I should have been in bed almost three hours ago, but UPS came earlier than usual, and I've been comparing the Minimus to the H30w that I use while backpacking, and for night hikes, along with a couple other lights.
Here are some initial impressions. Keep in mind I do not keep very many lights around, and therefore do not have many to compare it to.
Cons:
-It's huge. It's literally twice the length of the H30w, and .5" longer than the H60w that uses 18650s. Heavier, too.
-It sits further off your head than a Zebralight, giving the impression of even greater size(it's comfortable, and not too heavy, thankfully, but in the mirror, you look like a rhinocerous that ran into a brick wall, and you are definitely conscious of the fact you're wearing something on your head at all times).
-The artifact issue has NOT been eliminated(isn't noticeable in use, but very obvious on a wall).
-No support for 3.7V R123s, as far as I know. Eliminates the possibility of me buying a second Vision for work if I like this one.
Pros:
-Very high quality. Great construction.
-Ergonomics. I listed the size and sitting off your head as negatives above. The flip side is that the knurled knobs are very easy to reach and use.
-It's built like a tank. This is the stoutest headlamp I've ever seen.
-The mounting system is solid, as are adjustments to the angle of the headlamp.
-Adjustability of the brightness is fantastic. Fast, easy, infinite.
-It's dim. Lowest output is significantly lower than my Zebralight SC51Fw's L2 advertised at .16 lumens. My multimeter only reads in multiple of 10mA, so 10mA is what it shows at lowest.
-It's bright. Highest output is probably triple the SC51Fw's H1 advertised at 164 OTF lumens. Pulls about 1A at max output.
-It's everything in between. Runtime for my use will not be an issue. My H30w on medium draws ~50mA from a CR123A, and is more than I need for night hiking. Due to the more concentrated beam, similarly usable output from the Vision draws ~30mA.
Subjective:
-The tint is hard to describe. On a wall, it varies throughout the beam, much like my Malkoff M61N(but with a different mix of color-more red, less yellow). Either way, based on taking it into the closet and looking at my clothes, color rendition looks excellent. I'll have to try it outdoors, and with a wider variety of colors. I'm a pretty drab dresser...
