Review: Awesome light - Note this is a UV light and barely produces any visible light. But when pointed at anything which is UV reactive it causes them to grow brightly. The flashlight is made of heavy duty materials. The three 18650 batteries which came with the Alone Fire brand on them seem of good quality. Charging them takes a long time, but I prefer that to fast charging. The button is good quality and sensitivity and has functioned many times without failure. There is no 1/4 inch hole for attaching to a tripod. It has only 2 brightness levels and toggles from off to bright to low. Caution: Do not point directly into your eyes. It will physically hurt and may cause damage to the eyes. CAUTION: Do not use to check you wife's work after she cleans a room ;) It does provide a good method for checking you work when cleaning up pet "fluids" off of couches and carpets. Lint in general with show some reflected light, Carpets will also show reflections similar to lint but with several different colors. It was fun to take to my local Rock Shop and see which stones and crystals glowed. Works great to charge glow in the dark paint and tape, which glow very bright under the UV. When shined on your skin it will feel warm especially up close. It does penetrate the skin a bit and exposes bruises and makes scars much easier to see. Some bruises which are barely visible will be easily visible under this light. It does not shine very far but I think that is the nature of UV light. But up to 20 feet away only the brightest of UV reactive colors will be visible.
Review: Very effective UV light - First off….. do NOT get this if you’re OCD about being clean, or your spaces have to be clean. This up lamp shows things….. you may not want to see. Ancient stains show, dust is amazingly clearly seen, splashes of liquids you thought you scrubbed immaculately clean, this light will show. This UV light is filtered, which means it won’t seem bright until it hits a UV reactive object or substance. DO NOT look into the active emitters, you could cause eye damage, do not play with kitty with this light, do NOT EVER let your children touch this light. From what I see that this light emits is very high UVA energy. Now that all my warnings have been said. This is a pretty solidly built light. Tight and smooth threadings on the body pieces, comfortable to hold and very simple operation. One click from off is high power, one click while on goes into low power, another click turns it off. 4 quad element emitters shine through a filtered lens that allows it to emit just as near or on 365nm wavelength UV. Or in the UVA spectrum. This will not sanitize fully surfaces it shines on, and it’s not intended to do such a thing. However what it will do is illuminate yooperlite stone, white objects, and…….. it does very well, almost too well at showing pet urine stains, dust, and chemicals on surfaces that react to UV, I haven’t thank god had a scorpion near me to see how well they show up, and I don’t want to *shudder* but this would do the trick. The beam can get hot on the skin and the emitter head can get warm during high power operation. But that’s normal. Haven’t had it long enough to gauge charge levels, and how long it can run on a charge. For its price tho, it’s a very good unit. Too good in some cases. Simple, effective, easy to use. A excellent value in my opinion and time will tell on its durability and longevity which I hope is very long. I do wonder who makes the emitters tho.

### ⭐⭐⭐⭐⭐ Great little flashlight!!!
*by P***N on February 18, 2025*

Great high power low level black light. Works great for identifying and finding certain types of rocks and gemstones. Much brighter and stronger than previous ones. I’ve bought by other brands. It does get very hot so you can only use it for short periods of time between letting it cool off. It’s very compact and stout slightly heavier than you would think it would be, but it must have a large rechargeable battery in it. Charges with a USB-C cord, which is convenient if this one wears, I would happily buy another.
