i run 100% in the dark - 4:15am each morning - my longer runs finish isn the light but obviously - you need to see in the dark - btw - LOVE running in the dark - street to yourself, quiet etc - anyway

1. never used a flashlight - but the headlamp should go on your head and believe me - after awhile you wont even realize its on your head - i have a princeton tec - it cost about fifty bucks but the light angle is adjustable

2. i forget how many lumens (i got the one for 50 at dicks - i just checked the lamp and it doesnt say - it was the brightest they had) and def bright enough - goes thru batts quick so i click it off (easy enough) when in sections lit by streetlights

3. yes - put it on your head

enjoy

edit: i also wear a reflector vest and led blinker - more important than seeing where u are going is other people being able to see where u are going

and dont worry about looking funny with a headlamp on - its early (or late) and no one really cares - btw - try throwing on some camo vibrams and then you'll feel funny:)

I've never used a flashlight to run.  Always a headlamp.  They are great.

I use MicroLites.  Very small.  Very powerful LEDs.  Cost only $8 at Outdoor World.  They weigh only an once or two.  I put two on the front of the bill of my cap.  I can see the road/path in front of me  ...  and better yet the bikes can see me.  I put a red one on the back of my cap so riders can see me as they approach from that direction.

I am astounded at how many runners and bikers are on the paths in the dark.  Seems like a disasterous formula to me.

I haven't totally figured this out either... today, I had my best run ever! When I got home from work I just knew I should go out and run. Problem - it's dark and not even 6pm! So for today's run my answer was to wear a white shirt and run in front of dh on his bicycle which has a headlamp. I think the headlamp on your hand would be a solution that I could use too... you can move it around where needed instead of just having it on your head. My grandson asked me to buy him some reflective tape, and I am going to make some sort of bracelet / anklelet things with it for running in the dark.

Headlamp on head seems to work best.  On your head the light is always pointing where you are looking.  It is a little strange, bouncing on the forehead but you get used to it.  I have one of the $20 pretzel lamps with 2 LEDs, 2 intensity settings and it needs 2 or 3 AAA batteries, .   It really freaks out drivers sometimes.
