Anyway, to output 20 000lm the TM20K uses 19x XP-L2 LEDs, one placed in SMO reflector for a decent throw, the rest just sits without optics (mule) to give a massive floodlight. This should cover any faults but to be honest I don’t know what would happen if the battery pack started to lose its capacity after 5 or 10 years. The Nitecore TM20K flashlight has been selected as a Red Dot winner of 2022, offering an impressive maximum output of 20,000 lumens from the 19 x Cree XP-L2 LEDs. For transport or carry, you can lock the TM20K, set it to daily mode for constant illumination, or set it to tactical mode for momentary illumination.Instead of using 2 different lights for different taskts, the TM20k uses 19 LEDs and reflector design to give you the beams you need for any kind of task. The 103 third parties who use cookies on this service do so for their purposes of displaying and measuring personalized ads, generating audience insights, and developing and improving products. That means each one produces just over 1000 lumens – something that’s fairly standard in flashlights these days. Shown first is an initial ‘High’ ANSI output trace (Section 1), then the Turbo button held for 30s (Section 2) where the output drops to High after 8s. The Low, Mid, High and Turbo levels use all 19 LEDs on, while the Ultralow level uses only the central LED (Spotlight) lighting.

Low mode starts at almost 900 lumens and gradually drops to 600 at 4 hours, then falls faster to 300 lumens, before turning off at 4:25. I have been using the flashlight for a month and already one of the buttons that is responsible for maximum power has broken. This seems about right, as after a run time from empty, it took about 4 hours 40 minutes to get to the point where it was trickling current into the cells. I know because in the past I (on numerous occasions) ended up with scorch marks on jackets and jeans. Please note, all quoted lumen figures are from a DIY integrating sphere, and according to ANSI standards.As well as a look round the TM20K, this review includes output measurements, runtime graphs, and beamshots to give you the true story of its performance. It is one-hand operable and equipped with the built-in 21700 Li-ion batteries and a USB-C charging port. Most of the modes use the spot and flood LEDs, with ultralow and spotlight modes only using the center one and the floodlight mode only using the outer ones.

All of that to talk about the TM20K not outputting anything, well, you will be very happy about this feature.

As assumed by the initials, Nitecore's new powerful Tiny Monster can deliver up to 20,000 lumens with a maximum intensity of 22,200cd, through 19 CREE XP-L HD LEDs, and covers a maximum distance of 290 meters with its beam.
