DARKBEAM UV Flashlight 365nm Filtered Black Light Woods Lamps 20W 3 LEDs

意外と紫外線が強かったです。照射した物体からの反射光が眩しいので気をつけてください。いろいろ使えて便利です。ライトの代わりにもなりますが、バッテリーの消費が早いので気をつけてください。

HOW WELL DOES THIS LIGHT WORK? So you think you have a clean house, do you? Take a shine around your house and be ready to be surprised (shocked is more accurate). As tested with initial 4.18 volts this is a very bright UV flashlight and is demonstrating very adequate illumination as the charge wears down. In other words, it is a good UV light source that easily finds pet and other stains/markers. I tested the revealing qualities of this light in several areas of my house including a recently trimmed door in my closet. I found a world of change between typical room lighting and the light provided by this flashlight. (SEE PHOTOS) As a side note, we used another model flashlight for UV detection while on a cruise ship and found that they did a super stellar job of cleaning and laundering just about everything. Point being, this flashlight can also provide peace of mind in some instances. HICCUP - First flashlight I received did not work. Replacement arrived, and in case it matters to you, the advertised AC-120v to USB adapter (cube) was not provided in either flashlight kit. Like most people, I have many adapter cubes however I feel that the product listing or contents of the kit should be revised for the sake of accuracy. PUT INTO USE - Package received included nylon sheath, yellow glasses, USB-A to USB-C cable, and the flashlight with USB-C charging port. I plugged the provided charging cable into a wall outlet that also has USB-A charging ports which commonly provide DC-5v capabilities. I checked the battery with one of my multimeters to find that the DC-3.6v battery had overcharged to 4.18v. With all the news about Lithium batteries exploding cars, and the warnings on shipping boxes, I contacted the seller who responded same-day with a very reasonable reply (see end of this review). Other observations include noticing that the flashlight does get warm during use. Even the UV light emitted from the flashlight causes a warming sensation if shined directly on skin. NOT shining the UV light on anyone’s skin and especially NOT where directly or reflected into anyone’s eyes is important. UPDATE: See comment from seller regarding charging. FROM THE SELLER: Thank you for contacting us regarding the details of our product. We understand your concerns and we are glad to further explain. We have consulted with our technical department, and they have tested the product before it was introduced to the market. Regarding our B16 UV flashlight: The maximum voltage reaches up to 4.2V. When the battery is fully charged, if it continues to charge, the voltage will peak at approximately 4.25V and will not increase further. Therefore, the maximum voltage is essentially 4.2V. We recommend not charging overnight and disconnecting the battery once it is fully charged to ensure longer battery life and enhanced safety. We have made significant efforts to listen to our buyers' feedback and strive to provide better products. Thank you for your support. Best regards, Beam of DAKELI In summary, I like the flashlight and will likely add it to my travel kit or something similar. I’d also like to try it as a curing acceleration for plastic resins too so I’ll look for that kind of materials for experimentation. Thank you.

I bought this to charge glow in the dark discs for disc golf, it's super powerful and does an amazing job. Unfortunately I shone it in my house with the lights off ...I then spent an hour scrubbing walls because my house looked like a crime scene. The flashlight does almost too good of a job.

I tested the battery capacity after 1 month and It was 4098 mAh, so this is a real new battery. Only flaw is that it's not zoomable

UV 365nmのブラックライトは初めてですが、今まで見えなかった世界が見えるようになり、驚いています。例えば、新1万円札を照らすと、鮮やかに蛍光が浮かび上がり、発行時期によってなのか、可視光デザインは全く同じなのに、蛍光デザインは変更されていました。全く知りませんでした。銀行からおろしたてのお札なので偽札ではないでしょう。 なお、携帯ケースが付属しているのですが、やたら頑丈で出し入れしにくくかさばります。本体が丈夫なアルミ製なので先端ミラー部分だけを保護できるものがあればと思いました。
