DARKBEAMB01 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.

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.

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.

This works well and is bright enough to light up uv reactive uranium glass from a distance of about 6’ in daylight. It does a great job on fluorescent minerals too. I’m glad I chose the 365 because it detects items that are dim or unreactive under 395 wavelength. I’ll probably be getting another one.

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.

Received the item. Tried it initially, but it wasn't turning on. Charged the battery, tried it again, nothing. This device is nothing but garbage. Absolutely garbage. Do not buy.

This flashlight is the best cleaning tool I own. It will show you stains and grime in a whole new light. Stains show up in places you would never expect them to be.

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.

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.
