Some of my most frustrating times hunting were with the old mini mags. They would die after 1.5 hrs and leave you in the dark in a wilderness trying to change the batteries.
I don't think a g can beat those 120 lumen Ray O Vac mini flashlights at HD for $20.
I like the light headlamps without that big battery pack on the bk of your head- not needed with today's tech. I like the Princeton Tech or similar models with the small wide angle LEDs and also one high output spot for about $35. The single spot LED headlamps make me a bit woosy for some reason during a long hike in or out in the dark- the wide angle lights don't.
The small and light headlamps with 3 AAA batteries are so light you hardly know you have them on, you can carry a backup even on a UL backpack trip, and they will last for a 10 day trip with 2 hour hike in and outs in the dark no problem, probably more but I usually change the batteries every trip.
