DARKBEAM B01 10W UV 365nm Blacklight Flashlight Wood's lamp Black Lights Portable Rechargeable Ultraviolet Handheld Scorpion for Pet Urine Detector Resin Curing

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.

The light is neatly packaged in a reusable case. Instructions are ok. The housing is durable metal and is well constructed. The rechargeable battery will need to be fully charged before use. The wavelength on the light is nearly invisible on non florescent objects. I have been using this light at work to locate leaks with UV dye additive. I would recommend and buy again.

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.

I bought this and the uvBeast New V3 365nm Mini at the same time and compared them side-by-side. The uvBeast simply plus into a USB-C cable to charge, and that is great, but that’s the only thing it has on this one (which uses a clunky and cheap external charger).There is a bright spot at the center of the beam on this flashlight, but the falloff is more gradual than the uvBeast, and it’s far easier to inspect a large area with the Darkbeam flashlight. And the center spot in this one is just as bright as the other, so there’s no compromise in working distance or detailed inspection.One other thing: whoever first said “ignorance is bliss” must have owned a UV flashlight. I got mine to look for stains from the cat, which I readily found, but, friends, my reasonably clean house looks like a dumpster in UV light. Be prepared.

Great Product !! As I learned after receiving it that it is a True Black Light , because it shines at 365NM ( Nanometers ) and Not 395NM . I Seriously have to be Careful NOT to Shine this at My Eye(s) because it does tend to Burn and Hurt afterwards . I'm Very Pleased with My 365NM TRUE Black Light :) !!!

This is my first ultraviolet flashlight so I have nothing to compare to but as far as I can tail this one works really well and is worth the money and it is way cheaper than other brands for the same thing

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.
