The mode-switching takes a little getting used to, but is ultimately fairly intuitive. From off, a rapid/short press activates moonlight mode, a normal press activates the last primary mode (moonlight, low, medium, high - all reasonably spaced), and a double-press goes straight to turbo. In primary mode, a normal press moves up then down brightness levels. A double press cycles to turbo, normal presses cycle through strobe, SOS, beacon, "dragon breath" (slow pulse of the switch backlight), then back to primary mode in moonlight. The switch itself has a handy battery indicator, cycling blue/purple/red to indicate state of charge. All of this might sound a little complicated, but it is explained in a diagram that comes with the light and ends up being fairly intuitive in use.
A quirk when using 14500 Li-Ion cells is the lack of a moonlight mode: the primary mode set is more like low/medium/high/turbo "lite".
The battery compartment is a little different from most multi-cell lights I've owned. Their is no carrier - instead there are milled recesses for each cell that retain them well enough that cells are retained laterally. I accidentally determined that the reverse-polarity indicator works as advertised once. The body of the flashlight is electrically neutral - due to the free-spinning contact insert in the tailcap (registered by prominent pins) it need not fully seat to make contact; this means that for longer-term storage you will need to remove the cells lest you end up with a completely dead light in a few months with no physical power switch to break the circuit. The tailcap O-ring seems a bit oversized - it tried to walk out on me once so I'm careful when screwing the tailcap back on.
The manufacturer claims a constant-current circuit and I believe them based on the perceptible tint shift towards yellow in lower modes and the lack of strobing effects both moving the light rapidly across one's field of view and against highly reflective objects. Like most lights with relatively wide, deep reflectors, the MK41 throws quite well - from ~36" the primary hotspot is about 4" in diameter, falling off rapidly into primary spill about 17" in diameter then secondary spill in a ~120° cone. For routine usage - navigating on foot in darkness, task work - the tight concentration of output into a small area limits the utility of the flashlight; while Manker markets the MK41 as a thrower on their website, one wonders if a diffuser is available. With a flat bottom and a reasonable girth relative to its height, the light tailstands well on a flat surface and can light a room well via ceiling bounce.
With its pleasant heft, the MK41 should be able to sustain turbo for longer than most single-cell "pocket rocket" lights before thermal limits kick in and it starts ramping down. But heat production is heat production and after less than a minute of turbo the head does get noticeably warm; after about two minutes it's unpleasantly hot. This is markedly better than my Astrolux S41 which starts to warm up in seconds on turbo.
Glancing at the Cree XHP35 data sheet, one does have to wonder if 2000 lumens is possible out of the "HD" version. The top E4 flux group for the cool white 7000K thru 5000K bins top out at 706 lumens @ 350mA under lab conditions (25° C) and 635 lumens under more normal conditions (85° C); driving the LED at peak rated of current 1050mA should result in 240% rated output or 1694 ideal / 1524 real-world lumens. With the thermal safety built into the lights, some currents beyond 1050mA could be applied to get to 2000 lumens without cooking anything.
Overall I'm satisfied with the purchase.
This flashlight has many great features. The first, being its ability to use AA batteries (four of them) or 14500 lithium batteries... also 4. Of course perhaps the best choice, is 1.2v NiMH rechargeable cells.
The output of the light is quite different depending on the batteries used. Using AA's you'll get a nice low moonlight mode which can be SET anywhere from 0.1 lumens to 5 lumens. Within this range, there are 21 individual settings. Just set it at the level you want, and that's where it stays, even through battery changes! Meanwhile with 14500 batteries, you don't get that choice. "Moonlight" with lithium batteries, is about 60 lumens!! The other modes are low, medium, high and turbo. Strangely though, I did a comparison of the modes with AA's and 14500's, and truth be told, (except for moonlight and low) there's not much difference. Each mode, regardless of battery, is within 200 lumens of each other, and that's not something the naked eye can actually "see". If you like having a properly low moonlight (like me) then you'll want to use AA's. If you want the absolute brightest light possible, then choose lithium.
It's an easy to use flashlight, and just like the first reviewer said, the button is a tad stiff. One of the neat things about it, is the way it cycles the modes. The sequence is moonlight>low>medium>high>turbo...then in reverse, from high to moonlight...and back again! The button also acts as a battery indicator. Blue means full charge, purple 50% and red, under 10%. There are also 3 emergency modes; Strobe, SOS and Beacon, plus one flashing mode --- called 'dragon breath'. This is where the side-switch slowly blinks on and off.
Tale a look at the pictures I've attached... which show the beam on turbo mode.
