SF Minimus (1CR123) Headlamp

Have had this model (Minimus) for a few years now, used it mostly for night hiking. Overall it is pretty good however a few improvements would be appreciated. First, there is no 'lock-out' for the battery as found on other SF lights, this is an issue because there is a parasitic drain associated with electronic switches. In other words even when off the light drains a small amount of power. Second, the optics creates a annoying light prism directly below the headlamp. While not the worst thing it would be better not to have it. Third, although not stated in the manual, use of Li-ion batteries (4.2volt) is not recommended and would void the warranty if used and found to cause damage. Being unable to use these batteries makes it less versatile.
Now while of course brighter and longer running would be nice too I'll say the light to date has been good. Fit and finish are tops, light fits comfortably, the field of vision produced by the light is nice and wide (bring a handheld with throw for spotting), and while lighter would be nice it's compact enough. I'd give it a 7 out of 10 as is with the potential to be a 9 out of 10 with improvements.

Excellent Pilots Night Flying Headlamp

As a pilot, I've been looking for a solid headlamp to use while flying at night. I've tried all of the usual suspects.... I adapted little flex boom tactical helmet lights.... all to lackluster results.

Then I tried the Minimus. This is an Excellent headlamp for the pilot in night flying scenarios. Clip on the red filter and you're ready to go. It is comfortable, has easy directional adjustment and the variable output adjustment makes dialing in the amount of light needed a snap. I recommend this headlamp to any pilot flying at night.

awesome headlamp

i've had a million different headlamps for hiking, camping, hunting, etc....but this light tops them all. the full adjustability of the light really is great for not using more then you need, but just the right amount. Then crank it up to see the distant objects--all while impressing your other headlamp wearing friends. great light, highly recommend it.

Combat Worthy

When our Son was deployed to Afghanistan last year. We wanted him to have the best equipment available. He told us he needed a head lamp and he had heard that Surefire was the best. We bought 2 of them in case something happened to the first we could send him the second. 9 months later and after many combat missions, our son is home and the backup headlamp is still in the box at our house. He reported the headlamp worked flawlessly and it is ready for his next deploying. His mother and I, on the other hand, are not.

Go Ruck

Bought the headlamp for the Go Ruck Challenge in Chicago (St. Patty's day 2013). It did not disappoint! Nice gear.

Very Good Headlamp

I had this headlamp with me in Nairobi for six months and it proved helpful numerous times because of rolling blackouts and unreliable electricity common in East Africa. I also hiked Mt. Kenya with the light, including an ascent starting at 0300. Never failed depsite cold temperatures and long run time.

Strongest points are adjustable head band, compactness, the adjustibility the point of aim for the center of the beam, and the wide range of brightness adjustablity.

The Minimus headlamp features a high-efficiency LED that provides a brilliant white light, adjustable in output from zero to 100 lumens via the knurled no-slip right-hand output control knob. The proprietary refractive optic produces a wide beam optimized for your natural field of view, and an included red filter gives you the option of low-signature light that also preserves dark-adapted vision. A valuable safety feature: a setting for a long-running SOS beacon. The Minimus runs on a single 123A battery contained within the tilt-control knob, and the battery access cap has a short leash to prevent dropping or loss. The fine-weave headband is strong but comfortable, and features a moisture-wicking Breathe-O-Prene™ forehead pad. Built from tough polymer and hard-anodized aerospace aluminum, the Minimus is lightweight, yet like its siblings the Minimus™ Vision, the Minimus™ Tactical, and the Minimus™ AA, it's tough enough for the rigors of combat, caving, and mountaineering, and is submersible to 3 feet for up to thirty minutes.
