I've had good luck with this LED headlamp (the lime-green HD Plus model). I like its one-touch-off feature but it takes a bit of mental adjustment.
The headlamp has four light modes, including red. The trick you have to learn is to decide what mode you want before turning it on. If you click once, you get red. If you just leave it alone for two seconds at that point, your next click will turn it off (not advance to the next mode). That's very handy for preserving your night vision.
For the other modes, you click the number of times necessary to get to the mode you want (from OFF). For reading, I know I click four times for flood-only, then hold down for dimming. After I'm done reading, one click turns it off.
The spotlight is 200 lumens and supposedly good for 70 meters. I tend to use flood mode most of the time I'm out at night but will click on Spot if I want to look for those spooky red eye reflections out there in the scary woods.
The headband is comfortable and I like how far the light tilts out from the battery-pack to adjust the light-angle down in front of you. Battery changes are easy.
I believe I bought mine at Lowe's or Home Depot. About $20.
