لا يعمل وبه بعض الخدوش

UV Beast V3 365nm flashlight, Item arrived from the USA ahead of schedule and well packed I purchased for finding butterfly and moth larvae & pupae, you should purchase spare batteries as the torch uses the charge quite quickly.

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

In a separate review, I gave a glowing review to the $40 "Little Brother" version of this light. Well, the "Big Brother" is no less deserving! I've had it for about 9 months at this point, and have used it everywhere I go. As someone who collects stones (both raw and shaped), and who also loves UV-reactive things universally, this light opened up a whole new world for me. Prior to this, I owned a 385-395nm light, which I enjoyed...BUT, it has a lot of limitations. For one, being much closer to the visual range, it gives off a lot of visible light in the pink and purple hues, which overwhelm everything in its beam, and makes photographing the UV reaction next to impossible, as it overwhelms the camera lens. Second, there are a limited number of stones that react in that wavelength range (I've seen 2-3 dozen, give or take, so far). But at 365nm, BOTH of those issues are solved. There is still a small amount of bluish light visible, but very small compared to the higher wavelengths...so the visibility, details and ability to photograph are all IMMENSELY better. And the number of stones/minerals that react at that specific wavelength is EXPONENTIALLY greater--I have well over 100 different stones in my collection so far, and there are hundreds more...PLUS, all the stones that react at 385-395nm ALSO react at 365nm. So in every way, a 365nm light is hands-down the far better choice for those who love UV. After that, which light is best for you depends on what you plan to do with it. If your viewing of UV is generally limited to stuff in one room, or stuff within arm's reach, the "Little Brother" version would probably do just fine. But for me, I like POWER. I like the ability to take my light outside on hiking or mining trips, and spot UV-reactive stones at a distance. So with both my 385-395nm light and this one, I chose to go with the bigger, more powerful (and therefore, more expensive) version. But I haven't regretted that decision one bit in the 9 months since I bought it. The 2 batteries that come with the light are a unique size (not AA or AAA as many lesser lights tend to use), but they last a long time during constant use (4-6 hours on average), and are rechargeable. From empty, they do take a while to fully recharge, so I recommend buying an extra set of batteries (which is something I do with ANY and EVERY electronic device I own), so you can have 1 set to use while the other recharges, or to extend your usage time when away from places to charge. Two sets of batteries will last you most of the day--8 to 12 hours, depending on usage. The only downside is, the longer you use it, the hotter the grip gets from the batteries heating up, almost to the point of becoming uncomfortable to hold. But if you switch it off when not in use, and take a break every little bit, that shouldn't be a problem. You can also get the smaller version, which only requires 1 battery (which can be charged inside the light via a charging port in the side of the light body), and doesn't have anywhere near the heat output of the larger, more powerful light. So it all depends what you want out of your light. I prefer power, so I chose the larger light. But having bought the smaller one for 4 friends, all of whom absolutely LOVE it, you cannot go wrong with either light. But having seen and used more than a dozen different UV lights of all kinds and qualities, for me, UV Beast makes the best ones for the money. Yes, there are cheaper lights out there...but they also have more issues--power, flickering lights, go through batteries like candy, etc. So if you want a top-quality light that works well, is rechargeable, and provides you a choice between small & convenient, or large & powerful...UV Beast is my recommendation, every day of the week. And that sentiment is universally shared by everyone I have either bought the lights for, or who has bought one themselves based on my recommendations.
