I have been using headlamps since before you could get an LED version,(that was anywhere near bright, and actually white) mostly for frog gigging. A red lens is a real help with that. most of the lamps I have are Petzals, they make a dam fine light.
the headlamp I use the most, when not hunting, is a simple $14.00 energizer LED, with 2 white and one red LED. You can get them at Target, walmart, or just about any auto parts store. I have one thats atleast 10 years old and it still works fine. the run time is 65 hours so it will get you through the night pretty easy. the down side is it uses 3 AAA batteries. the Petzal Tikkas are nice but a little more money.
energizer does make one now that uses a single AA battery, and has an adjustable white spot light, it goes from 65 lumen down to 12 lumen, and one red LED. The one major problem i see with the high intensity headlamps(over 80 lumen) is when you are using one(a headlamp) when you talk to people you have a tendency to look them in the eyes, with a 80 or more lumen light that actually hurts. hell with 200 lumen you can cause some damage.
my advice would be keep it simple, but definitely get a headlamp, it will change the way you do things at night.(you do it with both hands and without a flashlight in your mouth, that means no chipped teeth)
good luck
