Nitecore TM20K

Product Information

In the evening test, in the dark, I appreciated the large angle of illumination available to the TM20K; the distance covered by the beam is discrete, allowing good illumination at small and medium distances.

It is one-hand operable and equipped with the built-in 21700 Li-ion batteries and a USB-C charging port. If you've been looking for an upgrade to your clunky old power bank, this is the best power bank out there. Join me in this Nitecore TM20K review, 20K being the 20,000 Lumens, yes, 20,000 Lumens output from a palm sized light. All of that to talk about the TM20K not outputting anything, well, you will be very happy about this feature. Modes are selected using the toggle switch and Strobe Ready technology allows for instant access to strobe from any state.

Products shown, tagged or featured on YouTube by creators are sold by merchants and are subject to merchant's terms and conditions. The Daily mode ‘Floodlight’ and ‘Spotlight’ special output levels plus the ‘Turbo’ 20,000 Lumen mode. The light itself, including the familiar documentation, is hidden in the holster in between the foam of the box. Probably lighter than you expect a 20k lumens flashlight to be, but it "gets" heavier the more you hold it. The toggle switch can lock the TM20K for transport or carry, set it to daily mode for constant illumination, or tactical mode for momentary illumination.

I have had a couple of accidental activations by storing it in a jacket pocket so just beware the button protrudes slightly.

It sadly is not a straight line, but rather slowly falling to a 220 min point where it started to fail rapidly.

This flood and throw combo is similar to a few other lights, like the Acebeam X10, Olight Marauder 2 and upcoming lights from Intl-outdoor and Wurkkos. The (at the time) spectacular TM10K recently welcomed a big brother which, as the name already suggests, has double the amount of output.One of the most important features for a light like this is the lockout; yes the ‘not outputting any light’ feature. While locked, if you slide the toggle to 1 or 2, the power button flashes five times to let you know it is locked. As mentioned before the light will only start with the central LED light in the middle; only for the three subsequent modes the remaining 18 LED lights in the edge of the head will work as well.
