are about the same other than a slight tint difference. Where I prefer simplicity, he chooses enhanced function. For the money, there is no better light at 100 lumens IMHO.

Milliohm hours deals with longevity, and depending on the flashlight it won't affect brightness. Most flashlights won't allow the brightest levels when battery starts to get low. Also the quality of the batteries and charger had an impact. My boss had a crappy 3600 mAh battery that lasted half as long as my 2600mAh Tenergy, both 18650 style. I would say that the 18650's are a better option than two 123's, but some flashlights won't take the slightly larger 18650's.

I use Ultrafire (from China) and Panasonic (from Japan) in a number of flashlights. I have charged all of them at least 10 times each, and can't really tell any difference between them. They all charge within 12 hours, pretty slow, but hold the charge for a long time; I'm talking about many months if you're not using them. Hope this helps.

hi there, I bought 2 of these. Works very good, plenty of power for most jobs. As you can see in the left of the primary image, is the LED thing, in which you slide the battery. So you have to either use the drill, or the flashlight(if you have 1 battery). Personally not very impressed with the flashlight, not powerful at all. Recently bought a camp lamp(with 57 leds), from ebay for about 7-8$, it takes 3pc of AAA, and it works better, it is lighter, and you can hang it like a regular hanger. So don't rely on the flashlight..But the drill is awesome ! Got it for a deal here, was around 65$ with free standard shipping. hi there, I bought 2 of these.

Put it this way, in my opinion, there is NOT a better flashlight out there. Hope that helped.

I have not had this problem with my flashlight, it works just fine. Sorry to hear you are having a problem.

I would go with what the package specifies which is 180 lumens. The descriptions in Amazon are not always accurate. Regardless, a "difference" of 10 lumens in a flashlight isn't going to make much of a difference anyway.

This flashlight has a 275 degree spread without the use of the zoomed in feature. It will illuminate my whole front yard out to 100 ft LIKE IT IS DAYLIGHT in TOTAL DARKNESS. YES.Zoomed in it is around 3 degrees +/- on axis...Meaning 3 degrees above and below 90 degree angle= 6 degrees TOTAL @ FULL ZOOM...It looks light a "Light Saber" from Star Wars and it good for spotlighting a bear at 100 ft (pretty much JUST the bear, mind you, everything else is UN-illuminated) and good for 200 ft at full zoom. Really COOL! Eats batteries. Get the 2x 3.7 volt Lithium-Ion w/charger. Use it like a sniper (short bursts) and carry a spare...You'll be happy!

This is a UV light. It doesn't output white light, it's a "black light". You wouldn't use this for more then a few minutes at a time and it's definitely not for hiking or actually seeing in the dark. That being said, I have had the same batteries in it for about 8 months and it still runs strong, however its only used about once every 2 months for maybe 2-3 minutes.
