Fenix TK41 LED Flashlight

With an 800-lumen maximum output mode, the Fenix TK41 isn’t an LED flashlight, it’s a light canon. Wow, just wow. The TK41 has 4-output levels – 10-lumen low-light, 108-lumen mid, 335-lumen high, and 800-lumen turbo modes.

Eight AA batteries power up the TK41, with battery life being about 240 hrs at low, 27 hrs at mid, 7 hrs 15mins at high, and 2hrs 10 mins at turbo output modes. A strobe mode operates at turbo brightness, and an SOS mode at mid-brightness.

Fenix sealed the TK41, making it waterproof to IPX-8 standards. An aircraft-grade aluminum body finished with type III hard-anodized finish means that the TK41 can handle quite a bit of abuse and should be durable enough for even the most demanding applications.

The TK41 is built around a Cree XM-L LED module, and is operated via a dual switch that offers separate on/off and output selection controls. Its dimensions are 1.55 inch diameter, 2.5-inch bezel diameter and 8.4 inch length.
