nice to be able to see the path ahead a bit.

For many years I've used a carbide lamp with a somewhat oversized
reflector. 4 hours operation on a film can of carbide. Good flood at
your feet with a real reach to the spot. I've been experimenting for
years with everything from candle lanterns to an inverter operated
flourescent I built in 1960. Until the LED lights came along there just
wasn't any serious competition to the carbide lamp.

I was recently given a gift of a Princeton Tech Attitude light
http://www.princetontec.com/
Three LEDs, 4 AAA cells, very convenient shape/size, o-ring seal, good
output for walking around. Manufacturer claims "up to 150 hours". MEC
(a Canadian outdoor retailer) claims "more than 50 hours" which I expect
is more realistic. When I run down the alkalines that I have in it, I
may put in Lithiums if they are available in AAA.
