Newest member, first post, ancient thread! But with the last posts in mind, it kind of feels right. 
I’ve been using the R5-A3 as my EDC for many years now (if it was released in 2010, i probably got my first within a year). I’m on my sixth, but only one has failed on me, after taking a Long drop onto concrete (5th floor), the rest I’ve lost. And at less than $10 a piece, a more expensive light wouldn’t have been less lost!
Battery life may well be atrocious, but it’s all down to what you need!
I’ve been moving around the suburbs of Stockholm, Sweden. Where most walkways are lit, but there’s also fairly large swathes of forest, unlit and unkept for centuries.
My permanent companion has been my dog. Jacqueline, a Pitbull with a touch of Rottweiler, built like a Whippet on steroids. (20”, 50 lbs).
With time I got her to stop chasing Hare and Roedeer, but it didn’t come naturally and it wasn’t perfect…
So now and then I needed to be able to; 1: see where she’d gone of to, and 2: check a large area for game. (And on occasion, find a turd to pick up).
Neither of these applications require a lot of time, but a throw of a hundred metres (or more, when eye-shine is enough) from something as small as this, has served me admirably well!
On top of that I’ve been able to make security guards and police almost shit themselves by helping them light up whatever their flashlights wouldn’t, from several times the distance. Get a friend into a club by “helping” the bouncer see my stamp, and then waving my friend by since all he could see was a pink/orange afterimage of my pasty white wrist. Surprising the dancefloor of a small underground rave, or four, with a strobe that shouldn’t be. And helping more than a few people scale some damn treacherous cliffs when at a mini-festival in Croatia, where the party was on the beach and the camping ground some 50 ft above. Although on that journey I did feel the lack of longevity and a decent Low mode…
I absolutely love the intense beam, with just the right amount of bleed/flood to light the path, while still reaching deep into the woods.
What kind of reflector typically does this? Enough light to light the way is very little, but to be able to look ahead properly, you need most of what’s available focused. This goes especially for bike lights and such! (This kind of beam won’t blind as much either, as the majority of the reflected light will be far away).
I’ve been using 14500’s. First UltraFire, as I didn’t know better, then TrustFire Flame, and lastly Keeppowers, with the Sanyo cells which were said to be top of the line for the purpose back in 2015.
Now the dog is dead since a year and some, she got to be twelve years old, still fit as a fiddle, but succumbed to leptospirosis… After killing hundreds of rats, a rat finally got her, indirectly.
And I’m looking for some more serious lights. I’m still mostly after the “LET THERE BE LIGHT” type beasts, in as small a package as possible (I mostly dress in a three piece suit, kind of, and don’t have anywhere to put something much larger than a 18650 battery, or an R5-A3).
