B01 UV-365nm

This is the ultimate, dedicated, black light. It’s so effective, it has the strength to work in daylight. It’s so bright, and worth the money! The included battery is rechargeable. The battery charger is included, along with a canvas type flashlight holster that can be worn on a belt or inside a backpack or purse. The build has weight to it, and feels like a quality product. I’m excited about it. After I go to bed, I shine it all around my room just looking at how powerful the beam is. I checked my tomato plants with it. If you grow anything, you know backlight makes most of the pests glow so tomato worms are easier to find. This light is amazing. This is superior to my current black light which we ALWAYS use before bringing our luggage into any hotel room. I cannot say enough about this product. If I had known that it was this awesome, I wouldn’t have let it set in my cart for two years. Buy it. You won’t be disappointed.

I purchased this light specifically for curing Norland NOA61 cement so I could install tritium vials on some EDC gear. This light is surprisingly nice and is super bright. The light includes a rechargeable battery and a charger, which is a nice addition. I found that this flashlight works much better than my cheaper UV flashlight for looking at currency, rocks/minerals, pet stains, etc. If you’re looking for a great UV light at a good price, this is it.

Didn't work out of the pack. I have a couple UV flashlights at this point, this one is DOA. Maybe I got a lemon, I don't know. The beam was weak at making stuff glow, so I inspected closer shining it on paper near the light. It would dim and then turn off completely just holding it for a few seconds. I suspect something is up with the soldering joints in there or something similar. Probably I will try to take it apart and see if I can fix it, but out of the pack it didn't work. It did come with a neat little battery charger and a battery that both seem to work fine, but the light itself is a dud. Wishing other's better luck with theirs but they could probably QC these a little better. Update before this posts... for those with the skill. I took apart the button after testing it to deem it the culprit. I put a little solder joint between the spring and battery contact cup, reassembled, and it's working like a champ now. Not updating the ranking because this should never be a problem. A flashlight button should just work.

Works as expected. I used the charger once and it appears to do it's job though rather slow. The light itself has been fine. It's really only used to charge glow in the dark books and stickers. I have no way to measure the wavelength but it's substantially different than the 405nm I use for curing 3d printer resin.

Hello, At first I was let down. The flashlight did not work, even with putting in a different brand of battery and fully charging the supplied battery. Then, I twisted the flashlight and it would work, but not all the time. The flashlight would go off, even when just moving it around. The light would be dim and sometimes bright. I would have to twist the body to get it to work almost every time I tested it. What a let down, for it did not work as expected. Eventually, I took off the top part (screwed on) and placed a brand new one cent piece to be the contact point between the POSITIVE terminal of the battery and the spring. Works great now ! If it were not for the aforementioned problem, I would have given it 5 stars. I may purchase again, since I know a quick fix.

It came with a battery charger and a case which was nice. It does a good job on fluorescent minerals.

365nm blacklight is very interesting. It makes everything look horrible, dirty and peculiar colors. It really brings out details you can't normally see compared to ~405nm purple blacklights. 5 stars for being awesome! One interesting phenomenon is that scorpions glow brightly with this light, even weeks after you kill them. At 405nm, they stop glowing strongly after a couple days of being dead. Consequently, if you use this light for killing scorpions, you need to bury the corpses so you don't see them again on subsequent hunting sessions. Unfortunately, I must deduct 1 star because the seller's description of being a 10W light source is very inaccurate. With a fully charged battery, it draws only 750mA, and at lower voltages the current drops even lower. In other words, this is at most, a 3 Watt flashlight and expect less since it lacks active power regulation. I cannot possibly expect the battery to actually be a 3400mAh cell given this type of gross product overrating. The battery lacks overcharge/discharge/short circuit protection. This isn't claimed in the description, so I don't fault the vendor, but be mindful that this battery isn't something you should recharge if you ever let it drop below 2V.

Now this is powerful and ultra strong glow, too bright on many objects. But you can see dust, debris, even green glow from many plastic (the 365nm wavelength and visible light filter really helps). Big rechargeable battery included. I didn’t see a lot of difference between the two wavelength settings, it’s there but subtle. The light filter has the most increase in ability. The only negative is lack of focusing, it’s medium tight beam only, but this is fine for most uses. That’s missing on the B01. But don’t expect to see urine with this or any other UV light, that doesn’t glow unless dry despite universal internet hype—and far dimmer that the whitening and dyes in many papers paints and clothes. It can see cat dander and scootch and sometimes barf as the cat food we use glow a bit though. Also a lot of other claims are myths too I see plenty of spots on bedding for example, more on older ones but no difference between clean and dirty. So I think some of that is fading or detergent residue.

The light is so dim and as a result it barely radiates anything. Please don’t believe the others’ lies that just because it’s dim it can still radiate fluorescent details. No it does not. When I first turned it on i thought it wasn’t even on as it was so dim.
