I dont need a pure thrower. I work on the railroad and I want an effective range of 1-200 yards.
Forget the SC600 then, 200 yards is way out of its useful range....50-60 yards, borderline, more than that, its too dark past the flood.
The Klarus XT11 is pretty effective just shy of that range...on an 18650, but would work on two RCR123's...but the run time would be shorter...so, if 200 yards is a distance you need to light up, you do need a throw capable light.
If looking for people hiding, etc, or vandalism, damaged missing cargo/equipment, etc..the ANSI 0.25 lumen range will be woefully inadequate...you'll need a lot more lux on target to resolve the details you are probably looking for.
For less $ than the SC600, you could get a Crelant 7G5 V2 that would light up that range very well, a little higher lumen output than the SC600 on turbo, but, a less floody beam. The beam is still large enough to see context, etc.
The Klarus XT20 would be more $ than the SC600, but would have roughly double the lumen output, and a floody beam with the throw you need.
The key issues with lights for patrolling involve the fact that a floody beam is so much more useful most of the time...but, to make a flood light throw, it requires an ENORMOUS amount of lumens...as the lumens have to light up a very large area.
So you either carry a smaller floody light, with a larger more powerful light on your duty belt, etc, so you use the floody light for most of your walking around, and whip out the big bad boy to check out the next yard over, etc....
or, suck it up and just buy a large powerful light that has low modes and a floody beam, so it can cover the walking around and reading maps/meters...and ramp up to spot a perp 200 yards away hiding in the weeds.

An Xtar S1 for example, etc.
