And the advantage of that over the Fenix's, other than that it can be turned into a headlamp with the Prism?
A few dollars cheaper. I recommended the Quark 2xAA Tactical (not the Regular) because the UI allows it to act like a simple two-mode light, but the two modes can be set to any of the available levels. Also, the protruding tailcap might be a bit easier for gloved hands. And the Quark's "moon mode" is significantly lower than the low of the Fenix, if you want to absolutely maximize runtime. If none of these are important to you, then the Quark 2xAA Tactical offers no advantage over the Fenix LD20.
Perhaps I should get more basic than this. What makes one light "better" than the other? I mean... throws, OK, beam size and features, right, battery life, OK, digital v. manual, OK, fine. Right.
But comparing two lights that have roughly all the same amounts of those things... I honestly am not sure how to compare, say, the Fenix to the Quark. I just think I don't know enough.
What makes one light "better" than another is really dependent on what you need the light to do. What is better for me may not be better for someone else and vice versa. That is why whenever someone asks for advice on a flashlight the most common reply is, "what do you need the light for?" The intended usage is a key factor in determining what is a "better" light. Beyond that, there are also items like budget, personal preferences, etc.
CPF often recommends "buy 'em both!" When we do that, it is not just to get you to spend your money. We also recognize that a lot of times, a person just needs to try two or more comparable lights to find out which one has that "X factor" that makes the light right for them. So we say "buy 'em both" so you can try it for yourself. You can always re-sell the light(s) you decide are not the best for you. CPF Marketplace will take care of that.
