I have had the best luck with a bow mounted light. Headlamps are tough to manage as far as where the beam is hitting while the hogs are on the bait. As stated, start with the light above the hog and drop it down on them. I have had the best luck with a red light, the green, not so much. For what its worth, I am a fan of Sniper Hog Lights, great people to do business with and a well built product. I use $10.00 solar lights from Wally World to keep a constant light source on the bait, and I keep the solar lights between the hogs and my stand. Good luck!
