My first post after lurking a long time. Thanks for the great forum, and esp. to selfbuilt for the incredibly detailed and photographed reviews!
I'm puzzled by the different run-times at 120 lumens claimed in the product specs of the JetBeam BC-40 (2x19670) vs. a Balder BD-2 (1x19670):
BC-40: 11 hrs @ 130 lumens (low setting)
BD-2: 10 hrs @ 120 lumens (medium setting)
Given that the BC-40 has twice the mAh, I would expect about twice the run time, discounted by ~8% for the 10 additional lumens. What gives?
Also, the color temperature of my BD-2, Fenix TK-35, and Nitecore TM-11 are a nice neutral white, but the BC-40 is much warmer.

Could the BC-40 be an "XL-M Warm"?
Do any manufacturers disclose which of the three color temps are used?
Does Cree offer the three color temps in all Group Codes?
