Fenix FD41 This 2-in-1 flashlight has the capability of a spotlight mode along with a floodlight with the 360-degree rotary focusing function. The FD41 features a floodlight with a wide beam of 81 degrees and a spotlight that has a beam throw of over 1,115 feet (340 meters). The FD41 is fitted with an optical lens with a total reflective coating. Revolving the focusing ring moves the head and the optical lens forward and backward from the LED, thus regulating the focus between spotlight and floodlight. It delivers a max output of 900 lumens. The tail switch plus side switch, compatibility with 18650 Li-ion as well as the cold-resistant CR123A batteries, makes the FD41 stand out when searching, camping and photographing outdoors.

    Very solid and durable flashlight. The focusing option is what sold me on it. Good quality beam with even coverage. Hard to find waterproof and dust-proof flashlights with the focusing option. Note: The 900 lumen output is only with the 3500mah battery not what comes with the light. I've had it for over a year and would reccomend it.

    This thing is amazing. It's the best flashlight I've ever owned. It can zoom in to light up something that is a few hundred yards down the road, or it can zoom out and light up an entire campsite. It's very rugged and built to last. I haven't submerged it yet, but it's been dropped several times with no ill effect at all, not even a scratch. The various output levels are well chosen, allowing you to use just enough light for a task and preserving battery life. The only negative I can find is that the focus ring is a bit stiff. I can adjust it with one hand but it's a bit of a struggle. It does seem to be loosening up a bit with repeated use, so I suspect it'll break in over time. It's also not that inconvenient to have to use 2 hands to adjust it, so as far as negatives go it's a very minor one. I would definitely recommend this light to anyone needing a versatile and rugged flashlight that should last a lifetime.
