DARKBEAM UV Flashlight 365nm Black Light, Mini & Powerful Woods Lamp USB -C LED Rechargeable, Blacklight Flashlights Portable Pet Cat Urine Detector - Rock, Fluorescent Detection, Resin Curing

This UV flashlight works well for basic use. It’s not extremely powerful, but it does a good job of showing what you need to see. It’s small, easy to carry, and very convenient to use. The battery does run down fairly fast, but it charges with USB-C, which makes it easy to recharge. Overall, it’s a handy little blacklight.

I bought this because it was sized right (fits in pocket) and was also priced right. It's a great addition to my rockhounding tools.

This DARKBEAM flashlight is great for viewing lots of things, but my favorite is viewing Ooperlite stones. The 365 nm really makes the fluorescence of the stones stand out. The light quality is great!

with this I can see where my pigmentation marks are that doesn't show up yet on my face. Not as good as a scan, but I can see where some problem spots are and concentrate treatments on that area. Be careful not to shine in the eye. It's a very bright light and could damage them. After using this every once in a while over the past year, I can tell there is improvements. It's a slow process when you've tanned religiously as gen x gal. It's still running on the original battery...and you can also use it to see sprays of urine. I guess helpful for those who clean bathrooms. Good value, nice compact size, great price, --it works.

Battery life is good charges quickly its great for the price and works great for my use cases its bright and pretty durable this is the uv model that looks slightly more blue which is exactly what I needed

I had bought this to cure Mini Verse resin items. It cures them very quickly and efficiently. The battery on one charge can last quite a while. It's very durable with it being metal.

Works great.

Awesome! Very dark, very invisible until the beam falls across something that fluoresces. This is what I have been missing, when I was using 395nm led lights! I have attached a couple photos that I snapped with a slightly larger version of this light. You sure can’t shoot pictures like this with a 395nm LED!!! You need 365nm! If you like blacklight stuff, this will make you happy! Do you want to find out how badly your bathroom looks like a CRIME SCENE???😝 Then get this! You will see incredibly more stuff with this light! If you use professional fluorescent paint, you probably already know that you NEED something which generates 365nm (or lower), as there is an INCREDIBLE difference in the results you get from the paint when exposing it to the UVA range that it was made for! (Think Wildfire paint. With 395nm, it will be lack luster, muted and sad. But, hit it with 365nm, and it will “BLOW YOUR MIND WITH INTENSITY”!!) You need to know that cheap LED lights made with the common 395nm LED absolutely are UVA spectrum lights, but the UVA range “ends” at 400nm!!! So, 405nm is just “blue” light. That is important, because 395nm UVA LEDs are very close to blue, and that means they produce more “unwanted” light, but still will fluoresce some materials. Both kinds of diodes have their uses. My eventual hope is to buy a high quality, affordable 365nm LED light bar, or stage flood! I know they are available, but I can’t afford them yet. 😁

エアコンのガス漏れ部分を確認したくて購入。 蛍光剤入りのエアコンOILを入れてからしばらく経って確認。 高圧側のコンプレッサー接合配管のゴム部分から漏れてました。 しっかりと蛍光剤の確認も行え、電池では無くUSB充電タイプなので使い勝手が良いです。 難点があるとすれば点灯時間が長いと本体が熱くなるのでそこだけ注意です。

USBCで充電でき電池不要。 見えない汚れがはっきり見える。 UVレジン硬化に使える。 小型で携帯性が良い。 コスパが良い。

頭部をクルクルと回すとLED部が外れるのですが・・・ バッテリーは18650よりも細身のリチウムイオンバッテリー。 しかもリード線はハンダ付けでした。（まあ、問題は少ないと思いますけど） で、2度頭部を外したらリード線が切断して点灯せず。 再びバラして切れた部分をハンダ付けして復活。 もう少しバッテリー交換が簡単に出来るとよいですね。 18650バッテリーならば、更に良かったか？ 最近のバッテリーは質も上がってきたようなので長期にわたり使用できることを期待しましょう。 万一、バッテリー交換した際には再度アップしますね。 最後になりましたが、光量は全く問題なく十分な光量があります。 コスパは高いです。

It's strong enough to cure solder mask quickly, feels and looks high quality and has a badass name. Makes you think you got something "premium" in your arsenal.

光源は強く、蛍光探傷には反応しますけど札の特定部位には反応しないです。周波数の違いと思います。
