LUMINTOP Tool AAA Waterproof Flashlight, 130 Lumens, IPX-8, TIR Lens, 3 Output Modes, Memory Function, Battery Powered

Easy to figure out where the battery goes (unscrew either end, replace battery, tighten back up) and easy to use without needless strobe or blink modes. The solitary "clicky" switch on the tail controls three brightness levels (that correlate inversely to battery life) and that's it.The LED/head assembly outputs a narrow flood of light with a wide hotspot through a textured plastic lens. The hotspot is not tightly focused, so this light is best for close-up tasks or giving you some light in your immediate vicinity. Although the optical results aren't top notch, given this light's low cost, I find the beam quality acceptable and certainly usable. It's not perfectly smooth and uniform, but it's far from being bad enough to distract from your task.It's a good value for its performance, especially if you prefer having a real thumb switch instead of having to twist the head. And if you want, you CAN use it as a twist-the-head type of light; just leave the switch on and twist away. Of course, the bigger advantage of that setup is that you can loosen the head (or tail, or both) slightly and it will "lock out" the flashlight from turning on with an accidental jab at the tail switch.Low mode is just bright enough for finding the keyhole on your door or walking to the bathroom at night while trying not to wake your partner. It can also run for hour after in low mode, so it's your friend in a power failure (that's a good use for the included diffuser cap).Medium mode is a good general purpose mode for looking inside a computer case or some piece of equipment at work. Also fine for walking around outside at night without falling into a hole or something. And medium mode with the diffuser cap gives you a nice little personal camping lantern for your tent.High mode, even though the light doesn't reach or "throw" very far due to its floodlight-like optics, could be useful for finding your bearings in a large room, or even outdoors, should the lights go out. The problem with high mode is that the battery drains FAST, and the light becomes notably warm within a few minutes. If it begins to overheat, it dials back on the output to protect itself. This tells me that the light isn't really meant to be used on high mode except as needed temporarily. This is very common behavior with the majority of small inexpensive flashlights though, so I'm not going to knock points off this particular light for it.What I like best about this light is how it's essentially a miniature version of any number of larger aluminum LED flashlights, complete with pushbutton switch and multiple brightness levels. This one just happens to fit on a keychain and uses one little AAA battery. Other goodies like the diffuser cap and the pocket/hat clip are icing on the cake.All in all, not bad as long as you don't expect long distance lighting or incredible battery life from one AAA cell.

I first saw LuminTop Tool reviewed on the Living Surviving channel on YT several years ago. I immediately purchased the black aluminum AAA version, then after a year, I sprung for the fancy copper AAA version, which BTW is a lot heavier and has spent most of its life sitting on my desk for infrequent use. The black aluminum Tool was my EDC's for a long time, but the copper one was just too heavy in the pocket. Both of the pocket clips broke within a few months of ownership, but since they live in my pocket, it didn't matter that much to me. I bought 2 rechargeable Duracell AAA batteries for them which I charge infrequently.The Tools give enough light at 110 lumens to be useful in most normal situations like night walks and looking for things that have fallen on the floor, however, for my work, I use the much smaller Rovy Von A8 650 lumen EDC which is MUCH smaller than the Tool with several more features. I often hold small flashlights in my mouth when working on and in guitars at my shop and the Rovy Von is just much smaller and easier to work with, plus it throws MUCH more light at the expense of having a non-replaceable battery (unlike the Tool battery which is easily replaceable).SUMMARY; The LuminTop Tool is a good reliable EDC for use around the house and maybe for camping. It is not good for working on your car or where strong light is needed. If your eyes are old and need a decent work light, the Tool prolly won't cut it, but the batteries are replaceable and the Tool is definitely tough. The copper version looks great but is very pocket heavy. The pocket clips break way to easily. The Tool is a good all-around EDC, but it's not good in all situations as it rolls off off things and its lower lumen output is not a redeeming feature.

Not rec'd under the Vine program, I paid for this. I've had on my keychains, for probably 10 years, some useful--but dim--Fenix E05 AAA flashlights, probably the best at the time, which used a single AAA battery, turned on/off solely by rotating the head, and had only a single luminosity, no choices. I was so surprised when I turned on this Lumentop at the advance in lumens due to advances in leds (can't blame Fenix for that--I've always found their other led flashlights to be excellent) plus the use here of a TIR optic lens. "A smooth globe of white Light", per the description above, is accurate. But this Lumentop is a great improvement not only in brightness & imaging, but in shaft design for tiny flashlights as well. The middle of the shaft is narrower than are the ends, providing a much firmer grip, making it more difficult to drop in the dark. And there is a button on the rear which provides access to three different luminosities--I use the middle one most of the time--with memory that starts up where you left off. And NO STROBE! (Will wonders never cease?) I expected pushing the button with one hand to be awkward, but when you grasp the enclosed carabiner behind the button, the keys drop down into the grip of your hand, making pushing the button with your thumb easy. A terrific design, a fantastic device, v. pleased with my purchase. Highly recommended for KEYCHAIN use: fits easily into a pocket with lots of keys, as it is smaller than it appears in the above photos. Bear in mind the battery is AAA. If you need longer run time and serious brightness, there is a Lumentop with a AA battery (up to 650 lumens), but no carabiner provided. The AA model has a strobe available, but a reviewer on Amazon states that you don't have to cycle into the strobe after cycling through the four different luminosities. Nice.
