The Fenix TK41 is powerful, tough, and compact , making it an ideal choice for outdoor searching, caving, or using as a spare light in vehicles.The flashlight, which runs on eight AA batteries, is equipped with a Cree XM-L LED bulb with a lifespan of 50,000 hours. The bulb's digitally regulated beam maintains a constant brightness during your activity, so you won't have to deal with a dimming light while you search. In the process, the TK41 produces four brightness levels: low (10 lumens), which runs for up to 240 hours; mid (108 lumens, 27 hours); high (335 lumens, 7 hours 15 minutes); and turbo (800 lumens, 2 hours 10 minutes). Add in two flashing functions--strobe and SOS--and you have a light that can meet your illuminating needs unconditionally. [ Shop Now ]
