Mark,
My absolute favorite light - of any kind - is the Princeton Tec EOS headlamp with the rebel LED. It takes 3 AAA batteries.
I'd call it a floody spotlight.
The highest level will light up camp. The mid-level is great for most uses. The lowest level is just enough for inside a tent.
I have two in my drawer next to me, one in my travel bag, and another next to my bed upstairs.
I was a Scout leader since my son jointed at age 6 through his 17th birthday, and found that the EOS headlight was all I really needed. Compact enough to slide in a pocket on the way to camp (driving), super bright at high to see what's on the other side of camp at night, dim enough at low, lasts a good long time on medium, and waterproof.
Some Scoutmasters are really into using gas lanterns and like to leave them on all night - turning night into day, but personally I think boys should learn to live and enjoy the dark, and when things get too dark to work then learn to use headlamps at low settings.
