The TK61 LED Flashlight from Fenix is a powerful flashlight optimized for long beam reach and extended runtime. It offers output in four stages from 15 to 1000 lumens, as well as a strobe mode and SOS mode. A convenient dual switch at the base of the head operates the light. Runtimes vary from 4.3 hours at full power to 300 hours at 15 lumens. This flashlight has a glass lens with an anti-reflective coating and an aluminum alloy body with a premium type III hard anodized anti-abrasive finish. It's waterproof to 6.5' (IXP8 standard) and impact resistant to a drop from 3.3'.
The output is digitally regulated to maintain constant brightness, and there's reverse polarity protection to protect against improper battery installation. The TK61 operates on 8x CR-123A or 4x 18650 batteries and its Cree XM-L2 (U2) LED lamp has an approximate life of 50,000 hours.
