Single-cell 123 Cree lights: runtimes

[Fallingwater]

I'd like to have some runtime figures for Cree pocket lights using just one cell.

Could you please post your flashlight type and brand, battery data (brand, primary or RCR, capacity and voltage for rechargeables) and the run times you've seen with the batteries you've used?

Thanks

I posted runtime info for McGizmo's Ti-XR19-C in the first post of this thread. With a fresh Surefire CR123A, it ran for 65-70 minutes on high in regulation, then ran another 20-25 minutes with diminishing output.
