DARKBEAMUV Flashlight Black light UV Lights 365 Ultraviolet LED Blacklight Handheld Rechargeable Flashlights Pet Urine Detector For Dog/Cat Urine, Scorpion Hunting, Bed Bug, Dry Stains

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.

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.

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.

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.

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
