I looked a while back for a water-proof (or resistant) headlamp and
there were only two: one resistant to about three feet for ~10 minutes,
and another resistant to ten feet for ~30 minutes. Both of these were
pretty expensive, $50-$75 IIRC. Mountaineering-equipment retailers will
have them.

Well, you'd have to provide the strap, since this is designed for "real"
waterproof applications where you will have a mask strap handy, but it
is "really" waterproof (500 ft rated, I'll stick to 130 myself)

However it's 4 cells, so not what the OP is looking for.
