I've had great luck with Fenix lights. If you truly believe that you'll ever be able to see the difference between a 90 lumen light, and a 100 lumen light, you're kidding yourself.
Using lumens as an indicator is a flawed yardstick, in the first place. A "floody" light will not appear as bright as a light with a tighter, more concentrated beam, even if they are determined to be throwing the same amount of lumens. Also, some manufacturers are very generous when they advertise the lumens of their flashlights, and some manufacturers are more conversative, and more accurate. It also depends on how/where the lumen measurement is being taken. Don't go nuts worrying about a few lumens here or there, be more concerned about the reputation of the manufacturer.
My personal preference is for lights that use a single battery. Then, there's no concern about the "balance" of the batteries, which can cause issues.
Also, be *just* as concerned with the lowest setting on a flashlight, as the brightest (especially on a small, multi-purpose EDC light). While a bright flashlight is great, and impressive, it's often the low setting that I find myself using more frequently, like at least 10 times more frequently than the brightest setting. First, because in a some low-light situations (movie theaters, restaurants, etc) where the blazing bright beam will not only annoy and distract others, it can also work against you, reflecting off of surfaces (good luck using a 100 lumen beam to read a laminated menu)...but it will also leave you with momentarily compromised vision, once you turn the light off. Secondly, if you should find yourself in some rather long-term situation where you are wanting light for some hours...an extremely low setting (like around 3 lumens, to as little as .1 lumen) will provide a usable amount of light (in near pitch black circumstances), but will have runtimes in the 20, 50, or even upwards of 100 hours or more, as opposed to perhaps one or two hours (if that) on a 100 lumen AAA light.
It also depends on what sort of UI (User Interface) you want, do you want programmable, last mode memory, the order of the modes (H, M, L,...L, M, H, or M,H,L), "hidden" modes, strobe, SOS, battery polarity protection, thermal shut-off, a more floody beam, or focused beam, or in between, tritium slots, pocket clip, construction material (aluminum, stainless steel, copper, brass, polymer/plastic, titanium), weight (see material), orange peel reflector, anti-reflective lens coating, level of water resistance (keep in mind, an exposed USB port will compromise water resistance)???
There are many fine manufacturers. Fenix, Streamlight, Lumintop, Jetbeam, Acebeam, Zebralight, Olight, and dozens of others. If you'd like to learn more about flashlights than you ever suspected was possible, or ever wanted to know...or you'd like to become addicted to a rather silly (and ridiculously expensive) hobby...go to Candlepower forums.com.
Good luck!
