Review on 🔦 uvBeast V3 365nm Black Light UV Flashlight: High Definition Ultraviolet, Rechargeable 18650, High Power & Long Range - Professional Grade Beam for Commercial Use - USA Stock by Kevin Kimbrough

I have a lot of these 365nm LED UV lamps. This looks very professional and comes with lots of accessories and instructions. But no matter what people say about how bright it is, it's not as bright as a true competitor. I would compare it to FYRFLY C8 (not available on Revain). It's a smaller and more expensive light source, but it's also brighter with a narrower beam than this light source. There's nothing wrong with this flashlight and I'm wondering how you can add a third battery to the case, making it less likely to run out of power in the field. It's still very bright (in UV, not visible), just don't believe everything they say about UV performance. This flashlight comes with a charger (which I have not tested) and two 18650 batteries (which I have tested and which basically match the capacity listed on the batteries page). It also has an extension tube, as mentioned, so you can use a three-battery flashlight. It makes the light look pretty impressive, although I don't think I would try to impress anyone with it. It appears to be a quality light that is easy to order and quick to deliver. Made with quality parts and accessories. It's just not the brightest. Also, the beam is still pretty narrow, which might not be the best option for collecting rocks on the beach.
