PEAK's EIGER 10180 could be described as a tiny little mountain of a light.

For those unfamiliar with PEAK LED SOLUTIONS lights, let me briefly describe the construction of the lug-bodied 10180 Eiger. On the outside it is somewhat similar in appearance to the ARC AAA and has a very simple body tube with a key lug on the tail and two wide bands of tasteful knurling covering most of the length of the body. The knurling is not at all aggressive, but adequate for all except the greasiest of hands. The head has six milled flats in a stylish pattern. My Eigers are brass and quite beautiful. Workmanship is superb and the brass polishes up very nicely. Threads are silky smooth. An O-ring provides a snug fit to seal the battery compartment which holds a single battery, positive terminal facing forward. The negative contact is machined into the tail end of the case and is surrounded by a small foam washer to prevent battery rattle.

Operation is simple: twist on, twist off.

This Eiger uses the miniscule 10180 rechargeable battery which is 10mm in diameter and 18mm in length. The overall size of this Eiger variation is easy to describe - the whole thing (including a key lug) is smaller than an AA battery (14mm X 50mm).

It will actually fit entirely inside any other standard light which uses a common AA battery.

In the pocket version (available in either brass or stainless) the Eiger 10180 will fit in a teaspoon. Incidentally, the wide beam variation described below uses a shorter reflector set into a head which is shallower and therefore shorter (similar to that of the 5mm ARC AAA), further reducing its already tiny size.

A size comparison with a number of other lights also helps illustrate just how very small this Eiger 10180 really is.

The LED used is a 0100 bin Rebel available in either a natural (fairly warm) or a cool tint. Three beam profiles are offered: wide, medium or narrow. The medium uses a collimating optic while the wide and narrow versions use reflectors. All are covered with a lexan window.

The circuitry, like that of all PEAKS, is potted for protection against shock and moisture in a heat-transferring epoxy, and it is the same circuitry PEAK has used in all its Pacific and Baltic P4 lights. The positive terminal is a very solid gold-plated brass button.

Because the Eiger head can be utilized with any PEAK Matterhorn body, the casual user or twisted Flashaholic can choose from a dizzying array of available body and tube configurations. These include the 2 X AAA, AAA, 10280 and 10180 bodies, in either HAIII, Brass or Stainless, and in either keychain/momentary, lug or pocket styles. The 10180 body is produced only in lug and pocket styles. The product line-up sticky in the Peak Sub-Forum describes these Matterhorn variations in great detail. And, of course, you can order extra battery compartments in different sizes for the Eiger.
The Eiger is manufactured and can be ordered in one of eight different power levels. At Level 1, light output with a 3.7v LiIon 10180 is about equal to that of the ARC GS. Level 2 produces around 18 lumens at the same voltage. Level 8, the highest, is rated to produce about 100 lumens with a 3.7v LiIon cell.

Performance is nothing short of phenomenal!

The Level 8 light output from the Lilliputian 10180 Eiger equals that of a 3D incandescent MagLight, or that of the P1D on medium. The first time I lit it up outdoors I was stunned! I really hadn't believed it possible to get so much light out of such a small package.

But sadly, performance at such a high level comes at a price. The capacity of the 10180 LiIon cell is just too limited (only about 90mAH) to produce a very useful runtime at 100 lumens. At any of the higher power levels, the current from the cell very quickly drains it. And if drained too far, battery life suffers. But on the positive side, it isn't possible to run it long enough to generate more heat than this tiny light can handle. I've since swapped out my Level 8 Eiger over to an AAA Matterhorn body and have loaded it up with a 10440 which with about 320mAH has enough capacity to take advantage of the potential of this phenomenal little light at the higher power levels. Although the 10180 cell, at 3.7v, can really produce a WOW effect, it really isn't practical so I would not recommend Level 8 with the 10180. Even the 10280 would not likely support that power level long enough to be worthwhile for most users. The higher levels should probably be reserved for Eigers with either an AA (10440) or a 2 X AAA configuration.

My 10180 brass body now sports a Level 2 head. This is where the Eiger 10180 really shines - at the lower power levels. Here, output is still great, significantly exceeding that of the venerable and much larger ARC AAA, and runtime is dramatically improved over the Level 8, enough to be practical.

Others have previously posted beamshots of the Eiger so I'll not clutter things up here with more of the same (I'm not much of a photographer anyway). But one thing that immediately becomes clear from observation of Eiger beams - whether outdoors or against white walls - is that they are very, very clean. No ugly artifacts, no distracting rings, no unevenness, nothing at all to detract from the useable light downrange. They are, in fact, the nicest beams I've seen on any lights, period. This applies equally to the natural (warm) tint and the cool. Honestly, I'm not the best judge of tints (having even been called a fool for preferring nice blue tints on my old 5mm's), but the natural is too warm for me, though others will no doubt have their own preferences. The cool, on the other hand, could not appear more perfect to my tired, old eyes. It's totally subjective, but I can't see any tint at all in the cool.

To briefly summarize, PEAK LED SOLUTIONS new Eiger 10180 is an incredible little light. Beautifully made with many build and performance options, this is a light for every keychain or pocket. Quite simply, the 0100 bin Rebel in the Eiger has in my opinion stuck another nail in the coffin of 5mm LED's, allowing for amazing performance levels in ever smaller packages. This isn't your Father's old flashlight.

Re: My review of new Peak Eiger 10180

Thanks for the review. Looks like you got yourself a nice brass collection there. The level 2 head with a 104400 cell should offer good runtime and output.

DwF,

Thanks for a great review, and---despite your modesty---very nice photos. :thumbsup: Your brass Eiger collection has me envious---great stuff there!

The biggest challenge with the Eiger series is sorting through all the possible combinations---with a large enough flashlight budget, it could keep a Peakaholic busy for months!

You mention runtimes in the review- might I ask what the times were?

I haven't measured the runtime at level 2 - doesn't much matter if you keep the cell topped off - but it definitely is long enough to be practical. Level 8, however, is another matter. I have accurately tested a new 10180 with a measured full charge. The voltage dropped to 2.0v (the minimum suggested to avoid damage to the cell) in just two minutes.

This rapid power drain is not too much of a disadvantage with batteries of greater capacity (like the 10280 or 10440) if the user is able to recharge them frequently. In this connection, the real problem with the Level 8, however, is not the Eiger's hunger for power. The real problem is that 10180's are a miserable pain to recharge. I was able to find a coin cell charger that works as advertised, but at 20mAH or so it takes forever: nearly 5 hours! 10280's and 10440's, on the other hand, are a breeze to recharge quickly with NANO's which have worked perfectly for me.

Perhaps I've been hanging around CPF too long, but I still play around some with Peak's little level 8 Eiger 10180 because its output is so remarkable and because it's so beautifully made. With a handful of nice lights always at hand, runtime no longer seems nearly as important as it did when I bought that first good light.

Do you have the narrow, medium or wide beam profile on your '2' head?

Edited to add:

I would love to hear what the runtime is on the '2' head as well. I just today received a 10180 and 10280 SS keychain bodies with a '4' medium head as well as a '6' head on a Baltic(?) body.

I'm wanting another head for the 10180 body and don't know if I want the 1 or 2 head and which beam profile to choose for the lower level options (I'm leaning towards wide).

nice pics- gotta love the brass- looks like wide emitter-shorter- what power level and tint did you get and what type of charger are you using- nano?

Wow - that is really small! Very impressive although in that size format it appears that realistically you need to be looking at level 2 or maybe 4 to have any runtime at all. I only use a keyring light in short bursts - but 2 minutes or so of runtime is not quite enough even for my sporadic uses...

It is tiny...I am thinking that level 1 or 2 would prob. outshine an older XLR LuxIII Baltic- sweet little light.

I have a medium-beam level 6 10180, and for its intended purpose I could care less what the runtime is. For sustained illumination, I have any number of RCR123-based lights; all I'll ever use my Eiger for is short bursts to plug in computer cables, find stuff I dropped on the ground, fiddle with during meetings, etc. I like it a lot.

what is the reaction you get when you show it to people?
when I show anyone my 10440 #8- and tell them to turn it on-they are shocked-espcially since i got a set of 10440's.

I haven't shown it to anyone yet. I got tired months ago of people saying "Jesus, you bought another flashlight? How many do you have? You need a hobby dude."

As one CPF member's signature points out, there's a 100% chance of nighttime in the next 24 hours, and nighttime is when I do my walking and most of my biking and working on my car, because I have to work during the day. It seems natural to expect I'd have a greater interest in portable lighting than the average person. But I'm preaching to the converted here, fortunately. :)

Anyway, my reaction to it was overwhelmingly favorable. :twothumbs

That's all that counts. I get the same thing-people are all like "you paid HOW much for that light"- these are the same hipsters who spend $60 bucks a week on Starbucks Lattes- who's investment will last longer?!!?:whistle: I rest my case.

But dude...Starbucks is cool. And more importantly, it makes you cool by extension. God, don't you get it?!?
