1: Yea, but if you don`t already have one...then how much.
About the same as the LS, depending on host body.
2: Yea, but how does the run time compare...and are`nt they close in brightness?
Apples and oranges, I'm afraid. The KL1 is designed to run best on 2x123 - a configuration that the LS does not support....No they really aren't all that close in brightness OR color quality
3: See # 2
As with #2. No again.
4: Well ...what about dependability? How often does a 123 batt driven device get used compared to a cheap as dirt to run AA.
No fair asking two questions per item number. SF gets high dependability marks for using a spring and a real switch. A drop on the head is much less likely to be catastrophic to the batteries. Part 2: As far as I know, most (at least many) choose to use the LS in the 123 configuration, so the answer is "quite a bit."
5: SUREFIRE...don`t get it...what does this mean?
I know the SureFires are not to far behind the ARC`s in quality...but still?
Uhh. This was NOT my comment. Can't answer you there. You may notice that I'm typically considered a shill for Arc around these parts, and here I am simply calling it like I see it.
No question that the Arc has features that the KL1 doesn't have. But you can't simply discount the KL1 as being inferior in all ways. If there were a perfect flashlight, there wouldn't be any more choices, would there?
