I have a HA McKinley Hi-power in regular white. My beam is a little blue, but very smooth due to multiple leds. Fit and finish are excellent. The beam reads a little over 100 cd at the center. Haven't run it long enough to determine run time.
It's a nice light but has a relatively narrow beam due to recessed leds, much like the beam of a Dorcy 1xAA but brighter in the center (it measures about 4x brighter, looks about 2x or 3x brighter, due to how the eye sees things).
I would have preferred something with more sidespill, but it's an elegant looking light about as small as you can get a 123A light.
If I had the choice of what to buy now, I might go for a Nuwai QIII instead.
