Yeah, I wasn't trying to 'compare' and HDS to a Hotwire Mag mod, I just meant that with basically zero ambient light, an ~80 Lumen single LED light in a small reflector can easily get past 100 yards while while your MUCH brighter light is having trouble going 25% of that distance.
I did a couple brighter hotwires, but right now the brightest incand lights I have are a Streamlight TL-3 and a ROP Low and in those low ambient light conditions, they can both EASILY throw WAY past 100 yards.
For the most part, almost any hotwire over 200 lumens in a smooth or LOP reflector should be able to effortlessly illuminate well beyond 100 yards.
