I just got an Outad headlamp (Amazon) that I'm happy with so far. The price is right and it does many things well. High light that is really bright, low light that is enough in most situations, very low white or red light for walking into your high seat or blind, a USB charger and it is waterproof, I hope it lasts, time will tell. My old headlamp from Cree is still going strong after more than a decade, used often six times a week. I have a Browning clip onto hat brim low light lamp, not much more light than a candle. I got it as a giveaway at a firearms exposition.
I also have a hand held pistol grip type spotlight, Dewalt, that uses the same 18-volt battery as my drill and charger. Pretty much the Cats ass if you have to track at night. It throws a nice beam out to around a quarter of a mile.
Something to think about is reflected moonlight with the light off. I once watched a buddy blink his way through the fields with his light off, I pay attention now. I don't know about your Hogs, ours will spook at any light, even a car at half a mile or so. I've spooked them with the low battery light on my thermal scope. Anybody who says a Hog can't see a red LED is likely mistaken.
