Paul,
Thanks for taking the time to provide your comments.
The Saint Minimus is NOT a pure floody lamp, at least the way the H50 is. It is floody, but has an aspheric optic that does a careful job organizing the beam for decent reach and spill. You could combine it with a mini-thrower like an E1B though that adds more weight and gets expensive. Carrot's review is here:
http://www.gearcarrot.com/blog/2010/03/surefire-saint-review/ (also
this thread) and if he's still on this thread he might have more to say. I'm not trying to give a sales pitch for it, I've just gotten interested enough in it from this thread that I might buy one (but that's just me).
This thread also made me aware of the Saint Minimus, and I liked what I saw. I thought about it quite a bit, but in the end decided I don't have a match at this time. Perhaps in the future. I sure can understand someone wanting to buy one.
I took the Saint Minimus' beam to be more like the H501 than the H50. The H501, which most people classify as floody, is also described as having a smooth beam that is a good match for your peripheral vision. I took the information from the
Saint Minimus web site to be supporting that point of view:
- Minimus produces a wide, variable-output beam optimized for your field of vision.
- Proprietary refractive optic produces a smooth, wide beam optimized for your field of vision
- There are no hot spots, rings, or defects; just a smooth white beam that corresponds nicely with your peripheral vision
From Carrot's review:
- In any case, the Saint creates a beautiful rectangular flood, softly tapering off on the sides,
I also ran across scattered postings at CPF describing the beam as floody.
That's why I thought of the Minimus as floody (H501 style). Note that H501 users say the light is fine for a lot of trail walking. I would assume the Saint Minimus is similar to the H501 in that respect.
Is your understanding different from the above? Perhaps if Carrot is still monitoring this thread, he can chime in if my understanding is way off base.
If you go with AA, your backup cell and maybe your main cell should be an L91 lithium. An L91 is half the weight of an Eneloop, has 2x the energy capacity, and works much better in cold weather. It's just not rechargeable. An L91 has almost the same weight, volume, and energy as a 123, but a different voltage and shape.
Agreed -- I did not mention that, but my thinking for AA is that lithium batteries make sense for at least the spare and use below freezing. I may try them for main use -- they do save about 0.4 oz over Eneloop -- but I prefer rechargeable for my in-use batteries where possible (just a general principles thing).
I'm not sure what your objection is to AAA since it's an obvious notion if you're trying to minimize weight, but you know your priorities better than I do.
If you mean for a clip-on, then I agree that AAA is probably the way to go. That's why I referred to the iTP A3.
As for a headlamp, if you want the possibility of using both a throw and a flood at times, AAA presents a problem -- the H01 is the only game in town. (A clip-on is not going to work well with a wool hat and a parka hood.) Furthermore, you would not be saving much weight -- here are some weights (including the spare battery):
- iTP H01 -- 2.8 oz (AAA)
- ZL H31 -- 2.9 oz (CR123A)
- ZL H50 -- 2.5 oz (AA)
- If the H51 weight is as much heavier than the H50 as the H31 is from the H30, then the H51 will weigh 2.8 oz
I wouldn't take anyone's lumen and IPX numbers too seriously (except maybe SF's) since they are mostly made-up marketing nonsense.
I am surprised at the IPX comments. I would have thought that pretty cut-and-dried. I do not attach any weight to the difference between the PT EOS claiming IPX7 and the iTP Ax EOS (IP68) and ZL (IPX8) lights. I would hope that they are clearly more waterproof than the ones that only claim IPX4, though. Are you telling me that is a vain hope?
As to lumens, expect that there are problems both with how they are measured and with what is measured. I was surprised to read somewhere that Fenix measures them at the emitter. As I think about it, I suppose that I should assume an emitter measurement unless the spec clearly says it is an OTF measurement. (Is there list anywhere of who measures OTF and who measures otherwise?)
If Fenix really does measure at the emitter, they may be doing themselves a disservice -- one of the complaints about them is that their low and mid level are too bright. To the extent that gripe is from spec reading, it could be due to how they are measured (which thought just occurred to me).
In any case, you note that my writeup did not choose lights on higher claimed lumens, especially not on higher max lumens. I am more interested in solid mid-level lumens (for hiking), nice low low-level lumens (for in camp and tent), and good efficiency (i.e. long run times). While more lumens on high power is welcome, all of the lights we are talking about have enough so that is not a deciding criterion.
There is a long thread about ZL reliability whose basic conclusion (iirc) is that the twisty ZL's work pretty well and the pushbuttons have had some problems.

I am still thinking about that one ...
I agree with most of your other conclusions.
