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. The torch is powered by built-in 9600mAh 21700 li-ion batteries, rechargeable via a USB-C port at the tail end and compatible with QC (adapter sold separately).

The TM20K has a toggle switch at the base of the light to switch between daily mode, tactical mode and lockout. The brightness levels are operated by a metal power button on the tail end and a mode button on the side of the tail end. Additionally, the flashlight offers Nitecore's Strobe Ready function for fast access to the strobe mode and a power indicator built in to the power switch.

The torch offers a CNC machined, unibody design which is solid, durable and lightweight. It also provides excellent heat dissipation, combined with the cooling fins on the head of the light and integrated Advanced Temperature Regulation (ATR).
