There's enough mechanics, as well as firearm & outdoor enthusiasts on here that there's sure to be some good suggestions.
I'm in the market for a flashlight, I've had a few Maglites of various sizes, I've got a Petzl head lamp I really like, and I've got a few various hardware store "checkout line" flashlights, i.e Dorcy, Lux Pro, etc. but I've never had a real good, high quality light.
What I'm really looking for is a handheld, LED, capable of being weapon mounted via traditional means, i.e. ~1" diameter body, use 2+ CR123A or a 18650 batteries (not interested in AA, AAA, etc.), ~200+ Lumens (bright), simple on/off preferred, no disco strobe, don't need eleventeen settings, and bonus points for a readily available "tactical" remote switch. When it's all said and done, the light needs to meet all that criteria and be mounted on a firearm for <$100.
I've read reviews and researched lights until I'm cross eyed, and have started a list of candidates. Most lights are in the $70 or less range to leave budget for mounting and/or remote switch.
Surefire G2X Tactical around $54 on fleabay, simple momentary button or twist end constant on, 320 lumen, available remote switch from several manufacturers, 2 hour run time. I know some folks who detest Surefire though, and some reviews say this isn't the best option for weapon mounted light since there's only a spring for the batteries on one end.
Streamlight TL-2 C4 LED around $60 most places, simple push button click on or press momentary, marketed as a weapon mounted light, 3.5 hour run time. Remote switch is available but expensive, and it's only 160 lumen.
Streamlight Protac HL around $70 from most places, crazy bright 600 lumen, has eleventy billion settings, but can be programed to simple on/off with click. Surefire doesn't make a remote switch for the Protac line, and doesn't appear that there are aftermarket sources for one either. I expect it will suck batteries dead pretty quick at 600 lumen, only 1.25 hour run time on max.
Sightmark Q5 Triple Duty around $65, 280 lumen, EVERYTHING you need to mount the light to a picatinny/weaver rail and remote switch is included, simple push button on/off. Only 1.5 hour run time, Sightmark doesn't have the best reputation for optics, are new-ish to tactical lights, but everything I've read has been positive.
Fenix TK09 around $60, 450 lumen, affordable remote switch, 2 hour run time on max. Three modes, low, mid, high, instead of on/off, seem to be love or hate no in between, many can't shut up about how great they are, wile others say they're junk.
Those are basically what I've whittled my suggestion down to. I've been through the catalogs of Pelican, Olight, Foursevens, and I'm sure a few others I'm forgetting, but haven't come across any better solutions, not saying that I haven't missed something. Everyone seems to want to put so many functions on their lights, while I'm sure they're great lights, I don't want to be clicking through a dozen modes to get to the setting I want.
Anyone have any first hand experience with any of these lights, or suggestions of others that might work?
