TK17, TK21R and LD35R: New Fenix flashlights with USB-C previewed

Fenix plans to launch the TK17, TK21R, and LD35R flashlights over the next few months. This was announced at IWA 2025 in Germany. All three flashlights can be charged via USB Type-C, but not all of them offer a built-in charging solution.

The LD35R might be suitable for tinkerers who are often working on desktop PCs. It has a magnetic back and a secondary light that shines in two directions and can illuminate surroundings with up to 100, 150, or 350 lumens. Unfortunately, Fenix doesn't provide battery life estimates for this mode. In addition, there's a red and blue LED that can flash in alternation or be used for SOS, which is red only.

The flashlight's main LED has a throw of 376 yards at 1,700 lumens in Turbo mode, which can be used for 2 hours and 40 minutes. Runtimes for the "High" setting with 800 lumens are not yet available. Alternatively, 350, 150, or 15 lumens can be used for 6, 18, or 119 hours, respectively. The "R" in the product name indicates that the flashlight comes with a charging port.

This feature is missing on the TK17, which means that the battery has to be removed and charged externally via USB-C. The upcoming flashlight with a robust and IP68-certified design with 30, 350, 1,000, and 3,500 lumens. It has a throw of 33 to 328 yards and is powered by an ARB-L21-6000B battery. This battery is relatively similar to the new Fenix 21700 battery with 6,000mAh and 21.6Wh, which we have already reported on.

Last but not least, the new TK21R is closely related to the TK17. It's slightly longer because it has an integrated charging components, including a USB-C port. Another difference is the Turbo mode, which is where the TK21R only hits 3,200 lumens. The throw or range has not been specified yet.

Fenix further indicated that sales of chargers in general are declining, as customers seem to prefer flashlights with a more convenient USB-C port. However, this doesn't mean that flashlights without USB-C ports will disappear from the market. Products like the TK17 remain important, especially in the professional market, where compatible chargers are usually kept on hand.

The TK17 is scheduled to hit the market first and is expected to launch in April 2025 for roughly €100 in European markets. The TK21R will follow a month later with an MSRP of €130. Fenix didn’t provide any pricing details on the LD35R, whose debut is set for this summer.
