Extremely Powerful and Small
May 21, 2020
The is a very high powered light packed into a small body. On turbo you get 4400 lumens (in less than 5 inches length) with a decent run time of 30 mins and on high you get 1050 lumens for 3 hrs15 mins. The main problem with it (for which I took away a star) is the UI, as someone else mentioned. It is overly complicated and difficult to remember how to get to settings unless you use it frequently. However, it does have a last setting memory, which helps. The amount of light out front on turbo is in the neighborhood of that produced by the Tiny Monster series, but in a very compact form. If they would only streamline the UI, I would unhesitatingly recommends this light. As it is, it still is state-of-the-art.

Very brite

For a small light this thing is powerful. Very easy to use with one switch and it has all of the bells and whistles. The only thing I don't like is the batt that comes with it has USB charging but has to be removed to charge it.

Awesome light seriously hampered by a horrible UI
April 17, 2020
To start, the good parts: the form factor of this light is great, and the output is astonishing, even if it can't keep up the blazing turbo mode for more than about 20 seconds. The USB-C port on the *battery* is a strange choice, but seems to do the trick.

What kills this light for me is the UI. It's definitely different compared to other Nitecore lights, but that's not necessarily bad! Several individual "papercuts" make the UI downright *bad*:

1. Turning the light on is slow: it requires holding the power button down (pressing it briefly once just shows the battery level). I'm sure this was done to prevent accidentally powering the light on in a backpack, but it's irritating.

2. Changing modes is slow:: it requires holding the power button down past when the light turns on, then waiting about one second per mode as it cycles through ultralow/low/medium/high/turbo.

3. Changing modes is potentially physically painful: You can't start at ultralow; you're stuck at whatever mode you last used (and using the double-click-from-off shortcut to get to ultralow doesn't get around this). This means if you want to go from medium to low, you have to start with the light off, hold the button down, wait for it to turn on, wait for it to cycle to high, turbo, ultralow, and then low, then release the button. If you're in a dark environment, you've got two choices: point it somewhere and scorch your eyes, or cover the end of it and burn your hand (it gets that hot in the one second it's on turbo!).

4. If you start with the light on and try to turn the light off (one click from on) and turn it back on in ultralow (two clicks from off), you risk entering turbo (three clicks from on) accidentally. I've done this twice in the first hour of using it and it's annoying as heck.

I'm probably not returning this because of the UI, but there are folks who are, and I entirely understand their decision.

Super-nice light

Small size, but great features; especially the very low end and great coverage in turbo. It's blindingly bright!

"Tiny" Tiny Monster
February 29, 2020
I believe this light would fit into the Tiny Monster category quite easily. It's smaller than some of the 18650 lights that I own, and way, way brighter. Output modes spaced perfectly in my opinion and when you call on that turbo mode, holy cow !!! When out with the dog on the night walk 50 lumens is the normal. Press and hold the switch and prepare to be amazed. What comes to mind is those construction lights you see crews using doing night work on the highway. Stupid bright really, but if you want to see all the trees around you light up, press and hold. Instant access to ultra low, memory, turbo gives operator multiple lighting options. Switch is large and easy to find even with gloves on. Will turn on in front pocket so I loosen the tail cap to prevent accidental activation. Battery capacity is excellent. Been using about a week and a half and still showing 4.1 volts. That's with numerous short bursts of that incredible turbo mode too. Great job designing and building this one Nitecore.
