uvBeast V3 365nm Black Light UV Flashlight – High Definition Ultraviolet - HIgh Power and Long Range Professional Grade Beam Best for Professional/Commercial Use – USA Stock

all good

It came scratched and the on/off button wasn’t working properly and stopped working after one week. Not the original UVBeast

Insanely intense. Think of those LED Mag-lite's in terms of radiation intensity, but in the 365nm UV range. Compared to the cheaper (1/3-1/2 the cost) 385nm units this light has a very intense center spot-like beam (versus the more narrow-flood of a standard UV flashlight) and really brings out the contrast of any flourescent materials by being much less visible in the background.One thing I noted: this flashlight gets very hot after a few minutes, even with that decent heat sink designed into the head. Checking it with a photospectrometer, I found that it irradiates a massive 820 µMols of iR (think REALLY bright spotlight, but in the infrared range) at 12"--if this was visible spectrum, it would measure approximately 47,000lux. You can feel it, a very distinct beam of warmth when shining the light on the inside of your wrist from a foot away. So if your application needs UV but must remain at cold temperatures at close distances, this may not be the flashlight for you.Aside from the heat issue, this is a well-built and very intense UV flashlight. I'm shining it on everything. Even in a normal day-lit indoor room I can still see fluorescence in objects. This uses removeable lithium ion (18650 button-head) batteries. The unit includes two batteries, a charger and an extension tube so a third 18650 (not included) battery can be added.Interestingly, in the interest of answering "is it any brighter with the third battery installed" I ran the spectrometer several times each with two and three batteries. I noted a REDUCTION in intensity by about 3% when running on 3 batteries (guessing there's some inefficiency in voltage conversion from 11.1v down the the unit's 7.4v operating voltage). So you're trading another 50% runtime for a very slight (not noticeable to the eye) drop in illumination intensity.Highly recommended if you can afford its price tag. This is one tick shy of a full lab-grade unit at a quarter the price.

I'm a newbie to Rockhounding, and after buying the 'wrong' torch, decided to pay more for a quality bit of kit. 'The Beast' is certainly that! The results speak for themselves.For me the downside is that it also highlights the creepie crawlers! Yuk! Happily, it gives a white light, and also highlights the fluorescent rocks, which was the purpose of buying it. I'm satisfied!I can recommend The Beast! Easy to recharge and easy to use. Not too heavy for a long rockhounding session at night, AND it works during the day under the right circumstances. I have not tried using it in bright sunlight but it works in my garage and cloudy days.

Je retire une étoile car c'est quand même un peu cher. A la limite pour ce prix ils pourraient intégrer une bonne paire de lunette de protection.Mais la qualité est là. La lampe est puissante, le spectre UV semble propre. Il y a une belle projection.Je m'en sers notamment pour la fluorescence des minéraux.Evidemment, ça marche mieux en condition obscure ! Ce n'est pas une toche led classique pour éclairer de larges zones, et ce n'est pas son rôle.Je suis un peu mitigé sur le pas de vis du corps de la lampe, à voir à l'usage.En tous cas en terme de construction et de puissance, c'est parfait.Il y a une "rallonge" avec des joins pour permettre de rajouter une troisième batterie pour une utilisation prolongée. C'est assez apprécié pour une utilisation sur le terrain (dehors, dans une grotte).Je remarque quand même que ça fait mal aux yeux, ce qui n'est pas étonnant, le spectre étant à 365nm. Je ne saurais trop vous conseiller d'investir dans une bonne paire de lunettes anti UV dédiée afin de ne pas vous abimer les yeux. Méfiez vous des UV, ils sont puissants et ils sont réfléchis par les surfaces blanches (des feuilles de papiers par exemple).Bref, la torche est, je trouve, top !

Mükemmel ötesi bir ürün, kesinlikle tavsiye ederim.

Muy buen producto y larga duración de sus baterias
