Unsure? I'm friggin sure it is, utter bullsh1t.
For a walk about light imo the 240 blitz is too big. Go the 170 striker or even the 140 thingo..... Light force are light weight too, another bonus for a walk about rig...
I have both the 240 & 170, and the 170 really doesn't give that much away to the 240 in terms of a bright deep pencil beam...
Light Force do not exaggerate on their candle power output either.
