I just pre-ordered one of the new Quark Atoms in 123.
Tiny, tiny stainless steel shell; wide 120 degree pure flood. Is it the smallest 123 light out there? Must be close.
I have it's AAA cousin, the Preon 0, and love the quality of light that it puts out--the purest, even-est flood I have seen.
It's not going to be perfection--the tint will be too cool, and it has no sublumen setting, which is a shame. Also, it was a mistake to go with an XPG instead of an XML--when you want pure flood, there is no reason to go for the tighter emitter, and and XML would have given better run-times.
So it won't be perfection, but I think it will be pretty sweet!
And I ordered the headlamp that comes with it. A ball joint, basically.
