Nitecore Tube v2.0 Keychain Flashlight, 55 Lumen USB Rechargeable Ultra Lightweight Compact (Olive)

I've used a few different EDC keychain flashlights, and this Nitecore Tube v2 is my preference for a balance between light weight, ease of use, (can find the on/off button easily), brightness levels, and price.I like that I can retrieve this from my pocket and with two clicks can have plenty of illumination for most all my needs. I also like the ease of switching to the lockoff feature to prevent accidental pocket/whatever power on, even though I don't use this feature in my everyday use.The fact that the first click to power on enables very low illumination is great - I've used this a couple of times - once helping someone find their dropped glasses in a dark movie theater. The first click is low intensity to not bother anyone, yet still bright enough to be useful.I did once experience an issue with my Nitecore Tube v2. I contacted the dealer through Amazon, and within a couple of days my issue was resolved to my complete satisfaction. They do stand behind their products. I wouldn't hesitate to purchase from them in the future.

I love these and bought a bunch to give as presents. I have a version 1.0 for years I carry with me everywhere. The battery lasts a long time and charges quickly. Compact, lightweight, durable, and bright. Wish it was USB-C, but the connector would be much bigger, so that might be why they are sticking with MicroUSB.

This is the ultimate ultralight tent light.

I'm using this as my primary light for hikes, and on it's lowest setting, and once my eyes are adjusted, it works just fine and that is on crappy trails with hardly any footpath. Not too bad, and the battery should last 50 hours at that setting, unbelievable! So happy I got this light and such a savings in my backpack. It's so light, it goes in all my hiking packs, might as well. It's only 12g with a shock cord!Long term use update**So I've been using the nitecore tube as my primary hiking light for 4 seasons now, and it's still going strong. If I know I'm doing a lot of night hiking, I don't take this though and rather opt for a nu20, but for all my standard backpacking trips where I plan on being at camp before dark, I bring my tube along. It charges up nicely using a powerbank and the light lasts a very long time. I don't even need to use it at peak brightness, I can get by at about half brightness. I like mine, and I now have three of them. Very happy with the product.

The Nitecore Tube V2 is an excellent candidate for upgrading from a key fob to a flashlight key fob or for upgrading from a less capable flashlight key fob.To summarize, the size is suitable, the output power range useful, the output power variable, the light distribution suitable, the run times good, and the interface excellent (nearly every operation is a "shortcut", including high, low, and variable output levels).There is one catch within the user interface: a "bright trap". Trying to turn off the Tube "too soon" (i.e., just after switching it on to low) just switches it to high. Once I discovered this, I found it easy to avoid by letting the light run very briefly before switching it off.Hint: To get traditional fob orientation relative to the key ring, check with your local tackle shop or sporting goods store for a #6 (or "size 6") stainless steel split ring to install between the flashlight and key ring. Subhint: ALSO check for installation assistance unless you have split ring pliers (not snap ring pliers) or other ability (& experience) to work with such things. The small, strong split rings can be VERY frustrating (nearly impossible to install) without a suitable tool.The two key rings supplied are just over 15/32", about 12 mm, and just over 25/32", about 20 mm, diameter, both smaller than the 1+1/8" rings I'm accustomed to. This was a nonissue: I just transferred my in-use ring (and keys) to the Tube V2.Accidental activation ("hot pocket" if it were more powerful...) resistance is situational. I've not yet had a single accidental activation, likely due to both the combination of things in my pocket and the way I set 'em in place. Others have reported accidental activations, and I can understand why. With a broad pusher, activation force of my light's switch is a seemingly-appropriate 3.5 lbf (1.6 kgf). However, for a narrow pusher the force drops to a mere 0.75 lbf (0.34 kgf). So, it's just a question of whether some pointy aspect of some object is likely to land pointing onto the middle of the switch; seems not to happen to me, but your experience could differ.Strobing (popular misnomer: PWM) is nearly absent. I can detect strobing only at lowest power (by very quickly waving the Tube V2 in a circle while observing it in a mirror). I've never noticed the strobing in use.Size tidily compares to traditional "medallion" key fobs: the leather "sloped oblong" bearing a medallion with a brand logo, sports team logo, or such. My Tube V2 _just_ fits within the outline of the leather, and the thicknesses are similar too, so the Tube V2 is technically smaller due to the leather fob's greater width.The accompanying "Lumentac" or "Longhorn Tactical" light is nearly identical to a Photon Micro Light II, so information regarding that light may prove "illuminating" <grin!>.Quibbles:I'd like a way to assess battery state of charge, but for the low price that may be too much to ask.I'm curious whether the micro-USB port cover will prove adequately durable.

This compact little two-setting light is just right for my needs. I use the low setting for getting around the house after we have all gone to bed, and it is plenty bright for that purpose. The high setting is surprisingly bright, and I just use that occasionally when I need to get a better look at something. I love the fact that it is rechargeable via USB, as I was getting tired of replacing all those expensive little button batteries in my previous light. This light is small and light enough to just drop into your pocket if you are one of those guys (like me) who likes to carry a flashlight pretty much everywhere. (There is a simple procedure that allows you to disable the button so it won't accidentally activate in your pocket).I do have to warn you not to look directly into the LED, especially while it is on the high setting. It is extremely bright at close range and it will blind you and have you seeing spots for quite awhile. Take my advice: Don't look directly at the sun, and don't look directly at the LED.
