Fantastic concept and execution.
Kudos.
I was running a short time (30min) in the woods last Saturday.
Most of the time I used flood only with around 100mA driven through the MC-E.
When adjusting the three LED group's current I have implemented 13 levels with an relationship of 1,41 between the next higher/lower level (logarithmic).
100mA results in around 1,3W per MC-E and with the 12 flood MC-E and an efficiency of 100 lumen/W at these low drive levels I run with ~1500 lumen through the woods.
This level would last for 70Wh / 15W -> at least 4 hours.
From time to time I used the "Far-Sight" pushbutton that switches of flood and turns on spot and mid to max power. When releasing it restores the old values. This is useful to get an overview over the whloe trail in front of you.
And as it was my first run with the new light I certainly stopped several time to point around with the 110mm aspheric beam or to light up a whole clearing with the "Full-All" button.
I also tried the "Strobe" button for some seconds, and it's really hard to keep running with the strobe light....
To summarize I can say I adopted the control interface to my needs and am nearly satisfied with it. It's useful and fun at the same time.
Considering the lamp's weight I can say: It is worth being carried for the fun it grants....
