None have mentioned the Nitecore Infilux with the XP-G R5...and it's still available on sale at a few places, (also avail with XM-L) and meet all your criteria. Probably the closest match to the OP's original request, and a very nicely constructed light w/McGizmo style clip.
I don't know your reason for needing/wanting a clicky and a Mag ring, but I have the V11R, Jetbeam RRT-01, and Niteye EYE 10, and much prefer the RRT-01 and EYE 10 with the only control being the ring (and I thought I wanted a clicky too)...parasitic drain is no worse than with a clicky (V11R), and a mag ring (only) gives you instant control over any level you want with no changing of handholds...no inadvertent full blast turbo, when you wanted moonlight...and no clicky to fail.
The only thing the clicky really buys you in this format is a tactical overhand grip, and if that's the case there are better choices for that application.
After approx a year of carry with the EYE 10 and RRT-01 these are by far still my favorite small EDC light UIs, and have been utterly reliable in hard use.
EDIT: The V11R is a nice light when new but I've had several of these Sunwayman V-series lights (V11R, V10R, and V10 Ti+) and can attest that after dropping them on hard surfaces a few times they all developed rattles at the reflector and switch and the anno was chipped badly (v11R/ no SS bezel)...the EYE-10 and RRT-01 still look and function as new.
