Hi Dave, yeah foxes were shot over a couple of nights. The ones lit up red at the start, were shot on a night where two of us called and shot 19 foxes on foot using LED torches. Whistle was a shotgun shell brass job.
Burkey, the camera is an ATN Shot Trak, can be had off eBay for $240.
Yeah you'll get that halo with any reflector torch, even the long range Olight Javelot has that.
M9 should be good for knocking foxes to about 200m though, which is a long shot at night.
You want the 4.2V setting mate. 18650's are a nominal 3.7V but will hit 4.2V fully charged. The 3V setting is for RCR123 batteries. 18650's can take a long time to charge if they are below 3V, can take several hours.
I use a similar light for spotting eyeshine in my hand. These lights use the common P60 dropin so you can switch to different or upgraded dropins including red, green, etc.
I would suspect that the Solar force M3 head would screw onto it.
The Zeus will work fine on a .22 etc out to about 100m.
If you want a budget long thrower, as my friend above said, get this:

You'll need to get some spare batteries, like these:
17670 is same size as two cr123.

But only 3.7v and 1400 capacity so worse than two cr123 in capacity.
Turf the old bulb and run this:

Got me buggered. CR123 / 16340 and 18350's in pairs should run it. Something going on in the driver I reckon. My new K3 (MT-G2 @1500 lumens), Pro-1 and M3 will all run on a pair of RCR123's.
I have found this to be a good solution, if a high powered head torch is required. I use one for night time shotgunning with a lightweight Solarforce P1 polymer
torch.

Any small and light torch will work, something like this for example.
