the lumen over 600, powered by one CR123A battery

Welcome AngryFox. I don't think so. Unless you count a modified/altered light. I think the only stock light out there that's close is the Sunwayman V11R on a 16340 which is 570 lumens...

How so? Their website says the operating voltage is 0.8-3.2 volts. I don't see 770 lumens anywhere on their page...?

Gotcha, thanks ;-)

There are loads. Any light that can support direct drive (the earlier mentioned EagleTac), will see this output level with an XM-L2 emitter.
Runtimes however are terrible.
An 18350 light is a bit better. Convoy S2+ shorty with the 7135x8 driver probably makes easily in excess of 600 lumens OTF.

Angryfox, you said CR123A. Do you include 16340 li ion in your question? You are getting answers for li ion. I prefer primaries so when I see CR123A I think primary.
Same here.

JETBeam RRT0SE. Sweet light.

Yes, also include 16340, the rechargeable battery
This one seems awesome

Agreed. Wish they put in an XP-L HI though. Are specs available for primary AA and primary CR123A?

I was going to suggest the Nitecore EC11, but I checked the specs, and it is rated at only 430 lumens with a CR123A, but 800 with an IMR Li-Ion. I don't really understand the difference, since I can't believe one volt or less would make that much difference. It must be that the IMR cell doesn't sag its voltage as much under load, but still. Anyone out there that understands drivers better than I do and maybe have an explanation?

Sure a factor will be the cr123a struggles over 1.5a as well.
You will see this output with the first gen XM-L U2. Eagletac D25C 770 lumens.

These lights use 18350 Li-ion, not 16340. I run mine on Keeppower IMR 18350, and its output is pretty good. Although I am not able to measure lumens myself, I have read reports from others who measure over 900 lumens. DBCust got 986 lumens on Efest purple 18350.
That's what I have read, too. CR123A is rated by most battery manufacturers for a maximum continuous discharge of 1.5 amps. Voltage sags badly above that.
CR123A were great for the incandescent flashlights SureFire was building twenty-five years ago. Frankly, however, they cannot supply enough current for modern, high-power flashlights. They have a place in the flashlight world, but not in applications where you are pulling 3 amps to generate 1000 lumens.
Their small size, long storage life, and good performance at both low and high temperatures mean that CR123A batteries will be around for a long time. Just don't expect high output.
The Olight S1 is a good example. In Turbo mode, it pulls over 2 amps from a CR123A battery in order to produce a nominal 500 lumens. But that doesn't last. The S1 has a timed step-down at 90 seconds that reduces output to 50%.
Notice I said, "nominal." If lumens, battery voltage, and battery amperage were measured during this 90-second run, I suspect that they would reveal a battery that was struggling to keep up. I believe the S1 uses a boost driver. If true, then it would demand increasing current as the voltage sagged. That's going to be nearly impossible for CR123A.
