And here are a couple shots of my own.
Q-III on a fresh Surefire 123 on the left. I believe the emitter is SYOK.
Fenix L1P v2.5 on the right, with a fresh Energizer 2500mAH NiMH.
The beamshots on top were taken with the lights about 3 feet away from the wall.
The images of my garage were taken from about 10 feet away, with an attempt to center the hotspot on the doorknob.
