i have a western rivers "the knight"
its 21 volt with a rheostat,hi/lo setting and the handheld light is pretty bright,i have seen eyes past 200 yards but i can't really tell what the eyes are on.i have taken the headlamp and made a holder from a old bi-pod that now mounts onto the sling screw.it is very capable of eyes to about 125 yards.the hand held doesnt eat the 1.3lb battery up uuntil about 3 hours of pretty much steady on use.i think i paid around 300,and i dont think for myself i will ever purchase another light.the bulbs (the good ones)are a 35watt 12 volt and are about 5.50 each,it also has a slow-burn fuse to protect the bulb.it also has a small blue walking light that can stay on for weeks it seems
